I was thinking of buying Scaler 2 iOS version and I just downloaded it to try. It’s v1.5 and I’m on iPadOS 16.2 running on a 12.9" 2nd generation iPad Pro. The first thing I tried was the ‘detect’ function, but it doesn’t display the detected notes correctly (section A). If I play chords, the chords gets displayed correctly but the single notes are still clipped. This problem doesn’t happen on my 10.5" iPad Pro.
Thanks for reporting, we will get this fixed.
