Korg ms 20 cv control

Is it possible for Reaktor to act as a squencer for a anologue korg ms20.
What I mean is can you get Reaktor to convert midi data to control voltage and gate data. Any one have any ideas? would grateful for any suggestions

 

it is possible but i think you will need a korg analogue interface,
or else do some maths in reaktor.

reaktor is closer to the 'roland' 1 volt per octave system. korg uses (i think) 2.5 volts/octave. the korg also uses 'S trigger' for it's gating. that is basically opposite to the roland gate system.

btw, there is a fantastic korg ms 20 emulation in the user library by solar x.

You cannot use your soundcard to output CV due to hardware design of the soundcard - see this thread..

You pretty much need a midi->cv interface. You could get rekator to do the math so that a midi->cv that runs in "normal" 1v/oct mode mode could be used to control an ms-20 that uses Korg's v/Hz CV mode.

i have often used an audio out from a motu 828 to send audio table curves to modulate the filter cutoff of a sequential pro-1, or the cutoff of a sherman filterbank via the fm input. as long as you are dealing with something that wants a voltage between -1 & 1 it works reasonably well. for precision pitch sequencing you would need a dedicated hardware converter.

 

I'd be very surprised if it worked with *steady* values - liek a Pictch or Gate CV.

That is DC and not AC signals. If yo pin the output to +1v, does it stay that way on the modular side, or does it slowly drop back to 0 on the analog output?

If you're modulating something with a rising and falling (AC) signal you should be fine - though the High-pass filters built into the output circuits may make modulation by slow-moving LFOs not work 100%.

thanks for all your replies, it looks like i'll have to go out and buy a midi to c.v. converter. does anyone know of a site that i can go to find out more information on c.v and gate theory.

thanks again

 

google??

I use their Kenton Pro Solo to control an ms20 with midi coming from my pc.
