I have uploaded a text file describing all the sysex messages the Kiwi upgrade could implement. Before things settle down it does not contain the parameters/bye mapping tables. It only describes the generic format of sysex messages.
If any of you is a sysex geek, feel free to take a look at it and give feedback.
I have tried to stick to Mks-50/70/80 way of implementing sysex. I have just simplified their handshaking communication protocol and added a request with code $2x matching each dump message with code $3x.
