You can change the "fundamental" pitch of the instrument, and shift all the pitches to a different key. The range of this shift is extensive, so you can get pretty much any range you wish.

I believe that the "fundamental" depends on what fingering pattern you have seleccted ... not sure about that, and my Sylphyo is (uncharacteristically) not handy at the moment.

What you can't do from the Sylphyo is bias in microtones (less than a semitone). The Sylphyo is sending MIDI notes, and it would be too much to ask to send accompanying pitch bend commands to accommodate microtuning. This is usually handled by whatever software (or hardware) is rendering your MIDI stream.

I hope this helps!

@ark I might look at some of the hardware filters such as Midi Solutions Event Processor (or Event Processor Plus). Short of sending all MIDI through a Computer/DAW setup, where you would have extensive MIDI manipulation capabilities, these hardware boxes can work well and with very low latency ...

I have been doing some testing today with the tubular version of the hydrophilic plastic that is shown in the video ... and it does not seem to absorb as much as the simple flat piece of the same material.

I think there is less surface area on the inside of the tube than the two-sided flat surfaces of the rectangular version.

Just posted a video on hydrophilic inserts for the Sylphyo.

@Peter-Ostry Good question!

I was thinking it was not an issue since the Line outs are unbalanced ... but the 48v circuit is established between XLR pins 1 (which maps to the sleeve) and both pins 2 and 3 (tip and ring) ... so if you go to unbalanced (and drop the ring / pin 3) there will still be a voltage drop across the Tip and Sleeve ...

@ark Welcome to the Club!

@ark said in Why can’t Note-off Delay be Zero?:

should be treated as a bug

Thanks @ark! I know understand the legato protocol better ... but I'd really hate to add a physical box to my rig and introduce latency just for this bug ...

Not sure if a bug fix at that low level is a possibility these day ... been quite a while since the last official firmware update ...

@Sylphoboe ... "enriching the original sound bank" (that's what Google Translate produced) would require a firmware update to the Sylphyo. The Sylphyo firmware has been stable for almost two years - no official updates - although there may be Beta versions (issued somewhat privately) for testing new features.

The most recent official firmware release - v1.4.8 - was dated 30Mar2021.

I have been working for several weeks now with some samples of a porous, hydrophilic material sent to me by flutemaker Edward Kort. They are custom cut from a 1/4" thick sheet with 10 micron pores supplied by Scientific Commodities (Cat #BB2062-10BL) that can be found on this page: https://scicominc.com/porous-plastics/porous-sheets/. Photos are shown in the earlier message in this thread.

My experience so far has be very positive. The material is easy to insert and remove from the standard Sylphyo mouthpiece. It does not cause a noticeable change in playing characteristics. The insert absorbs a substantial amount of moisture holds it, and dries out when removed (I typically dry it overnight).

The inside of my Sylphyo has gone from “large moisture droplets on the inside walls of the Sylphyo which coalesce and drip out the bottom” without the hydrophilic inserts to “light dew / haze on the inside walls” with the insert.

I am still on the road so can’t do a more detailed study (like weighing the insert before-and-after to determine the amount of moisture absorbed).

One concern is how oil (e.g. from handling the insert with fingers) might affect the long-term performance of the insert. There is apparently no remedy for hydrophilic material that gets clogged with oil. I am hoping that with reasonably careful handling (by the edges and just the area at the distal end of the insert), an insert might last a year or more. Edward Kort’s philosophy is (personal email) “make a pile and replace as necessary. It’s easy to check the condition of an insert: hold it to your lips and blow. If you can’t move any air, trash the insert.”

I was also concerned about possible shedding of fibers. Edward Kort’s feeling is that “I’ve never seen any fiber shedding; this would be a very bad characteristic in an industrial filter material. That said, the cut edges are feathery – probably due to the nature of the pore structure. With my NAF application (with the insert in the bird), I want the flue-exit end to be very smooth. I accomplish this by masking the surface of the plastic and apply CA glue just to the end. This end can then be smoothed and shaped. Works great, but it is an effort to implement. For the Sylphyo application, I don’t see any reason to seal the ends.”

