Scaler 2.7.2 on Logic Pro crashes

Of course running Logic in Rosetta.

Attached log.

Hi @allaboutseb

Thanks for reporting, this didn’t come up in our testing. We will have a look.

Scaler 2.7.2 has been crashing on me too. Rather randomly… Maybe once every 4 - 6 session… Also it sometimes seems to ‘forget’ that I have loaded my own midi chord progression, (of legato notes, no overlap) I sync Scaler to Logic Pro, It may work fine a quite a number of times. but then it sometimes stops registering the midi chords… I have tried both dragging the midi chord file into Scaler, or playing the Logic midi chord instrument track. with Scaler synced to logic and it determines accurately what the chords are too. Now I am a new user, so I don’t know if I’m doing something wrong

Here is a link to crash report

Crashes all the time in Logic for me too. Getting to the point where I won’t use it.
