Does anybody know if the MF101 Low Pass Filter’s ENV OUT jack fuctions as a gate/trig to trigger the envelope on other synths with such inputs?
If anyone has this type of set-up (MF101 + Synth with gate or trig in) and could try it out, I’d love to know.
I’ve thought about replacing my MS20, but I really like triggering it with ext. audio signals, and can’t do this with any of my other synths. But, if the MF101’s ENV OUT will trigger the VCA of another synth, this would be a good alternative.
Although the synth, of course, wouldn’t follow the pitch of the ext signal (from the 101), I’m hoping it will at least open the VCA and play whatever note I happen to have last played from the synth keyboard.
Anybody?
Good question.
I just tried this:
Audio out of my Voyager to the 101 filter. ENV Out of the 101 to the +5 Gate on my MacBeth Moroco.
It DID indeed work to trigger the Envelopes on the Moroco.
So to answer you question, YES the ENV out of the MOOG 101 LPF can be used to trigger a gate.
Thanks, you’re awesome!!
One question though, did it just trigger the filter envelope, or did it open up the VCA and play a note on the synth?
Sorry, I realized as I was re-reading my reply that I was not too clear.
It did open up the VCA, so sound could go through.
I’m sure it’s supposed to be the envelope follower output otherwise it would be called “Gate Out”.
That said, because we are dealing with voltage, the envelope follower output probably is hot enough to give you gate-like results depending on the gate threshhold of whatever you’ve plugged it into. To be serious about it I’d recomend processing it furtrher, for instance with a comparator.
Some envelopes get triggered by a fairly low voltage. Some need lots of voltage (some Rolands want +15v), some want a specific sort of trigger like the early Moog’s S-Trig standard
If you want to very literally replace your “MS-20”, as you might know, on the MS-20 you get a bunch of voltage outputs for instance an MS style gate, frequency to voltage and an envelope followed signal.
