one thing that is cool about recording midi in FLStudio, is when you go to record an 8 bar loop, it wont really start adding notes until you start playing -- and then if it goes to 9 bars, but there is no midi notes in that 9th bar, it will trim that last bar off, and you have a nicely made midi loop.
get the idea?
I think it would be great in REAPER.
instead of having a lot of space in front of and after your actual midi recording, it trims automagically to only the stuff you played. Its not destructive in any way because this includes any CC messages, ANY midi stuff.
I cant think of any reason this shouldnt be in there
