Need some suggestions

This will be my new 9 U Rack, its actual emty
ModularGrid Rack
Its primary a Synth, some Lines below are the 6 U Rack that wants to be a Drummachine, need here some suggestions too.
ModularGrid Rack
A idea about the Sequencer:
ModularGrid Rack
(nice or too much?)

9U is controlled by the PC over Midi, later the 9U will control the Sequencer by the clocking from it.
Musicstyles are mixed electronic from Experimental, Drum n Bass, IDM, BigBeat, Dubstep to Dub.

Thanks Feedback.
