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

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

Hiroo,
 
About your question, "Does not SysexMessage.setMessage throw InvalidMidiDataException? It's interesting.":
You're right, it does throw InvalidMidiDataException, but the setMessage call is in a try/catch block and the catch block just calls ErrorMsg.reportStatus(e).
 
About your comment, "The method I sent you returns an array of MidiMessage (if it works as I expect:-)). You can send each of them by using driver.send().":
Thanks, I'll give that a try. I'll let you know how it goes.
 
About your question, "How did you list up the lots of drivers of the kind?":
I'm doing my development on a Mac using the XCode tool. XCode has a few nice features, one of which is a find/grep function that lets me search through whole projects or frameworks. I just searched the Synthdrivers directory looking for the string "SysexSender" to see which drivers were subclassing it. But then I only actually looked at about 3 or 4 of them and none of the ones I happened to look at were sending CC messages. Maybe I should have looked at little harder?  
 
Thanks,
Jeff

Jeff,

I assumed that SysexMessage[] MidiUtil.byteArrayToSysexMessages() was
used and I made a replacement for it. Sorry for confusing you.

Does not SysexMessage.setMessage throw InvalidMidiDataException? It's
interesting.

The method I sent you returns an array of MidiMessage (if it works as I
expect:-)). You can send each of them by using driver.send().

But as you see, the code which convert byte array into an array of MidiMessage
is very inefficient. Driver can easily send short messages without
using SysexSender by using one of Driver.send() methods now.
I started thinking that it might be better to fix drivers which use
SysexSender for non-sysex message. How did you list up the lots of
drivers of the kind?
