[Jsynthlib-devel] BankDriver requests

[Steven S. <ste...@co...>]

Greetings -

So far, I've found that if I take the time to compose an email to ask a 
question to the group, the process of formulating the question usually 
lets me find the answer myself.  Not so with this one.  I would think 
that a bank driver requests a dump of the entire bank to store as a 
patchlib, but the code looks like it looks for a single patch from the 
synth, not from the big dump.  Then again, when requesting a patch from 
the bank driver, I can't select a specific patch.  What exactly is the 
purpose and expected behavior of a bank driver?

Also, my (Korg Triton) device and single driver are working.  Should I 
check them in or wait till the editor is done?

Gracias!

Whoops - spoke to soon.  I can request any patch from the synth and save 
it in a patchlib, but when I try to store a patch from a patchlib to the 
synth, it grabs the GM patch (bank G) at patchNum + 1 and saves it to 
the bank I specified.  If I then try to play the patchlib patch, it 
plays the GM patch.  What's up with that?  I'm hoping this is familiar 
to someone with some experience at writing synth support who can show me 
the error of my ways.

Well I might misunderstand you problem.

The only problem here is "when I try to store a patch from a patchlib to the 
synth, it grabs the GM patch (bank G) at patchNum + 1 and saves it to 
the bank I specified".  In other words, store command sends a patch
which is next to the patch specified.  Am I correct?

Correct-sort of.  I am expecting it to load the patch that I have 
highlighted in the patchlib, but it is getting a GM patch from the 
synthesizer and storing it instead. Here is a more detailed example:  
 From JSL, I select new library.  From 'unsaved library', I select 
Patch->get.  From that dialog, I choose Bank A, patch 27.  Patch A-27 is 
retrieved.  I highlight the patch and select 'store'.  From the dialog I 
select Bank E, patch 9.  Patch 10 from Bank G gets stored at Bank E, 
patch 9.  Obviously, its only doing that because I must be telling it to 
do that, I just can't see where I'm telling it to do that.  Any help 
would be appreciated. 

Do you think a different list for synth-driver development might be 
helpful?  Issues like the very hard to decipher Midi Implementation 
documents could be dealt with there along with how to use them in driver 
deveopment.  Just a thought, in case the core developers prefer not to 
deal with these issues.

Perhaps you've stumbled across the 'copy patch' command instead of the 
'upload patch' command?  Or maybe the synth mangled the sysex it sent 
you so that when you send it back, it doesn't work.  Only suggestion I 
can think of is make sure you have the right command, and make sure the 
bytes are correct.

If you request a big dump to your synth, the synth will return big dump.

I may be misunderstanding your question, but let me try.  The methods BankDriver
(IBankPatch interface) do the job.  You may have to override some of
them.

I can check-in your working driver.  Editor is optional.

For your single editor problem, I recommend you to use Windows->MIDI
Monitor.  Using debugger may be a good way.

Would Windows-MIDI Monitor be a windows program?  I'm working in Linux, 
not Windows.

My question about the bank driver though, is it intended to process an 
entire bank?

Ok - I see what you mean - yes I've been using that.
