The Roland system is good, it has merit. It's the easiest way (at least among those embedded in consumer hardware sold in volume) to play a broad selection of popular chord types without extensive training / time commmitment. It's undeniably more ergonomic than full-fingering, especially when playing seventh chords, and in certain keys. However it doesn't penalize you for playing all of the notes. Casio and Ketron have been using a very similar system, at least since 2015. It DESERVES to be proliferated because it makes some better off without making any worse off, and it's logical.

When I pointed all of this out to Klaus (who programmed a competing software arranger called Nimbu), he worked with me. We exchanged emails for a couple of months. He put the time in, and added the Roland emulation mode.

You are all trained musicians. What would a novice have to say? Or an engineer, or an ergonomicist who has studied the human hand? We don't use longbows or sailing ships anymore except for sport. And nearly every sailing ship afloat has a motor as backup. Our technology has taken us past the necessity of one tone per key. Finally it's SOFTWARE. Let's please be a little open-minded here!
