Hi guys,

I'm using a mpc one, running v3.4.1.

I've been working on a project saved to my USB drive with reasonable success apart from the known issue of clicking and popping each time I move to a new sequence.

I cut up a sample and assigned some to pads and noticed suddenly the pads, regardless of what track I select will trigger every track at once giving me a nasty buzzing noise and changing the sound of each track.

I confirmed this by looking at track mix and can see volume rising on each track when I'm pressing the pad. I've rebooted, saved the project as another name on USB and created new tracks, but nothing works.

New projects don't have this problem (yet?)

Wondering if anyone else has experience of this, if there's a workaround/fix or if this is already known.

Thanks in advance.

Is that a typo or are you running the older beta 3.4.1? You should update to 3.4.3 first, see if this resolves your issues. It's also possible that the 3.4.1 project is corrupted and maky not work correctly in the full release version, I experienced many examples of weirdness with projects made on 3.4.1, those projetcs just had to be recreated (menu > save > tracks on individual tracks and then re-load them into a new fresh 3.4.3 project)

It's a typo I'm running 3.4.3, apologies.
