Remember that piece of junk that I rig on every desktop which still has
some PCI card slots anyway? If you don't, I'll tell you once more: the
Yamaha DB50XG piggyback. I know it's not easy find those nowadays, but
there's always that auction sites for you to try. Moreover the hosting
sound-cards which exposes a Creatine Labs Waveblaster daughter-board
expansion port, are no easier too. Ah, the good old nineties...

Never mind, so here it goes again:

 QXGEdit 0.1.0 has fallen from the attic

Note these binaries probably work on Fedora too:
 http://downloads.sourceforge.net/qxgedit/qxgedit-0.1.0-2.rncbc.suse112.i586.rpm 
 http://downloads.sourceforge.net/qxgedit/qxgedit-0.1.0-2.rncbc.suse112.x86_64.rpm 

The latter "worksforme" in Fedora 12:

> sudo rpm -ivh qxgedit-0.1.0-2.rncbc.suse112.x86_64.rpm

This synth is a daughterboard card for http://en.wikipedia.org/wiki/Creative_Wave_Blaster ... Well reviewed ... http://www.soundonsound.com/sos/1996_articles/may96/yamahadb50xg.html and still available http://cgi.ebay.com/Yamaha-DB50XG-DB60XG-Sound-Daughter-Board-SW1000XG-/200458972918 . 

This program looks nice enough that I almost want to find one of these cards and daughterboard for sale cheap on ebay. I wish I had patch editors on linux that look as nice as qxgedit.

PS: Anybody know whether this can control other Yamaha GM chips -- like the one in my Suzuki Q-Chord or Yamaha DD-55??
I did a quick test and although the lights on the midi box flashed, the sound didn't change any. That's why I tested this out in the first place.
