Generating too many MIDI controls

[Paul DeRocco]

I'm using the current Cakewalk. When I draw in the controller pane of the piano roll view, it seems to generate every single 7-bit value for the control, sometimes even generating duplicates, even if that translates into thousands of messages per second. This is insane. How do I limit the rate to something reasonable, like 200Hz? The few provided thin*.cal utilities are too stupid, since they're not based on time. Is there a setting for this somewhere?

You've two options:

1. Change the grid snap value on the PRV to a longer note duration,  so that less controllers are generated; or

2. Use  automation in the MIDI track instead.

The PRV snap value doesn't seem to have any effect, and would be too coarse anyway.

It appears that Cakewalk limits the control rate to the tick rate, so a very steep change skips a lot of values but generates output on every tick. So at 120bpm I could attain a 192Hz limit if I reduce the ticks per quarter note to 96, but I think that's too coarse. I think I want the timing of percussive events to be more accurate than the spacing between controls. I'm now trying to solve it with a thinning .cal file of my own.

Controller interval should follow either global or PRV snap, and you can set a value in ticks if 128th triplet (20 ticks = 10ms at 125bpm) is too coarse (?).

It doesn't pay attention to PRV snap, only global. 10ms is okay for the controls, but not for note timing, so I just have to remember to turn it on only while I'm drawing the controls. Thanks for the pointer.

If you already have entered controller events that are too bunched up, you can use the CAL script "Thin Controller Data.cal".  I use this all the time.

Hope this script is in your CAL scripts folder as defined in Preferences | File | Folder locations > Cal files

It does for me. If PRV snap is at a higher reslution than Global snap, I get controllers drawn at that smaller interval.
