Hey everybody!

is it possible to use the MPC as a controller for transport-fuctions (play, stop, record) in the daw? so for example, if i press "play" on the mpc, the daw starts playing, if i hit "play start" the daw plays the song from beginning, if i hit "rec" the daw starts recording an so on.
Is that possible? I use logic 8...

thanks for your help!

there seems to be a bug in JJ OS's Sync-Out Mode if set to "Midi Time Code":

If you set your daw to sync with an external device (using midi time code) and hit play on the mpc (mpc's sync out set to midi time code as well) the daw jumps to position - 8 1 1 1 and stays there, wiggeling around a little.
I think this is not supposed to be this way, is it?


@ hyena, you can at least use the start/stop buttons of the mpc to control logic if you activate "Recive MMC" in your project settings -> Sync -> Midi -> Midi Machine Control

it's been a while since I tried to sync logic to my 1k, but I remember fixing that particular problem by changing the mtc start time to all zeros in logics preferences. Sorry to be so vague, but basically the problem is that logic considers 1:00:00:00 as the star of the sequence (bar 1), while the mpc considers 0:00:00:00 as the bar 1 position. So when the mpc sends the initial timecode, logic immediately tries to rewind an hour back. But of course logic can only go back 8 bars before bar one. So basically logic is trying to sync the time position whil also trying to play. Hence the wobble at bar -8.

thanks a lot, that sounds reasonable! Gonna try it as soon as i'm home :)
