And it is an octave higher. Very similar to a recent discussion on synth-diy. Of course, now I want VC of the switch threshold on the 700. ----------- LH responds: OK, I just tried this. Cool. However, I did not get the octave up thing. Try this with +5 volts. MUCH more interesting in my opinion. BTW, my suggestion for mixing another CV with your CV-IN of the 700 works to control the threshold just as I thought. Now, use the follow inputs to that mix: 1 - LFO - gives you LFO speed PWM of your saw/pulse wave 2 - EG - gives you a wave that migrates over time. 3 - Audio from another VCO (higher freq) - S**T this is wicked. You get the audio of the second oscillator appearing on the other wave just at the edge of the pulse, almost in a carrier like fashion. Sweep it and it is kind of like hard sync, but not. Larry
