I people, I want to know if anyone as tried ou Silent way with the korg Ms20 series. I know that with volta it has some isues i think because The MS-20 VCO CV input doesn't respond to bipolar voltages. It has a range of 0-8V, while MOTU interfaces have a range of about -4 to +4. Even if you only wanted to use half the range, the 0-4V range is so low pitched that pitch calibration doesn't work. So you have to add in an offset voltage. I dont have a motu around so I can test it, but I will get one with this works on a Ms20.

By the way somebody told me this would work with volta

"The easiest way to do this is to add a ramp source and set the ramp to a constant value of about 0.6 to 0.75. The ramp and your voice pitch CVs will sum so your effective output will be 0to8V instead of -4to+4V. Then you can adjust the VCO scale and pitch knobs to get the base pitch into the range in which calibration will work. The calibration mode has to be set to Hz/V."

Hope this helps somebody

give it a test and let me know Thanks guys

In this thread there's a user who eventually got his MS-20 working with Silent Way:

Agreed, I don't believe the Ultralite mk2 exists.

And agreed about that ramp thing. If the hardware will only output 4V, nothing you do in software will change that.

I managed to get the Yamaha CS-30 running just fine over 67 octaves. This uses the same hz/volts that the Korg MS10/20 uses.

Couldn't get it to calibrate using Volta. Mess around with the oscilator i.e take off some of the filter so it can track easier to calibrate, try different wave forms.

Also use the headphone outputs as these put out a much higher voltage.

doh! lol I meant 6 to 7 octaves Dead Banana

I just got the MS-20 working perfectly with Silent Way Voice Controller AU 1.4.0 G5 dual 2.5, OSX 10.4.11, DP 5.13, 424 card/24i/o > Synthesizers.com signal processor to add about 4V positive offset>MS-20. Didn't chart the octaves, but hey it works!!
Good job Expert Sleepers!
applause

Still haven't got Volta going with the MS-20 but will try again sometime soon.
Now I want to take a break testing and make music.
Or whatever we're calling these blippy noises.
I like to call my stuff 'pieces'.
That's pretty all encompassing considering that it covers 'pieces of shit' on up the scale.

Awesome - thanks for testing and for the detailed results.

You'd more than qualify for the bounty by the way.

I got my MS20 going with my Motu 828 mk1 as follows:

(after maybe 2 days of pulling my hair out and refusing to accept it doesnt calibrate without a voltage offset!!!! : )

I used 2 insert Y-leads and plugged into outputs 7-8 (the others didnt work)

output 7 goes into the the 'FREQ' input of the ms20, which takes -5v - +5v, you need to set your EG1/EXT knob to 10

(I used the black end of the Y leads for connections)

output 8 goes into trigger, again using the black end of the Y- lead.

i used only OSC 2 and set it to 4' and triangle wave

AND BELIEVE IT OR NOT! I GET OVER 6 OCTAVES!!! YAY!!!!!

having much fun now smile
