I just finished a quick second test. This time I combined the CPS with my Acoustic Image Corus - a 22 pound, but powerful amp. I played a lot of differnt bass patches of the Ketron SD4 through vArranger. I don't know if my ears played a trick on me but I thought the CPS handled all the bass sounds well to the point where I can use it as is in many situations. When I combined the Acoustic Image Corus, of Corus, the Oberkrainer bass of the SD4 was plenty fat to satisfiy any German or Slovenian.

While at it, I played some multi patches that Dan created for vArranger. Two layers of piano - one piano set at 48L and the other piano at 48 R. I muted one piano at a time. It was interesting to notice the stereo depth when playing two pianos.
