Loop Scrolling Script

[glynndub]

Strange but the script below doesn’t always work correctly, Sometimes some track loops have to wait an additional loop cycle before moving down to next loop (which tracks can vary) therefore some tracks will be on loop B and some tracks on loop C etc, but by the end of the scrip all tracks are back on loop A.

Stranger still is if I stop and restart song using “global pause” then script rectifies itself and behaves correctly moving all loops down and back to loop A simultaneously.

Anyone got any ideas why this would be so? Thanks

# All tracks move to loop A
wait loop

loop 1
next

# All tracks move to loop B
	wait loop
	for *
	NextLoop
	next

# All tracks move to loop C
		wait loop
		for *
		NextLoop
		next

# All tracks return to loop A
			wait loop
			for *
			NextLoop
			next

end

Are all loops the same length, same no. of loops per track? (three?). Any quantize issues perhaps?

Could it be that when loop B is called (eg), the first track moves to loop B, then as the next track does, loop B has already started, so the wait statement waits the additional loop before being called?

There also seems to be a duplicate loop A call as in the first statement, 'loop 1', and the last 'returns to loop A' statement, 'nextLoop' (assuming you have only three loops per track).

Wild guesses here really!

Right, for this to work the loops in all tracks must be exactly the same size. You would need to have used either Empty Track Action to copy them, or Track Sync. MIDI sync and Host sync do not always create loops exactly the same size, they will be close but even if they are one or two samples apart this script would not work (this is being fixed in the next release).

Thanks Jeff… I do recall reading this somewhere in the manual now!

Thanks for your input Dave.

Sure, I knew that was the problem I just couldn’t see why it was happening.

The idea behind writing it this way is so regardless of which loop all tracks are on.
(A, B, C,)
AKA
Eg (Verse, Chorus, Bridge,)
The scrolling script always starts with "A" first, progress on and finishes back on "A"

Thanks again Dave

Also sorry to one and all this should have been place in the scripting section… D’oh
