When it comes to non arranger keyboard play..or with the accomp turned off..accept drums...I find it comfortable for me..I like to play left hand bass and piano...as we did in the "old " days..
I like to sit at the piano...but basically for my own enjoyment...voicing different chords to standards...I can sit and play piano for a couple hours, but after that I am ready to move on..I am not comfortable gigging piano...and the same with the accordion..maybe a couple hours..same situation with B3 organ..
Though still an arranger, My favorite playing choice is left hand bass with drums..with piano and color sound with the expression pedal...just like we did with SH101, JX10 and TR707...
The variety that a great arranger gives me..is unsurpassed...just turn off some bells and whistles once in a while..
