Since we are letting it all hang out.
In the current band, we play a set which could include a couple of dance midi file playbacks, some arranger type assisted songs, and then songs where I play bass with my left hand and with the right I would be doing solo lines, string pads, and what have you.
I also mix the band as well. So for me to have 2 arrangers would help me in having the ability to have any keyboard at any time do any of the above mentioned.
Plus I figure why can't keyboard companies listen to the owners and manufacture their keyboards to our specs!!!
Amen
