Well, I'll admit it has great modulation capabilities. I should take another look at it...at first glance it seemed to me like it was an FM synth that was trying to do physical modelling, but perhaps because of its architecture it can do things that neither Six-String nor a standard FM synth can do. I probably judged it too quickly.
There were some technical issues I had with it, though. The Env3 nodes were really slow trying to move them around, the Python Mod patch spit out 0db noise at one point, and the Python Pro made my computer lock up. (I have a PC with XP.) I got rather nervous using it and gave up after a few minutes. I guess I should have another look at it.
Well, I think John Bowen is doing some great stuff, and I am really looking forward to 3.1 updates for his synths!
