MagicQ User Manual 277 Version 1.4.9.0
33.1.2 MIDI receive
To receive MIDI commands, first set the MIDI In Type in the Setup Window. You can choose between
“None”, “Any chan” and “Requested Chan”. When set to “Requested Chan” the requested channel is
configured in the MIDI IN Chan field.
When using the MagicQ MIDI/SMPTE interface for MIDI only the Timecode options can be set to none
and then the last received MIDI command will be shown in the Status Display.
MagicQ uses a text mapping file, miditable.txt in the MagicQ folder to convert from MIDI commands to
MagicQ serial commands.
An example file miditable.txt is included which maps midi notes to the playbacks PB1 to PB34. Each line
in the file specifies a received MIDI command and then the mapping to the serial command in inverted
comments “”.
For example, the first to lines in the default file are:
144,36"1t"
128,36"1u"
MagicQ checks the received MIDI note byes to see whether they match the values. So if the MIDI
message matches 144 36 then it executes the remote command 1t (Test Playback 1). Similarly if it
matches 128 36 then executes the remote command 1u (UnTest Playback 1).
Note that Test and Untest are like Activate and Release except they force the Playback level to be 100%
and 0% respectively.
Note that for security reasons MagicQ limits the number of playbacks that can be controlled using MIDI
and the remote protocols. On MagicQ consoles PB1 to PB34 can be controlled. On MagicQ PC,
playbacks PB1 to PB10 can be controlled.
Users may use their own MIDI conversion file “usermidimap.txt” rather than the in-built “miditable.txt”.
This avoids user midi tables being overwritten when new software versions are loaded, since only the
“miditable.txt” is updated on software updates.
33.1.3 Advanced MIDI mapping
It is possible to match all 3 MIDI message bytes including the velocity. So for example:
144,36,100”1t”
144,36,101”1u”
This would execute the Test Playback 1 when Note On for note 36 at velocity 100 was received and
Untest Playback 1 when Note On for note 36 at velocity 101 was received.
To jump within a Cue Stack instead of testing / untesting a Playback just change the remote command in
the inverted comments.
144,36”1,10j” // Jump to Cue Id 10 on Playback 1
