Playing to the strengths of the P2 will get me to save patches.
- Paraphony is king in this synth. Try assigning 4 different waveshapes to the oscillators in Paraphonic mode. Test the differences between normal VCA operation and holding the VCA open with a DC offset, both ways can be useful. Set the Filter Env amount to zero and modulate it with other things instead.
- Modulation sequencing. You can have the sequencer running all kinds of background modulation, yet not triggering any notes from Track 1. Playing notes free-hand against the sequencer's modulation is a nice trick.
- Feedback. Often unpredictable. Playing with this usually makes me save patches because I stumble upon something I know I probably couldn't recreate if I tried.
- External Audio Input rocks. Sometimes I approach the Pro 2 like this: it has two analog filters (series or parallel), an envelope follower, a digital Character section, feedback, delays and distortion, tons of modulation sources and routings, a 32-step multitrack sequencer, CV ins/outs for external gear, all housed in a box with lots of knobs and 44 keys. Oh, wait, it has internal oscillators too? Cool, I guess those might come in handy sometimes.