He has also tried several variations:

I use two formulations of the plastic: the 10-micron pore style that I sent you, and a 30 micron pore size. The 30-micron product is much harder than the 10. It is not spongy at all and seems a bit more durable. However, it must be sawed rather than cut, and it contracts a bit when wet. This requires me to glue the insert into the bird channel, whereas the 10-micron product can just be press fit.

When I get back home (4 months on the road so far – great experience and somewhat exhausting. Just did a concert last night …) I hope to delve more into these inserts …

@mathiross It would be great to get a few photos of your setup ...

The lowest setting for [MIDI Mapping] => [Note-off delay] is 1ms. Wondering if there is a reason why it can’t be zero.

I'm running into an issue in legato situations where I change fingerings on the Sylphyo, but the "from" note and the "to" note are the same. This happens for me in situations where I am doing note translation – as for my harmonizer. The MIDI looks like this:

… with the [Note Off] occurring after the [Note On]. This causes many of my virtual instruments – the Turbo VL70, SWAM engines, etc. – to go silent indefinitely (i.e. until I change to another note that is not G4).

If [Note-off delay] could be 0ms, then the [Note Off] might occur before the [Note On]. Maybe?

I see no way to fix it at my end, other than a ReaJS script or some other gnarly solution that would probably introduce latency.

Any thoughts welcome!

@Peter-Ostry Sound great!

See This Post for a case that I use on the road.

It has performed well!

I have been contacted by a very experienced flute maker and Sylphyo owner - Edward Kort - who has been following this discussion (but cannot respond here because he has yet to be able to get his forum membership approved).

He has successfully experimented with using a porous, hydrophilic (water-loving) insert into the standard Sylphyo mouthpiece. The material is a specialized polyethylene, treated with a surfactant to absorb moisture up to about 40% of its volume.

He reports good results - reducing his usual time-to-first-drip out of the bottom of the Sylphyo from "a few minutes" to "nary a drop after 30 minutes".

He is sending me a sample (arriving in a week) for testing.

Here are some images he sent me:

He sourced the material from Scientific Commodities. The particular material he is sending me is from a 10 micron, 1/4" thick sheet (Cat #BB2062-10BL) that can be found on this page:

https://scicominc.com/porous-plastics/porous-sheets/

... however, for our purposes, I am looking at the possibility of using their porous tubes ... something like Cat #BB2062-5075A1L from this page:

https://scicominc.com/porous-plastics/porous-rods-tubes/

Just some rather substantial confusion with my rig setup (Sylphyo wind controller and SWAM flutes under Cantabile on a PC). Hoping this might shortcut the same issues for others ...

The symptom was that Main Volume in the SWAM instruments appeared to be corrupted, getting snapped down to -26.2 dB. This really messed up the balance in my set list from one instrument to another.

With assistance from Emanuele Parravicini at Audio Modeling, I was able to diagnose the cause:

The Sylphyo has a "Quick Set" for volume that I was not aware of (even after 2 years of playing it as my primary instrument). There is a little-known combination of keys (hold the Aodyo key and tap the pitch-bend slider) and you can adjust the internal volume of the instrument. This was not important to me, since I only use the internal sounds (and volume) of the Sylphyo as a disaster-fallback.

It is quite easy to accidentally hit this Quick Set combination when setting other things such as the Base Key or the MIDI channel.

Changing the Volume on the Sylphyo sends CC07, and the SWAM VSTs respond to that, setting Main Volume.

An accidental setting of 40% volume on the Sylphyo corresponds to a Master Volume of exactly -26.2 dB on the SWAM plugins.

Hope this helps!

@Peter-Ostry Great springboard ideas!

Some Native American flutes have such contrivances.

Basically I'm thinking of making a pocket / reservoir inside the mouthpiece at the gravitational bottom of the mouthpiece (in normal playing position) to catch condensate for later occasional clearing by removing the mouthpiece (every 30 minutes?)

