thanks Jim and sorry about the link. definitely i get a bigger case. you're right!
the only thought, think need midi, some devices that sport a USB port as well. so i can connect my computer directly to my Eurorack system. like µMIDI Intellijel. also a weird sequencer maybe Pam's and mimetic.
I would like to hear your thought if it's not trouble

you might want to look at the expert sleepers fh2 - or just look at modules on here: midi (function), usb (search field)

you'll have to sift through quite a few - make sure you get midi to cv modules and not cv to midi!

Utility modules are the dull polish that makes the shiny modules actually shine!!!
