Mark, although you are right about the 2600 being much inferior, I don't want to mislead you. It does have custom sound memory. It does not have custom style memory. You don't really need panel memory banks 1 thru 10 nor custom style memory if you use the SD card the way it was designed to be used. Sound edits are different so sounds are not the same with the two keyboards. Once a style has been edited for the 2600, it is OK. BUT, the limit of polyphony is a big issue for me, as is the limit of foot switches.