Playing a lot these days (and nights) and want to avoid moisture issues ... with a Blues band the other night ...

Wondering if anyone has experimented with or thought about a modification to the Sylphyo Mouthpiece to reduce moisture into the instrument.

I'm thinking of maybe an inserted component into the South end of the current mouthpiece (the large opening) that would catch and store condensation until it can be cleared.

I'm handy with a 3D printer, but most 3D filament material is not suitable for mouth contact (the microscopic pits in the surface make for bacteria condominiums).

@Peter-Ostry Yes, Linseed takes a looooong time to dry.

Perfect! Found the bit in the garage of the place we are renting ... 1/2 a turn did the trick ...

Thanks so much!!

The casing on the bottom half of my Sylphyo "A" is a bit loose. It creaks a bit when I squeeze it.

You can see it in this short video I took:

https://www.dropbox.com/s/mogb12p9zhakjzg/P1230429.MP4?dl=0

Can I stop this by tightening the bolt on the underside of the Sylphyo near the bell? This one ...

https://www.dropbox.com/s/80lo6eg2h8gokur/P1230430.JPG?dl=0

If so ... what kind of a bolt is it? And can I buy it??

@Peter-Ostry Sweet! Looking forward to feedback on how this pans out ...

Love to hear input from @Laurent_AODYO or other Aodyo folks on this low-moisture direction ...

I've been playing out a lot lately and really pushing a lot of moisture through the instrument. I probably swab out 5 times a day. My Sylphyo "A" is still holding up with no ill effects. Sylphyo "B" still does not pair with the Link and may need to be looked at ...

Simple solution: filter out CC#2 = 0.

Bingo!

I do it in Cantabile (excellent live performance DAW) with a filter that only passes CC#2 if >=1 on the route to the Duduk VST. I'm guessing most DAWs should be able to filter MIDI in this way.

Using Super Duduk for our walk-on opening to the next concert ... (with piano and percussion) ... really needed to solve this because I would articulate notes and nothing would happen ...

Gino (of Suonopuro) has suggested changing "by dyn. c." to "by keys" on the interface of the Duduk VST. However, this did not help ... since the problem is with the note's attack (not legato).

What does help is changing the Sylphyo "Note Off Delay" to 10ms rather than 1ms. I'm not sure if that means there is an additional 10ms latency on everything I play (yikes!)
Unfortunately, I cannot send Sysex to the Sylphyo to change configuration (i.e. between songs) - it has to be done by hand on the back panel, so this is a hassle during a performance.

Does anyone know the overall effect of "Note Off Delay" ... does it introduce latency across the board??

I have encountered an issue playing the Suonopuro Duduk (Gino Chimenti) with the Sylphyo. The symptom is that soft attacks on notes produced no sound, regardless of how much breath pressure I supplied after the soft attack.

Here is the MIDI from a normal attack:

… which produces sound as expected from the Suonopuro Duduk VST. However, the following MIDI generated from a soft attack produces no sound:

The issue appears to be the 0 value for CC#2 after the Note On message.

I tracked the problem down to a setting on the Sylphyo: [MIDI Mapping] => [Note-off delay].

My initial testing (which cause the problem) was with [Note-off delay] set to 10ms. Changing that value to 1 ms dramatically changes the MIDI stream on soft attacks:

Here is background information on the [Note-off delay setting], from the Owner’s Manual, 10Jan2022:

“Set the time before a note-off MIDI message is sent. Increasing the delay will help the Sylphyo send no more MIDI note messages than is necessary, but might prevent the MIDI flow from accurately describing dead notes and flutter-tongues. Decreasing the delay will help polyphonic synthesizers better understand the MIDI flow from the Sylphyo.”

… and from the release notes for firmware v1.4.0 (6Mar2019):

“Improved the handling of MIDI note-on and note-off messages. You can now control the delay before a note-off message occurs using the Note-off delay setting in the MIDI Mappings section of the settings menu.”

