Bad definition for frequency multiplier MUL

[jpcima]

The info tip of MUL refers to the OPL3 sample rate in its formula. This can't be right.
Should this be instead 53267?

I think, I need to check, this formula was copied from OPL3 documentation, for OPN2 it would be different, but yeah, 53267

[freq-mod]

Rate scale level description also seems misleading, rather than attenuating output towards higher pitches it shortens the envelope (entirely) - attack rates become faster, decays are shortened as well.

Think of it like it's OPL3's KSR.

Fixed on a quick hand!
