Some general MS-20 interfacing questions

Post by otto » Mon Feb 08, 2010 11:40 pm

So it’s HZ/V. What does it work well with and what does it not work well with? The MS-50 and SQ-10 are obvious but expensive. I’ve heard people recommend the Moog CP-251 but being V/Oct, is it that usefull?

Does the MS-10 add much as an expander or not?

What are the options for midi conversion?

I had both MS-10 and 20 hooked together for a great experience. Kinda like an MS-30 :lol:

But yeah, you'll need a Kenton Midi-Cv converter that has both Cv and hz/v.

Or the MS-02 converter box.

Yep. I got the 10 before the 20 and using the 10 as a third oscillator, like a 32' triangle, causes some serious rumble in the jungle. Sure it doesn't have all the patch points/options the 50 has but it didn't cost me no 2K or whatever they sell for. It does have PWM that that 20 doesn't have. If you can get a nice one at a cool price sure and re-sell it for whatever you paid if you don't require it.

The Kenton midi-cv works great. I can patch the aux 1 to whatever and use cc's to alter the parameter or do sweeps in time with whatever music is being worked on. It also has an LFO that can be applied to the CV or the AUX. The only thing I just realized yesterday is that cv/gate isn't like midi and you can't just connect the kenton -> 20 and 20 ->10(cv/gate n00b). Luckily the forum member I bought my 20 from a while back included the 02 so I can split each out of the kenton like 2 or 3 times with the junction/multiples.

I haven't gotten a CP-251 but when I see people use them they use them straight up. I am not an analog pro or anything but the MS-20 inputs use anywhere between -5v and +5v. The hz/v thing applies to pitch/notes don't it? I got the Kenton first because I wanted to integrate it into the midi environment, it has an LFO and I can do without what the 251 does for now.

yeah hz/v is only the pitch, all the vcf ins and the second in for the vco are exponential like v/oct and use -+5V. the hz/v in wants to see up to 8V. theoretically, it is also possible to control the whole range of the oscillator with the second (+-5V) vco in, but it's relative to the keyboard. it is for example possible to use motu volta with that input, but not with the hz/v (cause the interfaces don't give out that much V). volta calibrates it, so it's easy, i dont have experience with kenton...

the MS10 is great in addition to an MS20. you don't only get an extra vco. there is another lfo, env, noise, mod wheel... it is great fun for FM. and, it's external audio input is a crazy distortion. you would need a cv merger / splitter to really benefit from it though...

MS-10 & 20 both work AOK w/ FR mobius sequencers. both for control via those & for midi/cv conversion from anything else.

Oh yeah, I thought I'd read that about mobius somewhere. Can you also scale the voltage with the mobius? My EML takes 1.2 v/oct...

weird, i don't think so... just 5 & 12...

i got a cp-251 with my ms20 and it's a lot of fun. i don't have a modular so the mutiples, mixer, 2 attenuator and a lfo that can receive modulation (i plug the lfo from the ms20 to an attenuator then to the pedal in of the lfo on the cp-251).

the ms10 would be fun to, for the pwm.

you can do that with every (active) expression pedal or the MS mod wheel, or anything else. through the patchbay vca

i'm still learning how to extensively and effectively program it but how could you modulate the lfo like that? maybe i don't have the correct term with "modulate the lfo" ?

well, you want to introduce the lfo modulation by pressing the pedal, right?

the patchbay vca on the MS is just an attenuator. plug the MS lfo to its input, it's output to your lfo mod destination (i guess pitch for vibrato most of the time), and the source you want to control the effect in the control input (mod wheel, expression pedal, another lfo if you have one, etc...). the standard routing to the control is EG1 (delay, attack; nice too for vibrato). the input signal gets attenuated by the control input, and is then passed on to the output. also nice if you want to attenuate other cvs that go to synths without pots for cv in amounts.

that's not what i'm trying to do. i do change the shape/speed of the lfo by using the output of it from the ms20 to the cp-251 input express pedal. with both speeds being different it can be very interesting because the high and low never cross at the same place in their cycle. in short i don't introduce the lfo, i affect it. it sound a bit like a sampling and hold but not linear in time.

you made me realise that i could also use the mod wheel out from the ms20 and mix it with the lfo, this increase how the lfo from the cp-251 is affected.

BTW, i'm using it for lpf
the patchbay vca on the MS is just an attenuator. plug the MS lfo to its input, it's output to your lfo mod destination (i guess pitch for vibrato most of the time), and the source you want to control the effect in the control input (mod wheel, expression pedal, another lfo if you have one, etc...). the standard routing to the control is EG1 (delay, attack; nice too for vibrato). the input signal gets attenuated by the control input, and is then passed on to the output. also nice if you want to attenuate other cvs that go to synths without pots for cv in amounts.
thanks for this vca/EG1 tip.

no problem ;)

in this case, you need the cp251... unfortunately the ms20 has no cv input for lfo speed or shape...
