[Jsynthlib-devel] matrix6 and other dev things

[Sean S. <Sea...@Su...>]

Hi,

Is anyone working on Matrix6 and/or Nord Lead enhancements? If not I 
might be able to sign up to do some.  I don't have any Java or C++ exp. 
but I do a lot of C programming and know some people at Sun.  Of course 
I don't have much time but who does?

I also appreciate the opensource nature of this project, and think it's 
great that you wrote this program for people to use wihtout trying to 
gain (man I love GNU sometimes).

If you're interested in the details of my testing then read on - I'm 
away from my studio at the moment but I did some testing with the 0.18 
jSynthLib and saw the following:

This is all dome on Mac OSX 10.3.4

$ java -version
java version "1.4.2_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_03-117.1)
Java HotSpot(TM) Client VM (build 1.4.2-34, mixed mode)


Testing Conducted on a Matrix 6 ->

Strange behaviour + enhancements:

	- Main Window - drop-down menus tend to disappear and have to be
	  		reselected to get at the menu contents.
		      - would be nice to be able to type the patch
			number or select it from the list (faster).
		      - turned my trash icon into a java icon...
	- Edit Window - sometimes the sliders don't appear.
	  	      - values cannot be entered via text in the boxes.
		      - values seem to do what they should on synth
		        after being stored (good!).
	- Bank Support - I could look into adding it if I knew the
			 format, I could probably use the 1000 as a
			 reference and compare to the Matrix6 dump using
			 a hex editor.
	
	- Patch Get   - recognises the patches as being from a Matrix6		
			(good!).
		      - Matrix6 only sends sysex on MIDI 1 for some
			reason (synth issue/feature).
		      - the Patch Name is all unrecognised characters.
		      - changing the patch name sort of works (as long
			as all capital letters are used).
	- Patch Edit/Store - Modifying the parameters seems to work.
			   - the click option for DCO's does nothing (no
			     sound, is synth issue?).
			   - the DCO source check boxes should be
			     exclusive not additive (wave + pulse +
			     noise) - I think but maybe I'm wrong.
	
	!!! - after getting a patch (sucessfully) I can send it to
	      Matrix6 (sucessfully but using MIDI ch 1 again).
	    - can edit the patch (but see some strangeness as above).
	    - can still send it to Matrix6 and it seems to work OK.
	    - but trying to 'get' the sent patch has problems JSynthLib
	      tells me that it is not in Matrix6 format but it's
	      "probably an Oberheim patch" (I guess Oberheim used
	      a weird format).  So something is not working right.
	      May just be the PatchName but I'm not sure yet.

Nord Lead ->

	I see that only the edit buffer of slot1 is used for the
	patches, would it be useful to have a setting in JSynthLib that
	will send to any slot?  I think it's just a field in the systex 		data 
that picks the slot.

	In the Nord L2 manual the sysex info says the data can be sent
	to the edit buffer or slots 1-4 (via values 0-5).  I'll check
	which one JSynthLib uses but I think the 0 (current edit buffer 	
	is likely what it is).  Was there a problem using the slot
	numbers?


So perhaps I can contribute.  I know anything about Java dev but I think 
all the basic tools (javec etc.) are already in OSX so that's a start. 
I have also grabbed a copy of your programming ref. page.

Thanks again and sorry for the very long mail.  (PS I just downloaded 
the .20 version and will try all this again once I'm back near my gear).
