It's still very useful for single speed though. I ripped a nice kick drum sound from a Mortimer Twang tune.
Anyone have advice for designing multispeed instruments/tracks?
]]>When I asked if updating SidDump to work with multispeed tunes would be difficult, the creator said:
theoretically it can be difficult, as it may require emulating the full CPU + CIA timer + IRQ environment, which SidDump doesn't really do. However, there may be a simple option of just breaking out when/if the init routine gets stuck into a loop, and executing the code pointed to the interrupt vector as each frame's play call. It may not work for all tunes though.
and:
check SIDDump 1.05 which was just released. It is not entirely foolproof (depends on how complicated code the player interrupt runs). Some multispeed tunes may work, others perhaps not.

True, I was just about to say the SID noise is teh shiz.
Curious to know more about the raspy noise that you are talking about, breakphase
Oh I guess I was just talking about the 1-bit noise from nes/atari/etc.. it has a little more grit I think because it has a low bit depth. And the drums from that are a little harder in my experience. I don't even know if I'm right about c64 being 4-bit, it just sounds too smooth for me a lot of times. Just a taste thing though.
$81,$80 = noise waveform. NATIVE WAVEFORM.
$82-$83,$86-$87 = a slight SYNC effect.
$88-$8f = reset noise
$90-$bf = not used (do not use: the noise dies)
$c0..$cf = rare extras(*)
$d0..$ef = not used (do not use: the noise dies)
$f0..$f7 = (*) rare extas: resets the internal pseudo random
generator...
$f8..$ff = : resets the internal pseudo random generator,
so the noise waveform play different, on some sids the
selected noise sounds more "metallic" depending on the
value and running SID cycles and other status.
Usage: first $f9, then $81
Wow I did not know about these, thanks!
Strange, it's the most versatile noise osc on 8-bit hardware. I remember when the 8-bit consoles came in it was such a disappointment how limited the Nintendo and Sega ones were to work on in comparisom.
I love everything else about the sid. It's closer to a "real synth" than everything else, but the noise might be a little "too good" for me... "double quotes!"

I was having trouble getting siddump to save to a text file until I found this page. I'll just leave these instructions here for my fellow n00bs...
1) Put the siddump program in a folder
2) Put the .sid file you want to analyze in the same folder
3) Open a command prompt and navigate to the folder with the cd command
4) Type something along these lines and hit enter: SIDDUMP sidfilename.sid -tX >textfilename.txt
Where X is the song's approximate length in seconds.
The folder will now also contain textfilename.txt. Open it in notepad. If you open it in wordpad the formatting will be incorrect.
Every row in the txt stands for a video frame. PAL is 50 frames per second, so if the song is PAL (probably), every 50 rows corresponds to 1 second in the song's play time. 60 for NTSC.
(Just saying.)

]]>One thing you could try is using the 'metal' noise waveforms. This guide has the full list:

]]>The bass tone is a sample loop. (like how chip modules do it) That 'noise slide' sound that sometimes comes in is probably a really tight instrument preset switching from noise to triangle(?) every couple of frames, would explain the thickness to it.
