The Logic Off Topic list

Without knowing your particular synth, I can see what you are trying to
do is edit performance presets on the fly. The way most synths work, you
edit a performance  to the way  you want it, then save the performance
in a user bank, so that it can be selected later. What you really need
is a bank of single-voice performances and to set up the relationship
between them in your logic song along with FX routing etc. The
alternative is to use SoundDiver and access as many variations on
patches as you have the time to program , from a SoundDiver library.
Either way, its not easy to handle the interchange between patches in a
complex instrument without allowing some time for the changeover, which
is only increased if you use sysex. [sysex is far bulkier and neeeds
more time to be sent, and you could be waiting for several bars for the
changes to take effect].
 Far better to load all the performances you want to use on different
channels and change tracks when you want the sound to change [keyboard
splits are good for this]
 Maybe what you really need is a sampler though.
