Midi keyboard
https://musescore.org/it/node/303744
MuseScore has an exceptional compatibility and I would say also perfect with the KETRON SD9 arranger keyboard! MuseScore will drive impeccably (Mixer, reverbs, pan, articulations, dynamics, embellishments, etc.) everything we write in the score and play will be the superlative "sounds" of the Ketron SD9! It 's 2 days that I have the aforementioned keyboard and I must say that I have done everything to "stress", in vain, both MuseScore and Ketron but no problem!
