Exchange tips and tricks for the Akai MPC4000

Is there a way to dynamically adjust and subsequently integrate into a sequence the point at which a sample loops when triggered?

I'm working on an mpc4000 with the latest os update

thanks in advance

I don't think so. I suggested to Akai several years back to add in the
Modluation Matrix some more destinations for Sample Start, Sample End
Loop Start and Loop End but they chose to ignore it or didn't have the know how
to implement it.


Cheers,

Yes, but only through sysex which is a lot more tedious than sequncing the built in modulations. I recently picked up a MIDI controller that does sysex, and this is one of the first things I tried. It is VERY cool! I'll start a thread on this soon, but all the info is in the sysex doc.

The sysex string to set sample loop end is:
F0475F001E310000XX00000000000000F7

Replace XX with a 7-bit hex value 0-127 to get a value between 128-16384. The 2 00s before it are for more fine tuning (0-127) and the 00s after give you broader range (16385-2097152). The sample first has to be selected for this to work. If you do not understand how sysex works on there, I will be posting a guide shortly.
