Repeating Midi cue

Post by Boswell » Sat Jul 04, 2009 8:22 pm

Can anyone think of a way to have a simple Midi send cue auto repeat ( say every sec) and not affect the normal operation of the cue list? (aka hot key type)

I'm trying to find a way of having a simple watchdog that sends out a midi message every second to refresh an external timer, If SCS stops for any reason, the timer drops out and it will swap over onto the slave computer (which is kept in sync).

Don't want Mike to write new code for this, it's just me trying to make our systems more secure.
regards

Could you send a MIDI system exclusive message, either as a cue or a sub-cue to Q1, that would continue in the background while the other cues are running. It may gobble up system resources - but surely not too much as MIDI. I don't know about SCS, but Sonar takes about one minute to send an 8KB sysex file. This wouldn't achieve your "pulsing", but hopefully the clock would detect a voltage from the MIDI stream.

It may also have to be on a different MIDI channel from your other MIDI cues. Perhaps it could go to a ficticious device ID???

I have used multiple repeats of F0 F7 F0 F7, etc., as a sysex to achieve delays in a midi message where the device wasn't able to process the data quickly enough.

Just a thought...!
