33.1.5 Remote commands
For the latest list of remote commands check the section on ChamSys Remote Protocol Commands.
33.1.6 MIDI problems
The ChamSys MIDI 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 Playback2.
• 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.
33.1.7 MIDI Show Control
MagicQ supports MIDI show control when connected to a ChamSys 2010 MIDI SMPTE 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.
ChamSys MIDI/SMPTE 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.
