Getting Akai MPC Mini Arp to sync to Live tempo??

[obxwindsurf]

Ok,

I have the Akai MPK Mini recognized through Live through the User Remote Scripting capability. I have Pad Bank 1 operating Impulse sample slots, Pad Bank 2 operating transport controls, knobs mapping to Macro Knobs and everything works just fine.

However when I set the MPK Mini to accept external sync (to sync its arpeggiator tempo with Live), and in the Midi Sync tab of preferences turn on all of input/sync/output on the MPK mini (in and out - doesn't matter), when I turn the arp on in the MPK mini and hold keys it plays nothing (indicating that it's not receiving sync from Live).

Any ideas?? (not a noob, not new to Midi or music production and not new to Live so please consider that in your response - if you have experience with this please reply - if you don't, I know your intentions are good, but if you haven't solved this problem you won't help - someone with an MPK Mini must have already addressed this problem)
