[Jsynthlib-devel] Sending CC Messages and Disabled Edit Menu

[Jeff W. <jww...@ya...>]

I use a number of subclasses of SysexSender in my
editors to send CC messages to the Pod and Bass Pod.
This worked fine in verision 0.18 but ever since I
started working in version 0.19 it just sends a series
of empty sysex messages (0xF0 0xF7). I'm developing on
a Mac and I used a program called MIDI Monitor to
verify this.

This weekend I finally got time to sit down with a
debugger and try to figure out the problem. I found
that the generate method of my SysexSender sublclass
is being called by the SysexWidget.sendSysex method.
When the call returns from my generate method, it
calls setMessage(sysex, sysex.length). It looks like
setMessage expects a valid sysex string, complete with
0xF0 and 0xF7 delimiters. Apparently, if setMessage
sees anything else, for example a CC message, it just
says, nope, this isn't valid sysex so I'm just going
to send 0xF0 0xF7.

Looking at other drivers that use subclasses of
SysexSender, I noticed that a lot of them send sysex
for this purpose. But this really isn't practical for
the Pods (the only other option is to send complete
sysex records and the Pods tend to choke if you send
too much data to quickly). If anyone's planning to
address this issue, I hope this helps.

Also, I mentioned a couple of weeks ago a problem I
was having with version 0.19 where the Edit... command
was disabled when I select a patch in the library
window. I received a reply from Torsten saying he had
fixed the problem and that I should try the lastest
version. I've tried several new versions since then
and I'm still having the same problem. For the time
being I've had to temporarily wire the Play command to
bring up my editor (the Pods can't "Play" patches
anyway). So far I haven't been able to track down the
cause of the problem. I still have a couple of ideas I
haven't tried yet but if anyone has any insight into
this, I sure would appreciate hearing from you.

Thanks,
Jeff
