I’m having my first issue with Scaler 2. I’m using Windows, Mixcraft 10 Pro Studio, Scaler 2. I’m sending the Scaler 2 notes out to an Arranger keyboard, voice Right 3, midi channel 4, the Yamaha PSR SX900 plays the notes almost. Here’s the issue: when I click on the chord with my mouse in Scaler 2 the chord plays perfect, but when i bind A or B to my controller keyboard (have tested 3 different controller keyboards). It adds m7b5 to random keys and plays some horrid chords. The Arranger keyboard shows the chords it’s being sent and I see m7b5 added to random chords. I’ve tried different controller keyboards as well as the arranger keyboard to trigger notes in Scaler. I can’t seem to figure this out. Any help is appreciated. 
In a last ditch effort to fix this, I uninstalled Scalar 2, then reinstalled it and reactivated it and the chords are playing properly now.
