Hey all!
I am just planning my first AE Modular Board and am really excited about it. I was always interested in going in to the modular synthesis world but the eurorack hype and pricings always discouraged me. Anyway I am happy that I found AE!
I own a MS20 mini and would like to know if I can send controlls from the AE to the mini and the other way around? I guess with the 4I/O modul it would be no problem? Is there also a way to implement in a AE Modular the function the MS20 has to create envelopes and CV from an external audio signal? And as a general question about modular, is there a difference between CV and the signal coming out of LFO or ENV? Or is that all called CV?
Thanks already!

Hi krischo, yes you can send and receive signals between the MS20 and the AE Modular using either the 4I/O or the jacks in the Master module. An envelope follower for the AE Modular doesn't yet exist but is in the early stages of development! CV just means Control Voltage as opposed to Audio signal, but in the end you can use either to modulate things. It's fun to just stick an audio signal where you expect an envelope or LFO! |

Doesn't GRAINS have a community firmware for an envelop follower?

Some notes about the MS-20 (OG, mini, and FS, actually)...first up, the CV scaling for the MS-20 is NOT volts-per-octave. Instead, it uses a linear (also known as Hz/V) scaling...which is quite odd these days, but it's how the original worked as that was somewhat more common back in the late 1970s. Also, the gate/trigger signals are INVERTED, like the Moog S-trig. Although, unlike the S-trig, it doesn't have that voltage sag issue that would cause random mistriggering. In the Eurorack world, there are modules that are specifically designed as gateways to/from the MS-20 (and similar synths) which deal with the rescaling and inverse g/t issue.

Thank you all for your messages! I guess I will just try what happens when I connect the MS20. As nothing can be damaged (hopefully) sounds like it could sound interesting  And yes I already have an eye on the Grains. |

Hey Krischo,
I have been using AE and ms20 for about a year and can tell you that they work quite well together.
Some things you need to consider:
- You will probably need a 4 I/O Module dedicated solely to the communication of these 2 systems. I have my AE just above my ms20, and the ms20 patch cables are long enough to do the job.
- as someone mentioned before, ms20 trigger in expects an inverted trigger. Also if you want to use the lfo of ms20 and send it to AE, you might want to invert that too. So make sure you order some AE modules that can invert. The logic board can invert only triggers. The 2 att/cv can invert triggers and envelopes.
- as for pitch control of the ms20 via AE, the Vco 1+2 cv in of the ms20 is good, but the ms20 keyboard is disabled once you connect something to it.
The trick I ve been using lately is: I send cv to the Freq input of the ms20. That way I can still use the ms20 keyboard, and transpose a sequence sent from AE for example. BUT, that way the lowest pitch sent from AE to the ms20 doesn't exceed the lowest note of the ms20 keyboard. That's not the case via the vco 1+2 cv input, from which the AE can make ms20 play amazingly low notes. So what I do is use one of these dual mono to stereo adapters on the Freq input, connecting both AE and the mod wheel output of the ms20, with the mod wheel turnt all the way down. That way I can reach those super low pitches again.
That's all, hope you manage to decypher what I wrote 😅

Ah forgot to mention, if I'm not mistaken (haven't used that for some time), the Freq input of the ms20, when you turn the relevant knob that controls the amount to max, works in 1.2 V/O.

Cool! Thanks for that info! Do you have any video or sound example of your fusion with the AE and the MS20?
