Cool idea.
I'm wondering if it would be feasible to make an option to disable the original DCOs and use the new ones, and have another option to have all DCOs on (old and new 4 OSC)???
Also I like the idea to maybe have one original DCO ( so we had 8 note polyphony ) and then and one or two new Oscillators. Total of two or three? Or maybe the two new OSCs will be able to do 8 note polyphony?
I have no idea how to do this, or what can be achieved. Just throwing out ideas....

I am not looking to spend much time on this. But I really would like to expand the Poly sound capabilities at the beginning of sound path.
