It seems to me that a company producing a brand new, up to the minute piece of equipment would have it able to be addressed by the newer interfaces.
The problem seems to be that the sysex file is sent to fast for the unit to accept it correctly.
I'll worry about it later. The unit is working the same as always, but it would be nice to have the latest upgrade.
It will be interesting to see how long it takes TC to respond to my support emails, if they ever do.
