Having implemented a great and very fast algorithm that makes the CNY70 response linear I give you a new recording of an old piece that now sounds quite great:
Before I wrote, or to be honest I let write by another program that I wrote, the code for the CNY70 linearisation I implemented and tested the polyphonic aftertouch feature about which I will definitely report next time.
P.S.: I’m still wondering what piece I should take to demonstrate polyphonic aftertouch. Besides my capabilities on playing with it are not quite developed 😉
