Yeah, it can't be done.

It just means I had to modify the way I create programs a little. Not so much of a big deal.
I have read heaps about the JJOS now and as I am chopping in Recycle there isn't much I feel I miss - if I was using nothing other than the MPC that would change though. One thing that pissed me off about the Akai OS vs the JJ is the metronome volume can be adjusted in the JJ - I ended up just making a program for one so it's fine, but stupid oversight by Akai.
I guess the only complaints I have, is the fact that track mutes can't be recorded internally - pretty sure the 4000 can do this.
Lack of pad grouping, but it's a minor gripe.
The purging of any pads/samples not used in sequences.
All up, this has to be one of the most inspirational machines I have used for beats. So fast and just plain fun!
Some cool MPC vids on Youtube...
