The multitouch trackpad on a macbook pro [1] feels very consistent.
This is key for an instrument. It can be as responsive as you want,
but if it's not consistent you can't play it automatically. I found
an existing
trackpad synth, but it wouldn't let me change the note selection
interface. So I wrote one. It's still very much alpha, but the
code is on
github. It's four octaves, diatonic, but that is adjustible in
the code.
It works by slightly extending some multitouch sample code to output SKINI which I'm using the Stanford Synthesis Toolkit to turn into audio. My next target is polyphony.
[1] which I now have for my new
job.
