A two line arrangement to crash yr OT

Been discussing the arranger a bit over in the OT feature request threads and while exploring it as a means to get better muting behaviour/other performance options I ran into multiple crashes.

If anyone wants to try the following 2 line arrangement on a fresh project (no samples or patterns needed)…

(Where B column setting is ‘pattern’ rather than a numerical tempo. The patterns can be any bank above A)

On my OT it crashes with the on-screen error when switching to the second line.

After post-crash power cycle the tempo is set to 30 and trying to switch to the ‘offending’ bank (bank C in this case) gives this message:

This same thing happened to me last week! Totally lost bank C too. Luckily I didn’t have to much put into bank C yet.

I wasn’t sure what I did but it definitely was something with the b column and setting the tempos to pattern. I think i manually set all the tempos in the b column now.

With the project above, next time I powered up it was bank A showing unavailable. Weird. It was all empty anyway as a test project - so I’m not sure if there was actual data loss (except original tempo)

I defined had data loss… could have been because the project and/or parts not saved. It freaked me out.

Hmm, good to be aware of as I am using the arranger primarily right now for the first time. Thanks for posting this thread.

I have done some looping of selected parts but I haven’t run into any issues yet.

I’m getting back into recently. It has some great possibilities. So far only tempo stuff has caused me problems

Is it only happening when setting for bpm row is pattern? I can’t test right now but I should be able to tomorrow.

Can workaround be by manually setting value for bpm row?

If so I reckon it must be something that crept in when pattern tempo was added in 1.40

That’s what I was doing when I crashed mine if I recall correctly it was after I “inserted” a new second row between the first row and an already existing row and went to the b row and changed the tempo to pattern… this was a week or so ago so I can’t be sure but pretty sure this is what I was doing.

That’s at least what I found while trying to replicate the issue.

Not with OT now but I believe you have to turn past ‘pattern’ to get to the manual bpms & I think that once or twice it crashed while doing that - the sequencer was running and I went into B column on the active row.

It crashed quite a lot, but I was trying lots of things. Now I can only replicate ‘reliably’ with the setup I posted above

Yes, might well be related to the introduction of the proj/pattern tempo feature.

Confirmed can reproduce on mk2


After reboot I tried manual bpm entries, and first row plays as normal, second row falls through straight to end.


@Patrik have you seen this?

Right! I remember seeing that now. Thought I’d put a crazy bpm on it. Didn’t have any trigs in place as I was just trying to replicate the crash at that point - so didn’t get to hear what it would sound like. I’m guessing it’s really just skipping that row…

Also - I think the first time pressing play after a reboot (and maybe removing the B entries) it stops on step 2. Playing after that it goes further

Pretty sure stopping on step 2 has been a symptom of a confused OT in the past

Not sure if this is the place but in terms of arrangement tips: I just discovered that starting an arrangement clears recording buffers. DOH

Not for me. Just double checked. Maybe you have patterns with rec trigs?

ahhh yeah one shotters. You Live and you learn. Having a blast tho, finally managed to route ableton into the OT.

When you „save as new…“, does it still show bank unavailable?

maybe strange question. but could you try again and have pattern P15 and P16 with something written in them? If this would not fail the same way it would proof one particular suspicion i have - knowing the arranger file format in detail.

blurbed my nerdy talk here…
