Thanks for the feedback I will look into the A-185. I have had the two Moogs for a while and pretty familiar with the subharmonicon. I really like it and have used it as the basis for a couple tracks, using one sequence for a bass line and seq 2 to form a pluck sequence over the top. From watching some videos it seems the Spectravox and Labyrinth are even more experimental so not for me. I thought about a second M-32 but decided to go for more variety.
Yeh the reason I ask about the ribbon cable is to consider how I am going to connect them all together, as the Moogs are in cases. I will take them out and mount into the rack so I can take advantage of the power supplied by ribbon cable. Looks like it's going to be cable spaghetti for the audio tho.
