Hi there!

I’m trying out scaler and have a problem with the scale lock.

I set up a chord progression at the bottom which I can then trigger on my midi keyboard. That works fine.

The problem is that the notes played by my right hand (setting scale lock to white keys only) doesn’t reflect the last triggered chord.

Also, if I set another midi track to receive midi from scaler the triggered chords are ignored.

Is this a limitation of the demo?

Thanks in advance!

Hi @summer

there is no feature limitations in the demo, only a time limit.

What you describe doesn’t sounds like the normal behavior, we will run some tests on our side to check this.

Thanks for reporting your issue,
