In the latest release we've been doing some of the groundwork to make the finger vibrato possible in the future. Not everything is ready for it, but we've been making progress in that direction.

Yes, it's always good to share knowledge!

Don't set your expectations too high! This is not an acoustic instrument, and the academic and technical understanding of what makes the sound of an instrument so unique to its performer is nowhere near complete. So it won't be at the level of a sax, but we feel the Sylphyo still has something special in this regard and we're working towards making our internal sounds even more unique and versatile. Certainly, we're already amazed when we see other artists appropriate some of our sounds and make them sound veeery different just because they are different persons. It also depends on the sounds, some are more "fixed" and others are designed to be more "versatile". Personally, I find that it's very easy with the Sylphyo to incorporate the different ways to articulate and modulate sound into my playing (vibratos, tonguing techniques, bends, etc.). And if you pair the many expressive controls of the Sylphyo with an awesome physical modelling synth like Respiro, well, that's a killer match!

As for the fingerings, if you come from the saxophone, you'll find that there'll be a period of learning to compensate for the missing keys. It's something we want to address (e.g., making a B flat by half-fingering the B key or by fingering the B key and half-fingering the A key as you suggested; or having alternatives for the palm keys) but we're not there yet (we're very open to discuss the fingerings with users). If you have experience with other wind instruments you might want to try the different adaptations we made for their fingerings, and select the one you're the most familiar with.

We don't have many Linux users, and we don't officially support Linux as a platform (it might be a problem for applying updates, though they work great in a Windows VM), but the Sylphyo and Link are USB-MIDI class compliant so everything will work great with your existing stuff. Please feel free to report on your experiences with Linux!

Pour annuler le glide, on peut toucher le bord bas du slider avec le pouce, remonter le pouce un petit peu et le redescendre jusqu'à dépasser le bord du slider. L'important est de commencer le mouvement depuis le bord bas du slider, pas depuis un autre endroit.

What did you hope to use the mouthpiece for? The Sylphyo has evolved a lot in two years. Have you tried shake vibrato and doing pitch-bends using the slider?

As our mouthpiece project is still in the research phase, it is best not to expect it in the near future, sorry. For now our development focus in on an editor for the internal sounds.

We have had another report of this issue but haven't had enough returns to determine if there are particular settings that aggravate or mitigate the issue. Do you have an XpressO? If so, a trace from a MIDI monitor utility demonstrating the double notes would be very helpful.

Beaucoup de gens utilisent les 2 octaves supplémentaires, ce qui est déjà plus confortable.
Si vous souhaitez essayer une version bêta qui permet d'avoir le système qui était disponible avant (9 octaves en tout, au moins 5 si vous n'utilisez que les trois touches d'octave), n'hésitez pas à nous envoyer un petit mail à support@aodyo.com !

C'est une fonction qui n'est plus officiellement présente depuis la version 1.0.0 ! Nous l'avions retirée car elle était difficile à utiliser de manière fiable, mais nous pourrions envisager de la remettre en "version bêta" par exemple…

The latency thing is something we cannot reproduce.
Could you please confirm that it is still there even after a factory reset?

If it's still there, the usual thing to do for diagnostics is to use MIDI monitor software and try to see if there is a significant delay between an action on the controller and new data being displayed on the screen. It would be very helpful if you could test your Sylphyo+Link using a MIDI monitor (see this article for help), ideally showing us a video of the delay.

Did you try the official 1.3.1 version from our website as well? There are some differences compared to 1.3.1b2.
