MPC 2500 JJOS XL: Faster than 300BPM?

Hello! I wonder if it's possible to make a sequence run faster than 300bpm?

The reason why I want to is because I'm doing a lot of drum & bass in 160-180 bpm, and it would be so much more simple to make rolls in 1/32 in the grid edit mode when the sequence is running at double speed, making it possible to edit every 32 step in grid edit.

I always do this way with tracks around 140 bpm, that will say working in 280 bpm to program rolls more easily. But since it seems like the MPC 2500 can't run faster than 300 BPM, I cannot do this way with sequences running faster than 150.

If not, do you guys have any tips on how to work around this? At the speed of 160-180 bpm it's very hard to time on point and get right duration with the note repeat at 1/32...

Thanks in advance

program / record the roll in 'normal' (or i guess half) time.
go into step edit, note the difference in time between the first two hits.
copy those notes.
paste / overlap those notes starting at the halfway point between the first two hits.

i admit i dont know if that's how jj works but the idea should be the same.

example
o...o...o...o...o...o...o... <-that's your 'halftime' roll.
copy it, and paste it between the first hits...
(o is 'original' c is for 'copy')
o.c.o.c.o.c.o.c.o.c.o.c.

I wouldn't recommend doing a beat at 300bpm by the way. The last time I tried a fast note repeat at 300bpm I got an instant freeze.

Just noticed that the step <> keys takes .12 step, so by using them i can make 1/32 rolls in the original tempo.

Thanks
