Hi, Terry, Bert, Al, Scott.
I heard from Michael Bedesen, and he said as follow:
This freeze is often caused by opening cakewalk while the T2 is connected to the pc. By default, cakewalk sends a local off command(you can see it in function/midi/edit/transmit)can be turned off by modifying one of the ini files. (Modify the TTSSEQ.ini file so that sendlocal . This line determines whether or not cakewalk should send a local control off message during startup.
But cakewalk also sends something that messes up the accompanimant. .This sensitivity is unique to the T2
Because the solution to the second program is unknown. When the stystem hangs, the best is to go to function/utility/system, reset and check midi setup(if you have not disabled off commands and system setup. Then execute the resets. It is much faster than rebooting.
