Crash when Lassoing Main Track [FIXED]

Scaler 3 Support Fixed
,
21

Clicking the chords individually is fine - it’s when an attempt is made to select them all by dragging from the top left corner.

Deleting Scaler 3.settings worked - I can now open standalone and can select all chords without a crash (even after changing the default ‘Felt Piano’ to Arturia VST. However, when I load my previous saved state (attached), the crash is back. This has 3 tracks (Main, Melody and Bass); I’ve only tested a fresh session with only a Main Track (no crash).

I hope this is useful.

Hi, I was demoing Scaler 3 and this happens all the time to me as well in any custom project any time I left-click and hold to select one or more chords (starting from the space after last one) in the Main Track on the arrange page.
Here’s the console report after a crash:

The original posters issue sounds exactly like my reported issue. Crashes both in standalone and as a plug in Logic (instrument and midi).

Also on macOS X86_64 here.

I have updated to 1.0.7 and still same problems. I have reinstalled a couple of times and have also pointed out that you should inform in your instruction that if you delete one of the paths in the users Library folder you will also delete your Scaler saved projects

Currently almost impossible to use Scaler for me. The computer is clean and only used for music. Scaler 2 never ever crashed and 3 have crashed it since day 1. Even corrupted Logic sessions when crashing.

I have reported this and sent all the crash logs I have to Scaler.

Hoping for a working version soon.

Best regards

I can also repeatedly trigger this crash in both Ableton and Reaper. I’ve loaded a chord progression user preset that I created, tried to select all chords on the main track in Arrangement mode in order to duplicate them all. What’s also weird is that I’ve already done this once, duplicating from four bars to eight bars of the same progession. The duplication of four bars worked fine, the duplication of eight bars consistenly crashes. Scaler Main track plus 3 more performance tracks are routed to midi channel 1 in Reaper. (As an instrument on a track)
In Ableton, Scaler 3 is loaded into a M4L Midi Send Wrapper

Running macOS 13.7.6, Scaler3 v. 1.0.7

Upon further exploration, in my crashing version, the DAW would crash when I selected the chord that had no performance pattern on the arrangement track. i.e. the Arpeggio track had no midi pattern in it.

When I add a pattern to this track, I’m able to select all the chords as normal. No crash occurs.

Hope that helps narrow it down a little more.

Hi all. This has been fixed in Scaler 3.1. Cheers.
