Title: MB new best friend Korg MS-20 mini
Post by: joja_x on January 28, 2013, 10:58:08 am: Happy owner of the Minibrute which Im enjoying very much :) I will get the Korg ms20 mini and was hoping to use some of the functions from the MS20 patch board to control the MB. Since Im quite new with all this CV stuff I wanted to hear from the pros if there is anything I should be aware of connecting the MB with the MS20?

Like 5 volt should be ok to feed the CV filter on the MB?

Post by: beefinator on May 20, 2013, 10:08:28 pm: think I saw somewhere that all the minibrute inputs are good up to 10V.

Post by: matias_thinKing on June 06, 2013, 05:13:35 pm: yes I asked about this, and the mb has 10v rails. iirc, the ms20 has bipolar -5v to 5v rails. You'll need a utility module to make either the mb cv signal bipolar or to make the ms20 not bipolar. luckily as they both fit a total of 10v of space, I don't believe it should be more complicated than this.

Post by: beefinator on June 09, 2013, 12:47:47 am: It would be risky without more specific info, but if the minibrute inputs are differential, floating with respect to ground, you could hack together a CV cable where the sleeve connection, normally to ground, was actually connected to the ms20's -5V rail, giving a 0-10V CV range.
probably not though, I dunno.

Post by: matias_thinKing on June 27, 2013, 02:22:34 am: The ms20 takes hz/v in, not v/oct. you may find more information under the "earlier tips" section in this webpage - http://www.gotart.fr/bward/korgms/mstt.html

I read it this " [/size]Another view on the MS-20 in OCT/V mode -
As some of you may already know, the MS-20 can work in OCT/V mode. Use the VCO input instead of CV in. Adjust the potentiometer (VCO section, EG1/EXT) to around 8.5 - 9.2."
