# MidiMix Mapping
This is how I assign the knobs on my Midi Mix to the Rack 2X (mainly thinking about controlling the Usual Suspects emulation). I'll probably do a similar assignment for the Mopho where possible (esp filter cutoff and env settings), though in the case of the Mopho I may want multiple mappings to choose between.

# Thoughts
At some point I may add the table for the patch dump format.
Also if I find need, I may write some simple Python scripts to manage the Rack2X,
and to e.g. copy/paste/modify parts of a patch between patches (e.g. take amp env
from patch 1, apply it to patch 2, and write the output to patch 3).
