Back to what looza said, the concept that 16th beats are represented in the ‘sync’ box are assuming you use speed of 6. You need to double that number if you halve your speed…for instance, the same 4 bar loop at song speed 3 need 32 put in the box.
Generally, if you’re working in 4/4, it’s encouraged you use 3 as your base for speeds (3,6,12,24,48,etc). This will make your syncing of loops and other such 4/4 items feel more natural when doing the math because it will correspond musically with 16th notes, 32nd notes, 8th notes, etc.
Back to 09xx command, something you can try is to manually quantize a drum loop. It’s a bit of work, but the results are well worth it.
First, open up your raw drum loop (i.e. your own home made sample of the amen loop). Chop it up beat-slicer style like you’re used to. Recreate the loop via the pattern and the slices so that it’s rhythmic properties are identical to the original, but are quantized to remove human inconsistancies with the drum hits. Now, render that to sample…then have fun with the 09xx command because it will accurately trigger each hit on time without any issues of starting in the middle of hits and you don’t have to remember a whole lot of numbers…
It should turn out that (assuming you’re using the non-jungle version…i.e. the first measure of the whole amen):
0900 start sample, first kick
0920 second kick
0940 first snare
09c0 second snare
09e0 last ride
If you don’t quantize, you’ll end up having things like:
0942 first snare
it’s just harder to keep track of that.
Keith303 and others expressed delight in simply placing a trigger for the quantized loop every 8th note and just changing the 9xx command all the way through the song…it’s easy rearranging of the loop. If it’s quantized before hand, it will always sound good, however because you’re not using chops, you can add in things to taste, such as timestretch, strobe muting, ‘rewinds’ (combo of b00 and chained 1xx), etc.
Hopefully, that helps you out a bit achieving whatever effects you’re after…and don’t forget, you can still incorporate the subtle snare/kick changes using this method as well.
