Thanks. I’ll take some photos later.
I don’t mind which one’s master to be honest, but in the past, when I used to try and sync 2 Op-1’s with the Mpc, the OP’s stay in perfect sync with each other but the Mpc drifted. This was over usb though.
I’ll check a bit later if the MPC can receive transport without clock.
Cheers!
The octatrack stays perfectly locked into the MPC in my experience. The key is to have the OT receive transport and not clock, and set the tempos to match. This may or may not work for you, but it works rock solid for me.

I’ve just switch on ‘Sync’ on the Mpc’s output port A and it momentarily worked. But now the Mpc’s making a short burst of sound and glitching out the beginning of playback. In fact the sequence can’t get beyond the glitch.
So basically, if I press play on the OT it also starts the Mpc. If I stop playback from the Mpc and then press play on the Mpc both machines freeze/glitch.
If I unselect transport send on the OT, the Mpc stops glitching, but obviously can’t received transport now. I want the convenience of using transport on both devices depending on which one I’m working from at any given time.
Do you have the OT sending clock? And is the MPC input set to sync as well? You don’t want either of that.
If I don’t send clock from the OT it won’t start playback on the Mpc.
So you have the Mpc sending clock to the OT?
With your settings are you able to send transport from either machines?
I’m not sure your gonna be able to send transport from either machine. I’ve never heard if it working like that before, but that could certainly just be my own ignorance.

It’s just odd that you can activate/check both send and receive for Transport on the OT at the same time. Why would you not be able to do this on 2 different sequencers.
But as I think about it’s perhaps not a big deal, as I’ll probably want to work on the different machines in isolation at times. If I’m continually triggering both when trying to concentrate on one machine, that could get very annoying.
i control Stop/Start on MPC One from my Pyramid (which is sequencing all my MPC programs/tracks externally). just set MIDI Out Syc and Stop/Start on the Pyramid to “on” and set the MPC to receive clock sync
I know how to make the MPC receive clock/transport. I’m just not aware of how you’d make the MPC the master and also receive transport.
And out of curiosity I’d be interested to know from a broader set of users which box you have as master for clock. Specifically those using an OT/Mpc combo.
Cheers!
Fwiw, the reason MPC is master for me is because you can’t use its looper when it’s set to receive clock. That’s how I get my external synths audio in.

Ok, good to know.
With the 1000 I always made OT the boss. When I did, changing patterns would correctly change sequences on the MPC. When the 1000 was the boss the OT suffered from that “1 bar late” issue. I don’t think I’ve tried it with my Live2 yet though, but I’d expect similar results.

If you want to start/stop/reset the MPC’s sequencer remotely, but keep it as your master clock, you need to send it the following machine code messages…
Apologies for the framerate garble, it’s a low-res pic of my computer screen.
Cheers!

Your only options are as follows:
- set one as master and the other as slave…
- send both boxes clock and transport, independently, from a third-party device (i.e. E-RM)…
- run them unsynced, and get good at pressing play in time…
I actually prefer the latter, and the Octatrack is perfect for that, because it allows you to nudge its internal clock manually, in real time, like syncing turn tables. Both the MPC and OT have stable enough clocks to run unsynced alongside each other for quiet a while before needing a nudge.
Cheers!

Thank you.
I’ve given up for now. For such a simple setup it’s going horribly wrong. Sloppy sync both ways and mad temp fluctuations.
It’s bizarre as both machines are using fresh/default templates, so there shouldn’t be any hidden anomalies.
But at the very least I’ve established which machine is going to be my main compositional environment (OT).
Thanks, people!
If you’re running MIDI in both directions, maybe trying removing the upstream connection, to see if that doesn’t fix whatever weirdness you’re experiencing. That would at least eliminate the possibility of a MIDI loop or feedback.
And the default templates don’t include global preferences, so I’m sure there are things to examine there too, with regards to sending and receiving MIDI messages, clock, and transport.
I’ve never had an issue syncing the OT to the MPC or vice versa.
Cheers!
The glitches probably mean that the clock messages are running back and forth, overloading the midi bandwith you have. So make it one directional first and try to go from there step by step.
Not a proper teardown but Here’s some picture of the mpc x guts. If you’re just replacing the buttons and not the tact switches looks like you just need to get the face plate off.
