Great!

Strange, it works out of the box for me. Maybe I have some
libsidplay-dev installed or something, which hides a dependency. I must
plead guilty for refusing to use automake/autoconf, because I used it
alot and it always ended up doing more harm then good, and anyway, the
source is supposed to be "selfcontained".

MUSICDrum for some mysterious way doesn't give any output. I still need
to dig into that deeper. Thats why it is listed on the website under
"not working yet".

Yeah, if [-1,1] is the "normal" output range, I should adjust all
plugins for that. I never programmed audio before, soo there might be
some more "obvious" mistakes in the code. Maybe that is because AMS
works with voltages :)

Just to be sure, currently "fully" working are:

SCCChannel (e.g. from Konami games)
PSGChannel (the standard sound chip from MSX)
MUSICChannel (the FM OPLL chip from MSX-MUSIC)

SID gives sound, but I don't get "nice" audio out of it, but I'm no C64
guy, soo that might explain it.

Thanks for the feedback, Joost
