It is good but things can be improve
I use it with PatternBud+BrainBud. It is able to change the key. However, this only subject to the on screen keyboard of ScaleBud, but not my own midi keyboard (actually it is a 4x4 Drum pad, mapping with note 1/3/5/7 of different octave making sound like a chord) For example, when I am hitting a C3 note in every beat, the BrainBud changes from C Major scale to G major scale. As a result, my notes C3 is still keeping as C3, but not transposed to G3 which is i expected to be. That means the C3 is not mapped to the First note of the scale and so on. I hope this can be achieved as this help as it help generating pattern with any controller with non piano keyboard layout
