I am currently playing my sequences into my Korg 01w/pro, and am using both banks of 100 programs, [using controller 32, values 0 & 1]. I would like to be able to change to a synth module and not have to change all the program changes [and banks changes] in my sequences. Does anyone know of any current Roland or other modules or rack mounts that have 2 programmable banks , or know of another solution? Thanks in advance

My suggestion is forget about it.
It will be easier reprogram all the program changes than reprogram all patches of the new synth to sound closer to the korg.(Unless you have quite a lot of sequences)
To solve that kind of problem there was estabilish the General MIDI (GM or GS for Roland) wich will match the patches for different synths.
Once you have already recorded your sequence on a non GM synth it will be very difficult to have equivalent patch on another.
Not to mention that you may get problem with different curves of velocity for both synth, i.e., one track may play well one instrument but it may comes louder on the other synth, forcing you to reedit every sequence.
