Created with the Roli Seaboard MPE keyboard controller in mind and as an exercise in exploring Atelier with MPE. However it only does one octave of an Ionian scale (C3 to C4 white notes only, or just the black ones on the Seaboard :-) ). Y axis Slide (CC 74) controls the first GrmComb mix. The Seaboard X and Y controller (CC 113 and 114 respectively) controls the GrmTime chorus mix (eight snapshots to choose from) and the GrmComb reverb/echo (eight snapshots to choose from).

NOTE: Using the Roli Dashboard the Seaboard is set to only one MIDI channel. This stops notes moving between MPE channels and breaking things. This restricts the notes to MPE channel 2 and the slide (CC 74) to MPE channel 2. This means a global slide and not individual slide values as per true MPE. The X and Y controller CC are on channel 1.
