Midi
in edit mode it is possible to edit all parameters USER-patches using CONTROL CHANGE.
The list is printed on the machine and it is not very standard - this is indeed a very nice feature, sadly, the Midi buffer quickly chokes freezing the whole machine.

Review
OK: -rare- control change edit -12 DCO
NOT : - sounds thin- bulky- edit interface - Midi crashes -limited
"well nice, vintage, rare... OK a lot of SSM - so? but sound is nothing so special for my taste - a kind of poly61 but much more esoteric. Love the chorus."
