I think the TED chip has 8 bit resolution on voice #1 and 10 bit resolution on voice #2, the one that is shared between square wave and white noise. Since I have made TED music once, I should remember it better than I do. I found some kind of note table here: http://www.dtech.lv/files_pgm/commodore_plus4_pal.txt For that matter, the Atari POKEY chip usually is rather out of tune as well, for those songs utilizing all four 8-bit voices. The POKEY however can be reconfigured as one 16-bit + two 8-bit voices or even two 16-bit voices for much improved accuracy at the cost of fewer voices. I haven't studied how good accuracy e.g. the AY-3-8910 or SN76489 chips provide, but surely every single bit of added control improves the sound. Not that it really matters in this discussion, other than excusing that the VIC-I might not sound that much worse than most of its contemporaries. Comparing with the SID chip is like comparing a $15,000 car to a $100,000 car. Best regards -- Anders Carlsson Message was sent through the cbm-hackers mailing listReceived on 2011-12-29 13:00:23
