Been trying to figure this out for a while with no luck.
Its an attempt at making an abstraction which is similar count~, tap.count~ etc... but unlike those, is turned on/off at signal rate and also has it's length/count modulo set at signal rate.
The patch is commented if anyone feels like having a go!
I'm out of ideas.
(it's a little annoying that count~ and co are not fully signal controllable already, as they seem to be made for use when accuracy is important)
