Re: [motm] 700 modulations

2000-07-30 by J. Larry Hendry

I have a little 5 sec mpeg file of this effect showing the scope and hearing
the wave if anyone would like to see what Tomy's idea produces.  I added the
audio in a modulation.  Very cool.  The file is about 200K.  I thought maybe
a bit big to post to the list.

Just toying with waveform mangling. With a ramp into both the CV and A
inputs on a 700, and -5 into the B input, I get a waveform whose positive
is ramp and negative is square or pulse. 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.

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.
