MP-201 V2.0 Something interesting

Post by r05c03 » Mon Oct 26, 2009 3:28 pm

So, I finally figured out how to configure my 'Fooger rig to act as a mono synth controlled from my voyager. I was planning on controlling my LP simultaneously, setting it up to play the note played on the second key of Voyager and tuning my MF rig up a fifth so that I could play two keys but three notes. Follow?

So I set up the proper configuration in the Voyager and to my surprise, the MP-201 starts making the MF rig play at what ever second key I play. So if I am holding one key on the Voyager, the MP-201 causes the 'Fooger rig to play that note. If I then hold down a second key, the MP-201 causes the MF rig to play whatever that second note is.

Was this planned functionality? Because it sure is F'ing cool.

The MP-201 always uses "last-note" priority - meaning the MP-201 will play whatever is the most recent note you hold down, even if you are holding other notes also.

The Voyager on the other hand is configurable to have last-note, high-note, or low-note priority. It sounds like your Voyager might be set to low-note priority. In this case if you hold a note on the Voyager and then also hold a note higher on the Voyager keyboard, then the Voyager will keep playing the lower note but the MP201 will switch to the higher one.

If on the other hand you hold a note on the Voyager keyboard and then play a lower note, both the Voyager and the MP-201 rig would change to the new note.'

I think this is what's going on...

anyway, it's fun stuff, eh?

One thing that definitely IS planned functionality: You can set up multiple Midi-to-CV channels on the MP-201 and set each one to its own CV Scale to get proper pitch tracking... when you do this, it scales Pitch Bend amount also, so you can take two oscillators which track pitch differently from each other (say, one at 1.0 V/octave and one at 0.765 V/octave), and once you dial in the CV Scale the two oscillators will track key pitch and pitch bend in unison.

Something I've been enjoying lately is to set up something like this with 2 CV channels, and set them to different Glide rates... and set one pitch bend amount to +/- 1 Octave, and the other pitch bend amount to +/- 5 or 7 semitones. This creates some really cool pitch-bend harmonies, and the different Glide Rates create a really cool chorus or doubling effect while gliding between notes.

Good stuff! :)

Yes that makes sense. I think that is what is going on.

I am interested about this scaling thing. I figured out how to scale my Ring mod so that it tracks the the voyager keys. If I want it to play a note other than the key that I am holding down I set the frequency on the Ring Mod to say, 7 semitones above the root and I can play this "fifth" chord all up and down the keyboard with only one key.

...but that is not what you are describing, am I right? I thought the scaling was just to be able to fine tune the correct voltage steps so that one the VCO tracked the MIDI notes. How again are you using it?

R05c03 - I like what you're describing, too. I'm talking about setting the Pitch Bend Amount differently on the Voyager vs. the MP-201. That way if you hold a note where the Voyager and your Ring Mod are in unison, then do a pitch bend, the V and the RingMod will bend up from unison to a nice interval.

You could combine the two and have parallel 5ths which pitch-bend into an octave and a fourth, say... all kinds of nutty combinations are possible! :)

That interval pitch glide is the Bee's Knees.

Also, I was thinking it would be pretty easy to make an LFO increase its speed with each note played by feeding a MIDI-CV channel to its rate.

Jeez so much experimentation to do, so little time...

Yes, that's cool. It's one of my favorite things when I midi-to-CV to my OS Voyager. Think also of the CP-251's 4 way multiple to send a CV to more than one destination, and/or the mixers inverting output, to get inverted CV (negative voltage) so that you can reach pitch lower than the starting note at 0 volts. Acts like a reverse keyboard actually 8)
