[sdiy] Is MIDI Active Sense necessary?

[Jacob Watters]

I never knew that this existed, but I would like to implement it. Do
you have an example of how that is usually done?

I have been getting an occasional note stuck on when routing the
controller through Ableton Live and then to a synth controlled by an
ATMEGA328 (Arduino). I think there is a bit of lag in Ableton that
causes the note messages to get bunched up and then it floods the tiny
buffer on the chip. It rarely happens, and only when holding down one
note and playing many other notes very quickly, but I would like to
resolve the issue if possible.

Thanks!
