Usage:
midimap [--help] [-d] [-f] [-a @alias value]+ [-m "Input Device" <mapfile>]+
With no arguments specified, midimap will simply list the available sources
for MIDI input.
-d Debug mode (verbose logging)
-f Force low CC for all CC values; this is useful for devices that don't use
high CC at all, and treats all CC messages as low resolution
-a @alias value
Create an alias; aliases can be used for giving meaningful names to
numbers, controllers, or RPN parameters
-m "Input Device" <mapfile>
Listen for messages from "Input Device", and apply the rules outlined
in the <mapfile> for every message received
-h Help
-v Print version and exit
The program will output the results to a single virtual MIDI device, named
in the format of "midimap", "midimap 2", "midimap 3", etc, for each
copy of the program running.
Input Devices:
The program will always list out the available input devices. For example:
Source 1: "Keyboard A"
Source 2: "Keyboard B"
Source 3: No Name Available
Source 4: "Pads"
Source 5: "Pads"
Sources can be specified using the name:
midimap -m "Keyboard A" <mapfile>
Or the source index:
midimap -m 5 <mapfile>
Map Files:
Map files consist of a list of event handlers and aliases. If the handler's
criteria matches the message, the instructions in the handler are executed,
and no further handlers are executed.
Alias @TargetChannel 16
OnNote 1 NoteGb3 Any
# Change the Gb3 to a C4
Print "Received:" Channel Note Value
SendNote @TargetChannel NoteC4 Value
End
For this example, if the input device sends a Gb3 message at any velocity in
channel 1, the program will print the message, and send a C4 instead on
channel 16.
The OnNote line is what message to intercept, and the matching criteria
for the message. Criteria can be a literal value, `Any` which matches
anything, or `Positive` for a number greater than zero. Inside the handler,
the instructions are executed in order using raw values ("Received:", 16,
NoteC4) or values dependant on the original message (Channel, Note, Value).
Any line that begins with a `#` is ignored and considered a comment.
All event handlers end with `End`.
Event Handlers:
OnNote <Channel> <Note> <Value> Note is hit or released
OnBend <Channel> <Value> Pitch bend for entire channel
OnNotePressure <Channel> <Note> <Value> Aftertouch applied to note
OnChanPressure <Channel> <Value> Aftertouch for entire channel
OnPatch <Channel> <Value> Program change patch
OnLowCC <Channel> <Control> <Value> Low-res control change
OnHighCC <Channel> <Control> <Value> High-res control change
OnRPN <Channel> <RPN> <Value> Registered device parameter
OnNRPN <Channel> <NRPN> <Value> Custom device parameter
OnAllSoundOff <Channel> All Sound Off message
OnAllNotesOff <Channel> All Notes Off message
OnReset <Channel> Reset All Controllers message
OnElse Messages not matched
Parameters:
Channel MIDI Channel (1-16)
Value Data value associated with event (see details below)
Note Note value (see details below)
Control Control being modified (see table below)
RPN Registered parameter being modified (see table below)
NRPN Non-registered parameter being modified (0-16383)
"Value" is a number that depends on the event:
OnNote Velocity the note was hit (0-127) Use 0 for note off
OnBend Amount to bend (0-16383, center at 8192)
OnNotePressure Aftertouch intensity (0-127)
OnChanPressure Aftertouch intensity (0-127)
OnPatch Patch being selected (0-127)
OnLowCC Value for the control (0-127)
OnHighCC Value for the control (0-16383)
OnRPN/OnNRPN Value for the parameter (0-16383)
Notes:
Notes are represented in the format of:
`Note<Key><Octave>`
Where Key can be one of the 12 keys, using flats:
Key = C, Db, D, Eb, E, F, Gb, G, Ab, A, Bb, B
And Octave can be one of the 11 octaves, starting at -2 (represented as N2):
Octave = N2, N1, 0, 1, 2, 3, 4, 5, 6, 7, 8
The last addressable MIDI note is NoteG8, so NoteAb8, NoteA8, NoteBb8 and
NoteB8 do not exist.
Therefore, the entire range is: NoteCN2, NoteDbN2, ... NoteF8, NoteG8.

If -f mode is used, then high-resolution controllers are interpreted as
two separate low-resolution controllers. These are identified by taking
the high-resolution controller name and adding MSB or LSB to the end.
For example:
ControlBank (00/20) becomes: ControlBankMSB (00) ControlBankLSB (20)
ControlMod (01/21) becomes: ControlModMSB (01) ControlModLSB (21)
...etc
The -f mode also disables RPN/NRPN conrols, and instead interprets the
CC messages as low-resolution controllers with the names:
ControlDataMSB (06) ControlDataLSB (26)
ControlPNIncrement (60) ControlPNDecrement (61)
ControlNRPNSelectLSB (62) ControlNRPNSelectMSB (63)
ControlRPNSelectLSB (64) ControlRPNSelectMSB (65)
Registered Parameters (MIDI hex values in parenthesis for reference):
RPNBendRange (00/00) RPNAzimuth (3D/00)
RPNFineTuning (00/01) RPNElevation (3D/01)
RPNCoarseTuning (00/02) RPNGain (3D/02)
RPNTuningProgram (00/03) RPNDistanceRatio (3D/03)

RPNPanSpread (3D/07)

Aliases:
Any number, Note*, Control*, or RPN* keyword can be aliased to another
keyword starting with @. For example, if your MIDI controller sends
ControlReserved1 when hitting the play button, you can alias it via:
Alias @PlayChannel 1
Alias @PlayButton ControlReserved1
Then, it can be referenced anywhere else, like:
OnLowCC @PlayChannel @PlayButton Positive
# play was hit...
End
Aliases can also be defined from the command-line using -a:
midimap -a @PlayChannel 1 -a @PlayButton ControlReserved1 ...etc...
Commands:
Print "Message" "Another" ... Print values to console
(`Print RawData` will print the raw bytes received in hexadecimal)

SendNote <Channel> <Note> <Value> Send a note message, etc
(Use 0 for Value to send note off)
