MagicQ User Manual 252 / 355
MIDI note commands are 3 bytes long, consisting of the command (note on / note off) byte, followed by the note and then the
velocity
<note on/off> <note> <velocity>
For example, to send a note for middle C set the macro field to the following:
N144,60,127 // Note 60 on velocity 127
N128,60,0 // Note 60 off
MagicQ accepts both ‘N’ and ‘n’ to specify MIDI commands.
35.3 MIDI problems
The MagicQ MIDI/Timecode interface can be easily tested using the test show midilooptest.show. This show simply runs a 2
step chase on Playback 1 which sends out MIDI commands corresponding to activation and release of Playback 2.
• Connect the MIDI interface to MagicQ
• Connect a MIDI cable from the Out to the In on the Interface
• Set MIDI In Type to “Any chan”
• Set MIDI Out Type to “Any chan”
• Load the midilooptest.shw
• Raise Playback 1
• If MIDI is working then Playback 2 should activate and release every 1 second.
If the loopback test works but connection to external equipment is failing, then try to insert active splitters or IN/THRU links into
the system.
Note that we have experienced some problems with the signal level transmitted from low cost PC MIDI dongles operating at
3.3V. From July 08 our interfaces have been improved to boost the signal received from these devices.
35.4 MIDI Show Control
MagicQ supports MIDI show control when connected to a ChamSys 2010 MIDI/Timecode Interface.
MagicQ responds to the GO, STOP, RESUME and TIMED GO commands.
The effect of the MIDI show control commands is determined by the MIDI show control type. This is configured in Setup
Window, View Settings, MIDI/Timecode, Show Control Type. The options are Normal, Cue Stack 1 and Playback 1. This
is useful for integration with (e.g.) Strand consoles which only have 1 Cue Stack and which do not allow the show Control
commands to be configured.
When set to Normal then MIDI show control commands trigger Cues in the Cue Store or Cue Stacks in the Cue Stack Store.
MSC commands with two parameters (Q number, Q list) will trigger Cue Stacks in the Cue Stack Store. MSC commands with
one parameter (Q number) will trigger Cues in the Cue Store.
When set to Cue Stack 1 or Playback 1 then the commands will affect Cue Stack 1 or the Cue Stack stored on Playback 1
respectively.
MagicQ ignores the times in the TIMED GO command and uses the programmed times. GO and RESUME have the same effect.
MagicQ MIDI/Timecode interfaces manufactured prior to October 2009 must be upgraded to latest firmware by ChamSys to
support MIDI show control messages. Please contact your dealer/distributor for more info.
