Nice project, similar to REMI EWI. But did you find the pressure sensor good enough for the task? Wasn't the range of the sensor too high for human breath? I think that maybe MP3V5004GP or ABPLLND060MGAA3 might be more appropriate, although they are pricey and not that easy to find. I want to create something similar but with position sensitive strip (so called softpot) - it might make fingering more interesting with glissandos and without complex fingering patterns to learn. Just slide your finger up until you reach the note, and with time you might develop muscle memory for how far to slide to reach the desired note. Considering that we have total control over MIDI signals, we might use proper quantization and also learning mode where the note sounds really quiet until you slide to the desired note and then stop for more than 100ms or so - thus you will hear some low volume feedback while sliding and then when you feel like you've found the right note, you just stop sliding and the note sounds as loud as you blow it. Or you can split the strip in virtual sections marked with some rubber lines to make each note distinct. Of course, classic woodwind fingerings wouldn't work because the softpot doesn't support multitouch. Anyway, lots of possibilities with both softpot, touch sensors or even physical buttons for those who want more saxophone-like feel.

Very cool, Gwen. Is your code available anywhere?
