] By the way, did you know that the formula for SCC frequencies is like this:
]
] sccfreq = (msxfreq / 32) / (sccfnum + 1), where:
] sccfreq is the played frequency (in Hertz)
] msxfreq is the MSX clock frequency (3579545 Hz)
] sccfnum is the value you poke in the SCC memory area
]
] None of the info I had (including the info I put on my web page) mentioned
] the "+1"...
Yes.
I found this out when I wrote SME3, back in 1991. First I assumed it would be
(msxfreq/32)/sccfnum, just like on the PSG. But it was detuned a little bit
from the PSG. So I tried both +1 and -1 to find the proper formula and the +1
worked fine.
Kind regards,
