Hi,
I found this great sounding Arduino based wave table synth by Nikolaj Mobius -
It looks as if Nikolaj focused on getting a lot of functionality into the synth -
Six Wavetables
Four envelope tables
Pitch modulation
I have been in contact with the group that Nikolaj is a member of and have set about converting the synth into a sound/music generation library with a more useable interface and friendlier naming conventions. There are some optimizations I have been able to make that have dramatically improved the ISR Perfromance as well - namely replacing the countless arrays with a single array of classes.
As I do not have an electronic music background but have learned a hell of a lot in the last six hours of reverse engineering, refactoring and testing I hope a lot of you will find this interesting and useful - I will probably publish it tomorrow or Sunday/Monday.
In the meantime, have a listen to the link.
