I don't expect it to be an elegant FX processor, I just want to add another feedback loop around it (and the fixed delay is not a problem, it just makes it more interesting...)
I may be wrong, but it seems an input wouldn't be too much coding?
It's a little rough as a solo instrument, but using it as an oscillator in a subtractive synth patch, it adds a bunch of life and interest to all kinds of other sounds.
