This is my outside world interface rack. It lives with (3) other 10U racks full of MOTM format modules I've built (except for the Encore Frequency Shifter). Check em out!
The ES-3 takes 8 channels of lightpipe from my Logic DAW & can send/receive audio (modular & line level), drive & calibrate VCOs, sync analog clocks & LFOs with Logic sessions & drive modules with software based step sequencers & LFOs.
The Mobius interfaces via MIDI & can sync with my Logic rig as well.
This rack is also my 1st leap into Eurorack land. I'm liking the lights!
