+# Minimal Mackie emulation for the Harley Benton MP-100 a.k.a. MeloAudio MIDI
+# Commander foot controller (https://meloaudio.com)
+
+# This device is rather limited in what it can do as a Mackie controller (no
+# feedback, just 4 switches, 4 toggles, and 2 continuous controllers), but it
+# may still come in handy to guitarists for basic hands-free DAW control. Note
+# that we can't make good use of the bank switches on the device (the two
+# extra switches on the right), since these always emit a PC message, which
+# interferes with our use of the PC messages for the transport controls. It
+# may be possible to do something better by configuring a custom mode on the
+# device, but here we stick to what's available in the factory settings.

+# The following configuration assumes that the MP-100 is set to mode 1 (JAMP),
+# which is the default. Note that the controller numbers for the top row and
+# the expression pedal inputs are specific to JAMP mode, so you will have to
+# adjust these if you run the device in a different host mode. As implemented
+# below, the controls are laid out as follows:
+
+# top row:    [mute] [solo] [rec]   [select]  EXP1: volume (current channel)
+# bottom row: [stop] [play] [chan<] [chan>]   EXP2: volume (master)
+

+
+# Note that MCP expects a note-on/off pair for each activation of the
+# mure/solo/rec/select switches, while the MP-100 top switches act as toggles,
+# so we have to use suitable mod translations for the top row.
