I made this patch which uses the solo-synth of the G1 as Oscillator Shaper. This is done by creating you're synth sound shape with the envelopes , filters etc but you zero down the volume for each of the five oscilators or which one currently used and save that file. 

In the performance zone one gets the Oscillator Shaper synth and zone 2 and 3 gets any sound that will be shaped by zone 1. 

And this is how it sounds. The G1 can do wicked stuff I'm on half of its 
possibility's plus I'm learning how to work with synths without a computer.
