Midi/CV converter into Moog S-trig

Post by ColorForm2113 » Mon Jul 16, 2007 3:37 am

I was looking at this Midi/Cv converter on Ebay and i was wondering if anyone knows if my plan would work...
I want to run the midi out of my Electribe in to the converter then the Cv out in to the S-trig input so that the sequenced notes on my electribe would be played on my MicroMoog

Any input on this would be great! Thanks

I thought s-trig was a gate signal/connector... not CV. Also, I think the micromoogs cv scaling might be slightly off of v/oct IIRC?

The problem with the micromoog is that it is not 1 v/oct like most synths. If you have a midi to cv converter that allows you to get around that you should be okay. You will need two cables the cinch-jones cable for the gate and another for the pitch cv.

Just sticking a cinch jones cable into a gate jack wont work though I dont think, either. S-trig maintains a voltage then drops to 0 for "on" state, where it is the other way around for gate.

I assume that ColorForm2113 is looking at the midi to cv converter someone is selling specifically for the micromoog. But you are right, Moog trigger works differently than Roland and others.

By the way, has anyone bough any of the converters from http://www.dinsync.com/ I think it is the same guy selling on e bay.

oh wow, ididnt realize that it wasnt 1v/oct. (yeah manual says .95v/oct..weird..) ive hooked it up with my Moogers no problem though.

i do have the cinch jones for the gate. where can i find a pitch/cv cable.

if it isnt dead on 1v/oct could it do damage to the synth or pedals when i connect my moog to my MF's?

thanks a bunch everyone

do you think it would work better putting the midi/cv into the osc input and either putting it on bypass , or just hold down a key and use it like an arpeggiator?

Converting a normal gate output to S-trig is straightforward, but made up leads are available on ebay if you can't be arsed.

Well you could always use/make an attenuator for the .95v/oct thing.
The Frostwave MC1 can be scaled internally with a screwdriver, but takes time to get right.
Most CV converters these days cater for v & s-trig .

ColorForm2113, you are not going to hurt the synth with a converter that is 1 v/oct it will just pay out of tune. You can make a voltage divider from a few components t0 make a 1 v/oct converter work for your micromoog. Here's a link for plans http://www.nabble.com/Fw:-Micromoog-t208966.html

Most midi to cv converters include both a gate and cv output, enough to give you note on and off and pitch. The cv cable is just a regular 1/4 inch cable.

You should read up on cv so that you know what you are getting into.

I can't get this to work with my MG-1 or the Source. Maybe it's something with my Doepfer MCV-4. It has turned me off from using Moogs.

As far as the orginal post: Just get this thing:

It does it all and will switch between all the CV/Gate formats

I think most modern MIDI/CV converters have an S-trig option on the trigger outputs. At least the one in my Analogue Systems modular system does.
Moog also uses 1.02V/Oct instead of 1V/octave, so you might have problems with pitch drifting slightly along the keyboard. The AS module fixes that aswell.
