All non MPC Akai's should be able to read AKP files. From the S950 on, Recycle would create AKP files and then you could easily import them via SCSI into the Akai samplers. I think MIDI too, but I did via SCSI.
I used to own an Akai S1000 and I would chop the loop inside Recycle and then export an AKP file from Recycle/Mac via SCSI into the S1000. Really cool stuff.
The MPC series is not really supported by Recyle.
I use MPCPGMMAKER on my Mac. Create Wav files out of the chops and then create programs in MPM. That sounds crazy when I write it!!!!
Actually, this sucks sometimes, but if I really want a chopped loop fast, it works.
I still think the best way to do it, is to do it all in the MPC. Recycle is cool, but with no support for MPC's...do it all straight into the MPC.
