Hologram Microcosm

Microcosm's effect engine, its modulation and reverb, and the whole looper.

Page one is what you would reach for on the pedal: activity, shape, time, repeats, space, filter, resonance and mix. Page two is the modulation, the reverb and the loop levels.

Page three is the looper's modes, and it is the reason this file exists. Playback division, direction, routing, looper-only, burst, quantise and the hold sampler are all footswitch holds and combinations on the pedal. Here each one is a labelled detented knob that shows you the state without you having to remember it.

All eight switches are used, and six of them are the momentary looper commands: record, play, overdub, stop, undo and reverse.

Every CC and every value split comes from Hologram's own implementation chart.
