@BKP: thanks for the feedback and the kind words! I noticed in Castle Dance you are writing registers 0-13 in a loop at once, while in Cross Scroll Demo there appears to be a different approach. One awkward thing is that in Castle Dance values (> $0F) are written into the coarse (high) frequency register which are higher order than the actally usable range.
@gerliczer: thanks for looking this up for me. Ironically, the TED has something similar where the lowest tone is actually $3FF as the oscillator counter's increment happens before the compare. I am not saying this is the case here as more sources suggest indeed that value 0 is in fact 1 but no word about 1 being 2 for example
