Hi,

if you wanna good test to hear the shuffle , make a simple kick drumloop 4X4 style on your computer or with a sampler and sync your 909 and listen , and you should hear the syncopation.
As for the flam, line a few snares up and listen to the change as you increase the flam from buttons 9-16.

As for recording the loops I usually make a full track with all dynamics and then make samples of them . ex.

Loop1: Kick+Snare+Toms+Hihats+Ride
Loop2: Kick+Snare+Toms+Hihats
Loop3: Kick+Snare+Toms

and so on... as well as I record down unique drum sounds I've made , just in case.

the reason I do this is because I can change the loops quickly in sequencer/sampler quick and as well I can always return to the patterns later on if needed so.. cause with working with analog stuff .it's hard to reset stuff up all over again . :lol:
