What is it?
Lemux is a collection of (GPL) LADSPA instruments based on devices from the
openMSX emulator and other sources (e.g. sidplay2).
It is long from finished, but some instruments are already very usable.
I only tested them with alsamodular, and I'd love to hear from people
who try them with another LADSPA host. Any other feedback is also
highly appreciated.
More info can be found at the website:

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.
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...
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.
Keep up the good work.
ciao

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

Ah, I didn't read carefully: I thought, all that was built was
supposed to work. Nevermind.

There are different output ranges in use. Especially if you once used
Csound this is annoying. I now looked, what ladspa.h has to say about
this. At the "typedef float LADSPA_Data;" it says:
For audio it is generally assumed that 1.0f is the `0dB' reference
amplitude and is a `normal' signal level.
So with LADSPA signals indeed should have a 1.0 amplitude at full
volume.
