I use the Analog Keys (and before it, the Analog Four) with my modular quite a lot. I have a room full of modular and vintage synths of all sorts, with lots of different voltage/gate/trigger requirements and I have never encountered a better companion for these instruments. I so loved using the A4 with my vintage gear that I swapped it out for the AK in order to make it my “master CV keyboard”. All four of the AK’s CV outputs are routed to a patchbay so that I can easily send any of them to any synth in the room. I actually wish I’d kept the A4 so that I could have double the CV on hand, but lacked the space. Maybe I’ll eventually make room for a MkII.
The coolest thing about the A4/AK is how flexible the CV stuff is. I’ve used it with my modular, Minimoog, 2600, VCS3, original MS-20 and Odyssey. Most of these have different requirements (s-trig vs v-trig, Hz/V vs V/Oct, 10v gates vs 4v triggers, .032v/Oct vs 1v/Oct, etc). The A4/AK never let me down.
For the past few days I’ve had a big ‘Berlin School’ thing set up in which the AK is sending 8th-note gates to the modular to act as a master clock. It’s also sending a master pitch voltage for each gate. I’ve got three different sequencers clocked to it and each set up to play a different sequence in C-minor. I’ve got the remaining two AK CV outputs sequencing an ARP 2600 - also in C-minor. The four other tracks on the AK are also sequenced. All of this is on a single pattern. By programming all sequences in C-Minor, I can then use the AK’s Transpose function to transpose all of the various sequencers in realtime. It’s really, really, cool.
