I tried something kind of cool the other day that I thought you folks might be interested in. Ingredients: Voyager (with VX expansion), CP251, lowpass filter, guitar. Apologies if this has been discussed previously.
So here’s the idea: random cutoff modulation following a MIDI tempo. Send a constant series of notes at whatever interval you want from computer to Voyager. Then send Voyager gate out to S/H trigger in on the CP-251. Then send the S/H signal to an attenuator and then to the cutoff in on a filter (I suppose you could just use the Voyager’s own filter for this too, if you don’t have the pedal). Play guitar through the filter and voila.
What it sounds like: every quarter note (for example), in time with a song you’re working on, the frequency cutoff will randomly change and be held until the next note. Also cool if you mix S/H signal with a fast LFO to warble that cutoff rate a bit. The result is something like what the MURF sounds like, but more unpredictable and out of control. Layer the same performance with different cutoff mods a few times and get very interesting, complicated results.
Would work fine with ring mod or freqbox frequency or many others too, of course.
My tune isn’t done yet, otherwise I’d post an example. Enjoy!
If I understand what you are describing correctly, then another way to get there is with the MP-201 and the low pass filter, as the MP-201 will sync to a clock and output a S+H signal. I use that control signal a lot.
Brilliant! I’m sure I’ve tried something like this before, but I’ll revisit it using different input signals, substituting Voyager with LP, and filter with wah. Very cool!
Thx. I’ve used a patch thats close to this however, the source for the one I’ve used was Roger Powell’s patchbook for the Mk 1 ARP Odyssey.
He used the keyboard gate to trigger the s&h to create smoothed cv variations.
One of the his patches also used the kb gate triggered s&h to vary osc2 pitch in a synced pair to produce timbral changes.
Good stuff !
Bryan T - that’s exactly right. I was thinking “boy I need an MP-201” and then tried to figure out a way to get the some of the same effects, with marginal success. You could also use slewed pitch CV from the voyager to create sine or other waveforms, I suppose. Not that this has dulled my “need!” for the MP-201, of course.
LWG - yes sir! I’ve tried the same configuration, but S/H signal to Voyager filter in, and just play the Voyager. Every time you put a key down the cutoff will change randomly (really weird results if you don’t attenuate the S/H signal much). It’s very cool if you sync Osc 2 and use the S/H to modulate its pitch.