I am wondering if other folks have encountered issues such as this with other soft synths ... or if there are any thoughts on the Note-of delay setting ...

@wwoodard8 I believe it is the Photon mouthpiece. A good overview is in a forum post Here.

I have heard that the project has been delayed by lack of chip availability ...

@Peter-Ostry I have seen Shakuhachi players keep their instruments in a Lexan box with an open glass of water inside that keeps that humidity at around 50% (I was told), which apparently good for that bamboo-based instrument. Maybe something like that?

Success!

I used This Kit, practiced a bit, and (I believe) successfully closed the hole. I did this repair after leaving this Sylphyo (my Sylphyo "B") open with the blue ring off for two days to let any moisture dry out before I sealed the hole.

I wanted to avoid dripping hot glue down into the hole, so I positioned the Sylphyo horizontally with the open port on the bottom, hanging off the edge of a table. I did not remove the old glue, as it was already closing a good portion of the hole. The newly applied glue melted the older glue and they seem to form a tight seal.

Here's a pic of my repaired Sylphyo "B":

... and here is my Sylphyo "A", which appears to have a well-sealed active mouthpiece port:

THANKS to @Laurent_AODYO and @Peter-Ostry and @Fanch35 who provided info and support on this issue!!

I print headjoints for my Breath Flute project in different colors and materials (PLA vs TPC/Copolyester), so I need to store them for a long time.

I keep each roll of filament in a separate, re-sealable (Zip-lock) poly bag with it's own renewable dehumidifier and a small individual hygrometer. These bagged filament rolls are grouped into clear 44-quart storage boxes.

More info on the individual components:

• Poly Bags: I generally use 4 mil "poly" bags from Plymor or Uline. They are made of LPDE and Polyethylene, respectively. The 4 mil thickness feel reassuringly solid. The Plymor bags are on their store on Amazon: https://www.amazon.com/stores/page/12B315CE-97CA-472B-9026-DB8732D7F438 . Uline bags can be found at: https://www.uline.com/BL_211/Uline-4-Mil-Reclosable-Bags

• Dehumidifier: I use Eva-Dry E-333 dehumidifiers. They convenient, have an indicator as to remaining capacity, and can be renewed by plugging them in for 18 hours (no more than that!). They bring the relative humidity down to 10-15%. The manufacturer's page is at https://www.eva-dry.com/product/e-333-renewable-dehumidifier/. They are available on Amazon at a discount.

• Hygrometer: I use inexpensive EEEKit 56 mini hygrometers. They are no longer available, but an Amazon search for "EEEKit 56" produces lots of similar units.

• Storage box: IRIS USA WSB-SD Ziploc WeatherShield 44 Quart Storage Box, Clear. https://www.amazon.com/gp/product/B07C882DVV/

So, possibly a similar setup using poly bags, or maybe a clear Lexan box of some sort ...

I do use a dedicated filament storage box / dispenser for filament that is being fed live into the printer. That specific box is by Polymaker and is here: https://www.amazon.com/Polymaker-PolyBox-Filament-Filaments-Printing/dp/B075DBPY6F. However, for other ideas, search on Amazon for "3D Printer Filament Storage Box".

I am wondering if it is a good idea to store my Sylphyo in a low-humidity environment.

I keep my 3D print filament in airtight bags with desiccant units that keep the humidity at around 10%. Easy and works great.

Given the array of issues I (and others) have had that seem to be correlated with moisture, might a 10% environment reduce these issues?

If this is a good idea, I can provide the specifics of the products I use for moisture control with my 3D print filament.

@Peter-Ostry Thank you so much for all the info!!!

Hot Glue gun is on it's way ... I'll keep y'all posted ...

@Fanch35 Thanks for the suggestion. Unclear whether Flex Tape bonds to ABS plastic, but I suspect not. (for the material used in the body of the Sylphyo, see https://community.aodyo.com/topic/687/what-type-of-plastic-is-sylphyo-made-of). Flex products in general are heavily promoted to consumers, but don't seem to get high marks for their ability to seal larger than pinhole sized openings.

