+
+Maps midi signals coming from ALSA midi devices to shell commands
+For a release build: `$ make clean ; make -B RELEASE=true`
+
+usage: midiMap <config file>
+This is a daemon program, it does not start any background process by itself and needs to be constantly running for the mapping to be active
+
+This program is in early stage but is fully functional without any major errors
+
+TODO:
+- Use integrated C MIDI control
+- Support for multiple identical devices
+- Support for system reserved commands
+- Options
+- Better error handling on wrong config file format
+
+
+See 'example.mim' for an example config file
+
+
+-- COMMAND FORMAT --
+
+Format is a regular shell format
+
+-- Environment
+- Global
+$channel: channel of the
+$id: id of the note/controller
+
+- Note
+$velocity: velocity of the note
+
+- Controller
+$value: value of the controller (remapped)
+$rawvalue: original value of the controller
+
+
+-- FILE FORMAT --
+[<device>,<device>]
+
+- <device> format:
+{
+name=<name>
+commands=[<command>,<command>]
+}
+-
+*name: string referring to client name of the device ($ aseqdump -l)
+
+- command format (global):
+{
+type=<note/controller>
+id=<x>
+shell=<shell command>
+channel=<*/x>
+}
+-
+*id: value from 0 to 127 referring to id of note/controller
+  > mandatory
+*shell: shell command to be executed
+  > mandatory
+*channel: value from 0 to 16 for channel. Can use * for any channel
+  > optional, default *
+
+
+- <command> format (note)
+{
+trigger=<x:y/x>
+}
+-
+*trigger: note velocity from 0 to 127 that triggers the command. Can enter an interval x:y or single value
+  > optional, default 1:127
+
+- <command> format (note)
+{
+range=<x:y>
+remap=<x:y>
+float=<true/false>
+}
+-
+*range: controller value from 0 to 127 that triggers command. Can enter an interval x:y or single value
+  > optional, default 0:127
+*remap: remaps the range to given interval. Interval can be inversed and float
+  > optional, default same as range
+*float: boolean value defining if output is a floating point value
+  > optional, default false
+
+- Comments can be written inside {} by doing //=<COMMENT>
