As soon as I get my Maschine Studio, it'll look like this;
Maschine Studio as control hub with one MIDI out to MIDI-patchbay, which then goes into the MonoMachine, Analog 4 and the Octatrack.
Two direct MIDI outs from Maschine Studio to Machinedrum and Blofeld Keyboard respectively.
MIDI out from MPD32 either directly into Maschine Studio or via MIDI-patchbay to control volume of tracks in Maschine Studio and other effect parameters. Also using the pads for tracks on/off.
Blofeld Keyboard via MIDI-patchbay as master keyboard (if needed).
Everything goes into the Soundcraft-mixer, into the RME Babyface, and possibly back into Maschine Studio.
Ideally I'd like to route all audio inputs back into Maschine Studio for mixing, but not sure if it's going to be possible or if I can afford the necessary gear for it.
Really stoked about this though, it'll be sweet!
