Hiroo,
Greetings!!
I'm not sure I understand your message. I don't think
the problem is in the SysexSender but rather in the
SysexWidget.sendSysex method. To restate my original
message, first SysexWidget.sendSysex calls my generate
method. When the call returns, SysexWidget.sendSysex
calls setMessage(sysex, sysex.length). Because
setMessage expects a valid sysex string and not a CC
messages, it throws away the CC message and just
returns the 0xF0 and 0xF7 sysex delimiters.
Are you suggesting adding something like the code
snippet you sent to the SysexWidget.sendSysex method?
I suppose you could do something like check the first
byte of the data and if it's equal to 0xF0, call
setMessage, else have it continue through a case
construct and test for the various other types of MIDI
data. Is this what you're suggesting?
Jeff