Searching for the right tape is challenging. Tapes that seem to fit the criteria appear to be difficult to obtain in small quantities (e.g. Bron BT-246). Many consumer tapes are fuzzy on what they will bond to, how removable they are, their water-resistant properties, how stretchy they are, how thick they are, and other important characteristics.

Wondering if @Laurent_AODYO other other knowledgeable folks in this area could make a recommendation for an obtainable (like on Amazon) tape that might work well ...

It appears that these issues I am having are related to moisture infiltrating the electronics portion of the instrument. These are (I believe) due to several issues:

• I have been storing the Sylphyo horizontally overnight. Not good. I am on the road and horizontal is easier for me, but I think bad for the Sylphyo. There is a recommendation by Aodyo for vertical storage (not in the general documentation, but mention by Maxence here: https://community.aodyo.com/topic/663/a-gentle-breeze/6)

• There may be a moisture path because the active mouthpiece port on my Sylphyo is not completely sealed. See https://community.aodyo.com/topic/2158/under-the-blue-ring

I have fixed the first problem and the behavior is improving.

@Peter-Ostry How interesting. Thank you both the the info and the insight.

I am on the road now, so all modifications (like obtaining Hot Glue, which I have never used) are more difficult.

I believe that the O-Ring on my black mounthpiece does not make a perfect seal, since there is a very slight wobble in my mouthpiece when it is fully seated. Not a problem playing, but maybe there is a slight moist air leak back up underneath the blue ring.

I am not sure what the air-path is that you are describing here:

the inner gap between the housing and the blue ring.

... maybe it is outside air? Or is it some breath moisture air?

with your fan without a mouthpiece,

I am not currently using a fan while on the road.

At home, I store my Sylphyo vertically in a 3-D printed stand (https://community.aodyo.com/topic/606/floor-stand/7). I do use a fan to pull air down the Sylphyo. This seems to work well ....

On the road, I am using a cradle (https://community.aodyo.com/topic/606/floor-stand/5) that stores the Sylphyo horizontally, and I am not using a fan. I think this is not a good idea. I have been having more and more issues, which I suspect are related to moisture. Failing to send MIDI when paired with the Link, Unable to initiate a pairing from the Sylphyo, and even failing to send send MIDI over the USB connection.

I am still laying it down horizontally while at gigs, but overnight I am now standing my Sylphyo up on end and leaving it open to dry (and removing the blue ring). This is a bit risky (it is just standing on its bell end) but the behavior of the Sylphyo is improving.

Since I have no experience with Hot Glue, I have many concerns with attempting to seal the active mouthpiece port.

• Will I melt the plastic of the body of the Sylphyo?
• Will I drip glue into the active mouthpiece port and into the Zone of Electronics?
• Will some undreamt-of calamity befall my Syphyo in my fledgling attempts at Hot Glue Art and I'll be left playing a kazoo at gigs.

Maybe there is a tape of some sort that would stick, provide a seal, and be safe?

Pulled my Sylphyo out of its case last night just before a gig and grabbed it by the blue ring. Pulled it straight off (yikes!). Put it back on, no problem, but then I took a look at what was underneath:

My concern is the area in the red circle. It appears to be some port or hole that is covered with a membrane or glue that ... maybe ... is sealing this port or hole? It is not completely sealing the port, and I'm wondering if this is allowing moisture into the electronics area of the Sylphyo.

Suggestions as to what I should do would be welcome ...

@Peter-Ostry Thanks Peter! I actually think I'm gonna sit on a stool and adopt a more "grounded" approach to these next 5 gigs.

Three folks on the Facebook Sylphyo Exchange have also reported this issue, so I think it's a real hack (and not just on my system).

