Envelope FOllower of the 101/107

Post by EricK » Sun Mar 02, 2008 4:02 pm

If I wanted to externalize the envelope of the 107, how would I have to patch it to control the rate of another LFO or something else?

THanks,

Env Out of FreqBox to whatever input is appropriate that you wish to control.
Minimoog Voyager Performer Edition + LP Stage II + Sub37 + Model D reissue + CP-251 + VX-351

You can just take the Env out from one of those and patch it into whatever CV you want to modulate. In my experience attenuation isn't necessary, although if the sweep you are getting is too extreme then you can do that. It can also be fun to invert the Env signal with the CP-251 (take the Env out CV and put it into the Mixer, then use the -ve mixer output to whatever you are modulating).

So for example, just take the Env Out from the 101 or 107, and patch it to the Pedal In on the CP-251 LFO. This will cause the CP-251 LFO to speed up and slow down with your dynamics. Or another example, which is one of my favourites, is to take the 101 Env out, invert it with the CP-251, and put that back into the Cutoff jack on the 101. So now you have inverted auto-wah. To make this sound good, you'll need to lower the Cutoff knob on the 101 quite a bit, to give it something low to sweep down to.

I thought I tried that....hmmm.

Im trying to increase the freq on the 102 with the envelope follower on the 107.

also im trying to use it for increasing the delay time, but Im wondering doesn't something have to be connected to the freq audio in to activate the envelope follower?

Lets say I just want clean tone with tremelo from the 102 with the LFO rate effected by the env follower. Something is either not becomming an audio signal or the env isn't changing anything.

lolol im doing okay with the complicated patches but for some reason the easy stuff is giving me crap lol.

THanks for the tips so far!

I've used the envelope out from the 107 as an audio source with very cool results.

May not be super useful for this particular thread, but I'm throwing it out there anyhow.

I figured it out but I had to run the audio signal to the multiple and then to the Freq Box input, env out to freq input on 102, with the second audio going to the 102.

Did I overcomplicate things lolol?

Hmm. I don't have a 107, but I do have the Low Pass Filter, which has an envelope follower. If I were trying to do what you're doing, I'd plug an instrument into the LPF, the LPF into the 102, and then to my amp. The only CV needed would be from the LPF envelope out into the Frequency in on the 102. The LPF does not have to switched on - the envelope follower is active when the LPF is bypassed. I'm not sure if the 107 works that way.


A wonderful, wonderful, wonderful thing to do with the envelope follower is to use it as the trigger for the sample and hold filter on the CP-251. Whenever your audio signal gets loud enough the S/H will spit out a new random voltage. You can use it to randomize ring mod frequency, low pass filter frequency, delay time (or feedback), or plenty of other things. It adds a randomness that you can control with your attack. I can't wait to try it with a drum machine or a drum track.

Another way to do it more simply would be to connect all the units in series, and leave them active, but turn the Mix controls to completely dry for any that you don't want to hear effecting the sound. That way the envelope follower is guaranteed to be sending CV, but you won't hear anything you don't want to hear.

Jeez lololololoo

You know I wonder if someone has actually calculated the amount of things possible with these units. (Infinite?)

THanks for all your help!
