Hello, I'm using multiple Max4Live Midi LFO's to send midi continuous control data to my DMX software - D-Pro (Enttec) - specifically to control X&Y coordinates of moving heads. I've also set up dummy clips to send various CC messages to control other aspects of my lighting rig. Color, Gobos, Prism, Rotation, Dimmer, etc...

It all is working exactly as I would expect UNTIL I try and record all the data from these multiple midi tracks full of CC messages to one midi channel to create a single dummy clip with all of the currently running clips to create a snapshot of the current parameters to be recalled, like a "scene". When I do so the problem is there seems to be a minor delay from the start of the clip and the start of the CC messages that are being recorded. All the CC messages are there but the data starts at 0 on all for a fraction of a beat before the CC message begins being recorded. This of course causes a hiccup as the lighting rig receiving all 0's before the correct commands every time the clip repeats. Any clue why this delay in recording the CC data occurs? If I move the start position of the clip past this point it seems to resolve this issue partially. See my next paragraph for what I believe to be the next issue with recording scenes(dummy clips) as I am attempting to do.

Let's say I have a dummy clip set to send CC value 127, for the CC message to be sent and affect my light I seem to have to make sure there is a change in the data say from CC value 126 to 127 or nothing happens. Why is this? Is there anything that can be done to make it resend the 127 value even if I don't edit in the slight change from 126 to 127. On the many channels of CC messages that are required to control lighting this is a very tedious process to do so.

Thanks in advance,
Jason

I need to investigate but I believe that live filters duplicate ccs. There are some good infos about it in the manual of the NRPN M4L device you can download on maxforkive.com
Hope this helps

Thank you that is helpful! According to the manual you directed me too, and my experience, I would have to agree with you that live is indeed filtering duplicate CC's. I actually may have found a work around. I'm still in the trial stages and as I get further along I will post in more detail exactly what I am doing.

For now though I have discovered that if I use the Max4Live Midi LFO and turn the depth to zero so that no oscillation is occurring I can adjust the offset knob and get the full range of CC's to send repeatedly. I've verified this is occuring with midi monitor. Bonus is at any point I want to oscillate the CC data I can do so by simply turning the depth up and adjust rate and phase to my desired position.

As for the first issue of delayed recording of CC data when recording from midi clip to midi clip I'm still unsure what is causing this. I've decided to forego doing it this way. I will just manually copy the various clips that make up a "scene" into a row of clips to be launched simultaneously in session view.
