hey jim, thanks for your comment.

i was thinking a lot if i should keep the moogs in there cases, cause than i could just build a small rack which saves money at the end. but on the other hand if everything is placed in one bigger case it would be easier to patch i guess. i thought i have enough utility modules.

sound source: would be the moog oscillators than
sound modifieres: what would be apart from a filter?
modulation sources: whats missing, i have lfo, envelope follower and generartor
utility - what is missing? i have vca, attenuators, slew, offset
what would be an example on how to use a matrix mixer. i don't understand what would be the benefit of using one.

thanks
