Long time since I did anything with an Arduino, but I have the urge to finish a synth I started last December.
I have an existing arduino 5 dollar keyboard synth and also a stylophone with the guts removed.
Question is which to base the new project on ?
This is a quick demo of the filter http://www.youtube.com/watch?v=k-hOPo6zwwE
and this is a quick demo of the five dollar keyboard, the new project will include the filter, arp etc etc from both projects its just a question of whether more people would build a donor keyboard version or a donor stylophone version ?
Basic version with Arp http://www.youtube.com/watch?v=yQsgIRSDGm0
Dual oscillator and delay added http://www.youtube.com/watch?v=ZuKoG15oObk
