I thought so.
With Roland pretty much out of the arranger game, I don’t see why its former competition don’t snap up some their better ideas, like now everybody and their uncle having a chord sequencer now.
The thing about playing piano is, you spend a lot of time with the sustain down, moving up and down the keyboard, making runs and arpeggios, playing passing notes etc.. but it’s rare with the sustain down to play five notes simultaneously. But three..? That’s pretty easy, and it will send your chord recognition off on a wild goose chase!
Try to contact your manufacturer, see if you can’t get them to add this. It’s a fairly simple code exercise, nothing as complicated as good articulated sample sets, or even the chord sequencer, but nothing I’ve played in 30 years of arranger use ever allowed me to play pretty conventional piano until Roland’s ‘Pianist2’ mode.
Roland’s shortcoming in this area was, they never had a rootless chord mode, so trio type playing isn’t as well done. But play less jazzy, and it tracks pop and rock playing flawlessly. If I want to do rootless voicings, I’ll turn on the chord sequencer and record the head with more straight ahead pop voicings, set the ACC to mute any piano stuff (best is just bass and drums), then start the chord loop and move to the rootless voicings for the solos…
