How to get random noise to serve as input for cutoff frequency?
« on: September 19, 2013, 07:49:42 pm »
I'm trying to get random cutoff frequencies to apply to a sound after a bit (a la the intro synth on Rush's "The Camera Eye") -- how do you do this with the SEM-V?

Is there no way to feed the subosc into the cutoff frequency? No sample/hold capability? I found a review that complimented the SEM-V's ability to do sample/hold, but couldn't find a reference to it in the manual.

Just saw this older post here, as I just joined    :)

I am thinking to use the 8-voice programmer set to vary the cutoff. It wouldn't be totally random though...let me check it out.

Besides the 8-voice part of it (cutoff set to a semi-random pattern,  and the direction set to Random), you also have to turn on the Arp or it wont work. I set the rate to 5.88 hz, Sync=Off, Mode=Up, Octave setting =1


I also added a  little of B2 reverb on this.

Ha! That's an awesome idea, and one I'd not thought of. It actually works, although it's a little hacky for an operation the SEM should be able to do innately and per-voice.
