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:

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

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".
