It looks like it is handling the midi channel assignments just fine since if I change the default channels it does change (00 01 02 – 0F etc) however I think it should be 30-3F etc (based on the sysex spec on pg 62 of the manual http://www.pallium.com/bryan/dw/DW-8000_Manual.pdf). The same thing seems to be the case for the tx81z, the strings are right except for the format ID which is 10 (sniffing another editor) and the ctrlr software is again sending 00.
Let me know if there is anything I can do to help..
Beyond that, everything does work fine in the standalone
