I have stayed out of this conversation as I have little knowledge about chord sequencer keyboards but I hope someone can help me understand. I watched the video and it looked like it took a number of presses on the touch screen to get a chord sequence. I have DLed a MIDI song, brought it into BiaB so the chords are inserted into the chord window, picked a style, then pressed generate. I can also have a BiaB demo song put into the chord window. IMHO, and I may be wrong about this, both processes are easy to execute and have thousands of styles to pick from in the styles window. Note that I can use both RTs or MIDI styles. Granted PGM could have a better filtering system for picking a style but to me BiaB is the better route to take. YMMV

PS - Steve this is no knock against you or anyone else into chord sequencer keyboards. I'm just trying to understand. Noted that you will need a keyboard along with BiaB so that is another expense.

Why is it that doctors call what they do 'practice'?
If flying is so safe, why do they call the airport, the terminal?

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
