@support_aodyo I would be interested to know whether Aodyo has ever performed HAST stress testing on the Sylphyo. In my opinion (as an engineer), moisture is the most likely candidate. If I play for over, say, an hour with a completely dry sylphyo I will start having octave issues eventually during the playing session.

@clint The more I think about this last response of yours, the more I'm coming to the conclusion that the octave sticking issues discussed elsewhere are moisture-driven. Software updates don't seem to fix the problem, and I've noticed it happening well into a playing session or the next day.

I've been using the pad saver because it wicks moisture, but maybe I need to experiment with leaving the sylphyo out and letting the dry Arizona air do its work.

I may do a DOE on this.

@join I must completely remove all my fingers from the pads and stop blowing in order to get it to stop playing the wrong note.

@support_aodyo Sorry for the long wait. Yes, it still occurs with 5 octave mode. I have not tried the other modes. Franky I have never been able to figure out how to work the 5+2, or at least what the manual describes doesn't seem to work for me. I don't see any difference between the 5+5 and 5 octave modes.

I am still experiencing this problem with the update that dropped within the past couple of weeks. I have always used the internal sounds and have not tried it as a midi controller yet, but that's becoming a priority for me, so I'll have some data there sometime soon.

@clint It seems rather elaborate. I just use one of these Rico clarinet pad guards to first swab out then it leave inside the bore of the instrument. You get two, one for each half of a clarinet. I use one as a spare. I don't see a need for a fan, but then, I live in Arizona and dry air isn't all that hard to find here.

I'm getting a delay using phi flute setting through link into an amp. I'm trying to learn some of Ian Anderson's flute parts in a couple of Jethro Tull songs, and his staccato style is totally unplayable due to the delay, which is as long as half a second.

@support_aodyo Point of order here. In English, if you say "repair" it means to fix something that is broken. What you mean here is re-pair, as in pair again.

I had a similar issue discussed below. The latest software update and the suggestions seem to have fixed it, but I haven't played much since then due to some health problems that I'm now recovered from. Hopefully will be playing more now. See if what you see now is what I describe in this link:

I'm a clarinet player but I'm not really happy with clarinet fingerings on sylphyo. There are too many alternate fingerings that don't work on sylphyo, and I end up not getting what I want. That and clarinet breaks in twelfth instead of octaves. Basically, sylphyo isn't really built for clarinet fingerings.

Anyone have suggestions on what a reasonable different fingering map would be a good alternative for me? (I don't want it to be sax.)

Updating the software to the latest version seems to have fixed the issue. I have not experienced the problem, though I must confess I haven't play much since the original post.
