Hello,
I made 12 scales on my MPD 226. I think it work with the 3 new MPD. Just send it to hardware with MPD Editor in a free preset slot.
Load in 3 free slot and choose the preset you want, all pads from each bank is in the scale, starting from C1 bottom left.
I use it with digitakt but I think it work with every elektron gear with chromatic sound.
The scale are:
Major (bank A)
Minor (bank B)
Jazz Minor (bank C)
Harmonic Minor (bank D)
Pentatonic Major (bank A)
Pentatonic Minor (bank B)
Blues (bank C)
Algerian (bank D)
Chinese (bank A)
Japanese (bank B)
Egyptian (bank C)
Spanish Gypsy (bank D)
