I like to use audio to modulate the cutoff of my 101 and micro. Taking the ring mod carrier out (set to hi freq, with the freq around 4 or 5 o'clock) and patch it into the cutoff (switch to 2pole mode so the carrier doesn't bleed thru) set the cutoff to about 7 or 8 o'clock, resonance set a little before it starts to feedback and this creates a nice talking effect ("Yow") or if I patch it to my micro filter I can create even more talking sounds depending on how the envelope responds ("Die" "yow" "ohh"). pretty cool sounding

Sending audio into the sweep in of the 103 can be fun too. 6 stages sweeping normally, the other 6 take on a sort of ring mod effect

"Oh Die Yow"

WTF?

Your micro has issues lolol.

One time I plugged my iPod's audio-out to my Voyager's pitch-in, and the only song I could really get to make a noticeable difference in pitch was a song off of the Fightclub soundtrack.

That's because the voltage level is not high enough. When I get a chance, I am going to see if I can use my amp head to create a strong enough voltage level (the same going into a speaker). I think this is safe as long as its below 5V but I get nervous with plugging things into the Voyager other the modules or foogers.

Hope you have a voltmeter handy. My Peavey puts 20 volts RMS into the speaker at full volume.

It's a small head I just use for experimental purposes so it should be pretty low votage compared to your Peavey.

My Peavey puts out maximum 50 watts. That's not much...well, by my standards, at least.

I guess if its to high I could step it down. I also don't know how well a voltmeter will measure audio voltage level. On other way to do this that I though of is using what is called an op amp. These circuts are simple. There are chips which do this with just a few other components.

I do find it interesting with the resurgence of interest in analogue synthesis that there is nothing to convert audio to a CV level of voltage. Perhaps there is from the modular makers but I have not seen it. There are MIDI to CV devices and CV to MIDI but nothing to move audio into the CV range of voltage level.

Another usefull application. What if the delay fooger worked with really short delay time, short enough to create flanging. Then, use an audio CV to modulate the delay. This is the type of out of the box thinking that I like to get into with foogers. I would also love to see Moog lower the minium delay time of the delay fooger but that is another topic.

I think the dot com instrument interface should be able to do this if im not mistaken.

EDIT: I just looked at the instrument interface again, I would think an easy although probably not the most accurate way to make sure you have the right out put would be to match it against the output level of the ringmod carrier out or freqbox osc out until the audio signal your trying to use as a modulator is at a similar level to the carrier/osc out. Plus this module would give you extra trigger/gate/envelope which is always fun

Your right.

Here it is:

This looks like Doepfer's version of the same thing:

This also has gates and envelope follower.