I can no longer pair my Sylphyo. On this menu item:

https://www.dropbox.com/s/i6joj8iatn03c5u/Sylphyo_PairingGetsLost_MenuItem_800c10.jpg?dl=0

[Receiver devices ((?)) DISCONNECTED (CH9)]

... clicking 2nd octave button from the top (on the back of the Sylpho, the one that usually causes the action) causes nothing to happen. I have tried for the two hours. I've power-cycled the Sylphyo maybe 40 times. I've waited 20 minutes with the Sylphyo powered down. I have reverted the firmware on both the Sylphyo and the Link back to the last official firmware version 1.4.8.

I may be reduced to playing (performing?) wired ... not a great prospect, and problematic if I pull on the wire and damage one of the connectors ...

... and my other Sylphyo is still in France for repairs ...

It looks like the Aodyo.com web site has been hacked by some kind of DNS hijacking malware ... I get redirected to various alternate web sites when I go to web pages under Aodyo.com.

I have tried it from several computers and tablets.

I've experienced this for about 24 hours starting mid-day 12/24/2022I have run a check on our router, and that turned up clean, but it is still possible it is a problem with my system here ...

This does not seem to affect the https://community.aodyo.com/ message board ...

I have run a check on our router, and that turned up clean, but it is still possible it is a problem with my system here ...

At the advice of Matthias Couche (via email) I've reverted the firmware from v1.4.9b5 [3/15/2022] to v1.4.8 [3/30/2021] on both the Sylphyo and the Link. This did not solve the issue.

To review, the basic issues are:

• After the Sylphyo is powered down for "a while" (typically overnight, but as little as 4 minutes), it appears to pair with the Link (green light on the Link, Sylphyo configuration menu item shows connected), but no MIDI is sent.

• I have to try many times (2 to 10) to initiate a pairing from the Sylphyo. The menu item on the Sylphyo to initiate a pairing simply does not respond to selection.

@frank Thanks for the idea!!

(I was so busy trying to re-pair that I missed your message at first).

Thing is that this happens on lots of different channels. Every time is (eventually) get the Sylphyo to pair to the Link, it chooses some different channel.

Also ... aren't the radio frequencies used by the Link different from WiFi frequencies??

Could you suggest a particular WiFi app for an iPhone that I might try??

Here is a link to a photo of the Diagnostics screen when this happens (Sylphyo connected to the Link but sending no MIDI):

https://www.dropbox.com/s/kfwzuutqpoxfxd3/Sylphyo_PairingGetsLost_Diagnostic_1000c10.jpg?dl=0

More info:

The menu item that does not respond is the [Receiver device] item.

When the Sylphyo initially fails to send MIDI data, it is showing (below [Receiver device]) that it is "Connected: " and gives the channel number.

It is actually happening more frequently now ... with the Sylphyo being off for shorter periods.

I've had a syndrome for the last several weeks where the Sylphyo-Link pairing is forgotten by the Sylphyo. It occurs typically after the Sylphyo is off overnight (and typically recharging). It happens occasionally after it has been off for a short while.

• I turn on the Link.

• I turn on the Sylphyo and the light on the Link goes from red to green.

• I play notes on the Sylphyo and ... nothing. No transmitted MIDI and the light on the Link does not show the short blue pulse on each note.

The real problem is that, when I re-pair, it takes a long time and many re-tries to get it to successfully re-pair:

• I select re-pair on the Link (both upper and lower buttons simultaneously)

• I select the pairing menu item on the Sylphyo, and clicking the menu item does nothing.

• I turn off the Sylphyo, wait 10 seconds, turn it on, find the pairing menu item and click on it. Nothing happens. This typically happens 3 to 10 times. If this were to happen in a performance, I would run out of jokes to tell.

• After this extended period, it is finally successful. I cannot tell what makes it succeed (letting me select the menu item on the Sylphyo).

• When I am able to select the menu item, it does always succeed in pairing and all is normal after that.

I have done a full reset on the Sylphyo two times (and re-entered all my custom parameters ... by hand ... each time). The behavior has not changed.

I have power-cycled the Link numerous times, and nothing has changed.

I am not able to try my other Link unit, since I am on the road and have only this one Link unit.

I have never experienced this issue on the other Sylphyo unit (which is currently in France for repair).

