In the sound menu of the Sylphyo, after the "regular" sounds, the list repeats itself with names with a ° (degree) sign in front.

Is there something we should know about these duplicates or do we just ignore them?

So far I've seen this is not possible with the Sylphyo alone. Needs MIDI processing.

The elevation angle tells how much the Sylhpyo's bell is lower than the mouthpiece. Horizontal is 0° and only there you get 127. Fully down is 90°. When you have the elevation setting at 35° and start playing fully down, nothing happens until you reach 35°. From that point you get 1-127 until you reach the horizontal position (0°).

I would prefer from-to degree settings, where we can set an arbitrary range instead of dealing with given endpoints. But as a newcomer I don't dare to send two feature requests on the same day ;-)

I do not use Kontakt but this is sophisticated software. It should have something like input curves or other ways to scale input data.

If Kontakt cannot do it, maybe your DAW can. Which DAW do you use?

@Clint
The bank setting let's you select a sound bank number (for synths who require that) but afterwards it also sends the Program Change.

I see what you mean and it is somehow similar to what I do. Below is a draft of my smallest computerless setup (not tested yet).

The controller has 2 MIDI outlets that can be filtered by channel. For each sound change I send first the Sylphyo PC (which sets the 'wrong' Blofeld program) and after a short delay I send the Blofeld PC I want. The Gordius can do this automatically. This way I get one dedicated sound combination with a single footstep.

Manipulating the Sylphyo settings will still 'unset' the Blofeld program but I don't see a way to avoid this as long as the Sylphyo sends Program Changes. I could add a hardware MIDI filter after the Sylphyo but this adds another box and may cost additional 100 Euro or more.

Checked again and disabled the Sylphyo's movement CCs. Really cannot tell what is going on. Stuck notes, changing/losing the Sylphyo's internal sound (I mix with the Link's stereo input) and weird behavior overall. Turned everything off and on in different order – no change. Turned everything off, went back to direct MIDI connection and it worked fine.

Never mind. I believe some devilish ghost in a parallel universe prevents me from using USB hosts. A Keith McMillen host did not work here. A Kenton USB host didn't. Why should the Link do. I blame the ghost ;-)

MIDI over DIN works well, I will use this.

A shy feature request:
Could you please think about an option to block outgoing Program Changes in the Sylphyo?

The Sylphyo outputs PC at various occasions and often switches the other synth to some program it should not be. In my case I want to change the sound of both independently. Of course in other setups you want the programs strictly linked. Therefore the setting must be optional.

Blofeld Desktop.
It accepts anything. Notes, Pitch Bend, Program Change, most Control
Changes, Channel Pressure, Poly Pressure, SysEx and MIDI Clock.

@support_aodyo Yes, I think I was too early with narrow thumb space. It takes a while to handle that.

Is it possible to configure the Link's MIDI output as Out/Thru?

Would be fine for hardware synths, when the Link could merge incoming data with Sylphyo data at the output.

Two Sylphyo questions.

——————————
Menu page "Movement", last setting: "Always on"
I wanted to use "Always on" for Roll and Compass control (MIDI out). But the function only works when the "Absolute" setting is ON. Is this intentional? The manual doesn't mention a dependency.
——————————
Main menu page, Wireless: "LED"
What is the "LED" setting supposed to do? The light on the Link box does not change.
——————————

I see that Compass control is in beta stage, so the following bug may already be known:

Rolling my Sylphyo more than about 45° to the side makes the compass (!) control jump to the min or max value, depending on the roll direction. Rolling to the right side kicks the Compass value to the lowest position and vice versa. I can reliably reproduce this by monitoring the MIDI data in Max.

It happens
... in a sensor-friendly playing position (Sylphyo horizontally)
... in all Roll modes (standard, bidirectional, absolute)
... with all Roll degree settings (5°–90°)

We can work around the problem by avoiding large degree values and/or extreme roll movements. But since one parameter (roll) triggers another parameter (compass) so hard, I thought you may want to know about it.
