Hallo,

Lemux is a collection of (GPL) LADSPA instruments
based on devices from the
openMSX emulator and other sources (e.g. sidplay2).
Wondergreat! I've been hopeing for some oldskool sid plugins for some
time... ;) Compiling it was a bit tricky: It was looking for
siddefs.h which I
created by running configure/make in resid, then copying it to the
top directory.
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".
I just shortly tried MUSICDrum and SCC in Pd using the
plugin~ external
where they did load fine, but whatever I tried I couldn't get sound
out of MUSICDrum. It gave messages like:
writeReg e,30
BD ON
HH OFF
SD OFF
TOM OFF
TOP-CY OFF
writeReg e,20
BD OFF
HH OFF
SD OFF
TOM OFF
TOP-CY OFF
so I suppose it basically is working. Maybe I use it in a wrong way?
I don't have AMS installed, maybe I should to test the examples...
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".
I just set BD volume to around 10 and frequency to
around 100 Hz, then
gave the BD audio in either a constant 1 as audio data or a const. 0
to turn it off...
I had more luck with SCC but the scaling of the audio output is very
unusual. Normally (== swh-plugins) I get output in the [-1,+1] level,
but SCC is about 100 or more times louder. Preset selection works, it
does make sound, just too much of it.
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
