This time, I am doing a double POKEY tune. My code is correct, but when I modify it for SAP-B as with earlier examples, it crashes. Anybody have ideas?
Just an update ... I am in the middle of writing out a documentation of what I have named $4x/$Cx mode. The setup is:
AUDCTL=$40 (1.79 mhz on top of 64 khz clock) SKCTL=$8B (two-tone mode)
Set distortion $4x in first channel Silence second channel or play $Cx distortion.
There are at least 6 or 7 note tables to be had in this mode. Most produce distorted guitars.
In this setting, you have to contend with frequencies in the mod 3 and mod 5 ranges (like C distortion) and also mod 15 and mod 31.
If you store a mod 15 value in first channel and you put standard C distortion frequency in second channel, you get a fuzzy C distortion. The higher the modulation in channel 1, the fuzzier it sounds.
If you store mod 5 (not 15) in 1, you put frequencies close to C distortion in 2, and it makes distorted guitars.
