"Use track sounds" is truly wonderful.
This is where performance mode shines.
I prefer making performance macros that invert values of one sound while promoting another. This is great for morphing.
For instance, Performance A adds filter envelope amount of Track 1 while reducing filter envelope amount of Track 2.
Or Performance B brings Reverb send up on Track 2 while reducing on all others.
Adding decay to one while reducing the others... etc.
Adding delay send + chorus for one while reducing on all the others and also changing delay timing and frequency filtering (do one performance assignment like this for each track and it is close to having individual delay for each track, but you only get one at a time.)
And on Analog Keys, using the joystick assignments in this way is a ton of fun.
Complex modular-esque beast mode, indeed.
No other synth is fun in this way.
