Re: [Jsynthlib-devel] Driver writing help

[Daniel L. <soc...@ma...>]

Woops, sorry - I went off the thread and back on with my replies.

The XML interface looks cool, I noticed there's another opensource project =
doing patch editting using XML in it (I presume for the synth description).=
  Might not be the worst idea to have the same XML format, then you could d=
ig from both worlds of Drivers for, perhaps, more synths (SynthDescription =
might be a better word over drive.. or SynthInterface).

They're at: http://synthed.sourceforge.net/

I guess support for my weird Yamaha S80 interface would be nice, sine I'd g=
uess the Motif series uses it, and from the docs I know some others use it.

Which is multiple values get crammed into one sysex string - E.G. There's a=
 13 byte string for an oscillator and some parameters, then a 29 byte strin=
g for the Amplitude, then a 27 byte one for the pitch, and so on.

I guess I'm going to make sets of Model/Sender pairs for each of those for =
now... and work from there.
