Tracker actually makes sense

lemonade (04:03:27)
Oh nice, I can help testing

Also why i was so excited about the music quality of 1541u2's output, i should make my tracker/DAAW to support this u2's audio, then it is truly a stereo DAW environment. On c64!

The same at positions $3f, $40 -> $41 and then $bf, $c0 -> c1 should fix it up pretty much, the rest of it cannot be even heard ($20, 60, a0, e0) and i'm quite sure this will just work.

Agemixer (03:46:42)
Yes, a lookup table of .. $7e, 7f, 82, 83 .. or a skip around like that, cant remember exactly. So it will give 250 amplitude stages instead of 256

lemonade (03:45:56)
So, ok, i see you already have fix planned

lemonade (03:44:32)
Ah .. going to fix it somehow?

Agemixer (03:44:27)
So for example a simple (full scale) saw waveform the osc ramp on output is not linear but for silent samples it can be compensated with an extra lookup table for each amplitude stage to linearize it. It is most noteable at "zero" sample value, $7f <-> $80

Agemixer (03:38:46)
Now i know what is the culprit for the noisy output of Breadamp and real SID: It doesn't compensate the PCM values for the SID, it introduces a little NOTCH exactly at zero value sample.

Yes, school morning for kids
