looking for troubleshooting ideas JSynthLib/Ubuntu/Matrix6r

2011-11-10 by Jonathan Carbody

Greetings Oberhiemers,

I have a question: I recently dusted off my old oberheim matrix 6r and hooked it up

to ubuntu 10.04 with a Edirol UM-1SX MIDI Adapter. I got the JSynthLib 0.20

and ran it. The program seems to run, but it's not controlling the synth. The midi

cable is connected properly because I got Rosegarden talking to it. Sequences can

be recorded and played back. Also if I boot up Windows XP I can run MidiQuest 10 XL

and (it's buggy) but I can edit. So I think the hardware ports are working properly, but

what's wrong? Maybe I'm missing something in the Java Virtual Machine to talk

to the hardware? A java driver or something? I'm running ubu 10.04, with

the sun jvm 1.5 or 1.6 which I thought had the midi drivers built in.

I'd be grateful for any troubleshooting ideas.

thx,

JC.

is there a software switch in the M6R to enable sysex?  i know that the mks-70 needs to be told to see this info every time it's used and these are both 'early' midi and poorly implemented to boot.

Greetings Oberhiemers,

Hi, I've done a little more testing. I booted up into windows xp

to see how JSynthLib behaves, which, from the looks of it, is the

same as on Linux. In both cases I startup the program, open the

midi monitor window, and I can get a patch from the synth and load

it into the program. The midi monitor window seems to reflect the

messages coming and going, it looks like it's working.

JSynthLib sends six bytes, f0 10 06 0a 00 f7, (not sure what this is)

then a program change which is reflected on the synth, then 7 bytes,

f0 10 06 04 01 00 f7, which must be the request to send patch,

then the program receives 275 bytes, f0....f7.

I can paste the sound into the library and open the edit window now.

If I move controls in the JSynthLib editing window, the messages appear

in the midi monitor, but the the synth sound does not change, nor

does the synth show any signs of changes on its blue LED display.

If send a note on from the JSynthLib, the note does play, so the

midi connection is working. Also, midi system exclusive is "ON"

in the Matrix 6 module. The synth is running software version 2.13.

I checked the program outputs byte by byte with the young monkey

webpage (description of M6 sysex implementation) and everything

looks to be as expected. I can't explain why MidiQuest on Windows

works (partially) but JSynthLib on windows and on linux does not ;

work... Does anyone out there have their Matrix 6 working with

the JSynthLib editor?

thx.

JC.
