I've been working on some projects where visuals are slaved to Ableton. The problem is, when using Ableton's envelopes to automate layer fade in/out (and this is a MIDI limitation) on long fades, the fades aren't smooth. You can see it cycle through the 128 steps of intensity-
SO my work around has been to slave the layer opacity faders to a TCM, and use a MIDI note to trigger fade in/fade out. This has been pretty good- but being the tech geek that I am I know it can be better-
So I'd like to have a series of 4 buttons- probably a control surface- that could be pressed to change the fade time between a BAR, a half bar, a quarter bar or eighth bar- as determined by BPM. I've figured out the math part- BUT I can't remember the correct text to enter to pick up the BPM value in the "do math" field. The sad thing is I did this yesterday and it sort of worked.
I'm also using the plug in that destroythings created:

to pick off the BPM data...
