[RWP] Time Selection and Trimming Midi Loops

[indigo]

Colin, I haven't done it yet, but it seems to me if you can nudge or 
scrub to the very first note of your audio, and set beginning of loop 
with alt+left bracket, then move to the  very last sound on your audio 
item, and set the end of loop with alt+right bracket; and when you play 
the loop you hear nthat notes aren't being chopped off at either end; 
then   you're in a good position to split items with shift+S and end up 
with 3 items, item 1before your music begins;item 2 your music, and item 
3after the end of your selection.
You delete item 1 and item 3, and you have the audio loop.
Colin, you know, at this point; if I really wanted the audio to loop 
seamlessly, I'd take it to Sound Forge, where I have experience with 
adding or subtracting samples to a loop, until I get a perfect zero 
crossing, no click or gap.
But, please tell me if this is right; first, to get the audio aligned 
with beats, in Reaper; there's a setting in general project settings to 
choose measures beats length.
I'd select that.
Then, right near that selection there's another that seems to be for 
forcing to align with beats, not the exact words, but I believe that is 
what it's for.
That selection was also close to one about Reaper's default stretch 
plug, Elastique.
Then I'd turn on the metronome and learn if the audio's loud transcient 
points, like the kick drum, are being forced to align with beats.
Actually, it might be better first to manually align as close as 
possible with the tap tempo button, if that works in ReaAccess, then 
force the transcients to align with beats afterward.
When I get back in Reaper, I'll get the correct wording for those 
project selections and test this out; but am I right about what they do?
Then, after the audio aligns with beats, I'd save it and  take it to 
Sound Forge to make it loop seamlessly.
I'm loving this thing!