Any help / suggestions appreciated ...

It is amazing how a thriving on-line community can self-support a user community and help a product to grow.

I am an active member of many communities using different discussion systems, and the difference between those that function smoothly and those that creak along is striking.

The best systems seem to be those that are based on trust levels (new users earn trust by posts that get positive response and get correspondingly more capabilities). They seem to create communities where the users (happily) support the product, essentially freeing the developers of most of the support work.

Not sure where NodeBB stands in capabilities, but it might not be up to the task. I have had very (very) good experience with Discourse (https://www.discourse.org/), which is used to run the Cantabile forum, an outstanding user community ...

@Friedus My personal belief is that "really good internal sound" needs a really good (i.e. reasonably current) CPU, fast memory, and all the things that support that (power, bus architecture, etc.) After being "pretty" happy with the results from the VL70-m for almost 2 years, I jumped into the Audio Modelling / SWAM sound engine a few months ago and left the VL70 gathering dust. That's for the real-world emulation camp.

For the virtual, more "out there" sounds, there's the Lyrihorn, Respiro, EVI-NER type plugins, which may require somewhat less "oomph", but still (I'm guessing) far more than the CPU power of the Sylphyo.

Cramming a SWAM engine inside the Sylphyo would be ideal, except that it is likely impossible (unless we're talking NASA-sized budgets).

That said, I think the Sylphyo internal sounds are great for a backup, and I even recorded a production track (and sometimes play live) with the SynthBrass sound. I always maintain a low-tech signal path from the Link audio out to my output system that requires no laptop support to access - easy switch-over in case of a Wintel crash.

@reidid789 A tool for configuration of the Sylphyo would be great, and it has been suggested and discussed before. (I can't immediately locate the discussion).

I think the issue is that sending any data upstream to the Sylphyo would be a big development project in the firmware ...

@wwoodard8 said in Double note:

Yes, dynamic.

Excellent that re-pairing the Sylphyo with the Link works!

I did want to comment on the use of the "Dynamic" setting for [MIDI Mapping] / [Velocity] parameter. This is off-topic for this thread, but important info, I think ...

In my experience, which matches the advice of Aodyo (in particular Laurent Pouillard from March 15, 2019) ... the Dynamic setting introduces unnecessary latency. The amount of latency is configurable (the [Capture delay] parameter) and defaults to 20msec (and 20msec is very very noticeable to me).

If you are using a sound rendering component (VST, hardware synth, soft synth) that was designed for a keyboard, it will likely rely on the transmitted Velocity value sent with each MIDI Note On message. However, if you are your sound rendering component was designed for a breath controller or wind synth (e.g. the Yamaha VL70-m hardware unit, the SWAM modelling engine, the Respiro VST, the Suonopuro sample libraries, a DynaSample module (XpressO, Xpression, XO-Mini) ... these components rely on MIDI CC messages - typically CC#2 (Breath Control) or CC#11 (Expression) - that follow the MIDI Note On message. In that case I set the Velocity value to 1. I have also played with other values in a few cases where I had some synth that needed velocity - and this did not seem to bother the sound rendering components that use Breath Control.

I hope this helps!

@wwoodard8 I would, first, simply turn the Link unit off and on. That has cleared up some issues with me in the past.

Second, I would re-pair the Link with the Sylphyo. This is a typical cure (for me) in a gig setting when communications suddenly gets flakey (or stops entirely) just before the gig. This is scary, but performing a re-pair has always worked in this situation. The scenario is that I set up long beforehand, do the sound check, and all is AOK. Then, as people arrive, I am thinking that cell traffic increases dramatically and that may interfere with the Sylphyo-Link radio connection. This has happened to me maybe four or five times in two years. A re-pair operation has always cured it. I actually have a label on my Link that says "Both Buttons to Re-Pair" just to remind me.

Failing that, I would reset (i.e. Factory Reset) the Sylphyo ... AFTER writing down all your settings so that they can be restored ...

Hope this helps!
