I had the same issue hen I first got mine and yes I too sorted it by changing the thumb size. I have set mine so that to pitch bend down I just roll my thumb down from where I naturally have it at the thumb rest of the instrument. Then if I want to pitch bend a note upward I start the note with my thumb in the roll down position and roll it back up to the thumb rest of the instrument. This seems to work well although sometimes the slider seems to loose its start setting and the pitch bend only works halfway down the slider. When this happens I lift all fingers off the sylphyo for a few seconds at the first opportunity, then carry on playing. This seems to recalibrate the setting and all is good again.

I’ve just got my Sylphyo back and I was playing it earlier but it seem to be dead now. The light on the link turn green but the Sylphyo has no life . And I have a gig tomorrow

Out of interest, what style of patches are you looking to include inthe link? ie, emulating instrument sounds, pads, synth?

Sorry fella I haven’t been on in a wee while so didn’t see your reply, but I’ll try and help where I can. Firstly let me say that my XV2020 has the patchman sound bank in it so I do tend to use the breath control. Unfortunately I don’t have the ability to look at my Roland settings as I’ve no computer that’s compatible with the editor for it. I regards to the BC there’s also the options tab in the Sylphyo that will also send different cc’s for volume but I tend to find it affects how the patches sound so I just stick with BC. It’ll be something to do with the settings in the Roland probably. But apart from that I’ll try and run through I’ve got the rest of the Sylphyo set up just now.
Midi mapping;
Breath>
Minimum =500
Range =2500
Curve =linear

Keys>
Fingering =saxophone
Reaction time =50ms
More sensitive =unchecked
Key bend =unchecked
Key noise =unchecked

Slider>
Function> pitch-bend + - = checked
Top edge> pitch bend -
Bottom edge> pitchbend +
Thumb size = 20

Movement>
Shake to move = on
Shake to vibrato = on
Elevation control =off
Roll control =off

I also tend to restrict the hole at the bell to more create what I’m used to with the sax by using a pipe cleaner as they soak up the moisture and cheap to replace. https://www.hobbycraft.co.uk/assorted-pipe-cleaners-100-pack/570321-1000?glCountry=GB&gclid=EAIaIQobChMIw8ba2bmF2QIV4r3tCh3bkQNDEAQYBCABEgKaI_D_BwE&gclsrc=aw.ds

I also use a Roland (xv2020) with the patch an patches. There’s always some on fleabay for around £120 and then just get the patches from patch man . If you can though I’d go for the Roland xv5050.

Good morning guys. I’ve experienced this issue also after I updated to the latest os. I contacted the guys at aodyo back in July last year and they suggested decreasing the breath rate in the midi mapping section. Since then it’s been much improved . Ps I use a hardware synth (Roland xv2020).

I’ve had this Sylphyo now for a couple of months and really like it and I look forward to the sound card and active mouth piece. But I do have a wee issue where the notes stick (hang). For example I may play a c3 but then nothing below this will play, I can play notes above it but note below. Any ideas?
