Using that form isn't very accurate though.

Hmm, I thought that it resetted the note playing, ie: it would go through
the ADSR loop again? I could be wrong.

Hmm. Have you tried this on a new SID? That feature/bug might no longer be
in service...

Sure sure :)

Well, that ain't so hard. Search through the code for a STA $D418, and find
out where it's getting that value from. Most SIDplayers will have an ORA
before it, to put the volume level and the filter level in together. All
you need to do is put this exact code into your sample player.

I have them seperate, as sometimes I don't which to lose any code that's in
the drive... ie: when I was testing my IRQ loader, I would send something
to the drive, reset the computer, then look at drive memory via the AR
monitor.
I'm considering putting another 24 LED's in to reflect the status of the
Address and Data busses... Though I think all I'll get are flickering
lights :D. Also, a few switches for ROMH, ROML, GAME, IO/1, IO/2 etc.

Oh yea of little faith... ;)

Ok, it's not well documented, and I only have JCH's V15 (I think), and DMC
1.2 (or 1.3 if you include my mods :). I reassembled them myself.

Well, I'd like that actually. I want a good player, and none of the ones I
have cut it...

Ok, but let's try and finish it first, eh? =) Hey look! An actual Menace Utility!

Eeek! What a mess! Oh well, not exactly what I'd call FTP, but hey...
