There's no need to digitize each note from a synthesizer for the D/A: just sample one note from several octaves... for all the rest you simply change the playing frequency. This same method is used on the Amiga. And there's also a single-bit tone generator of any frequency you want. For more voices tho, yes you'd have to do software combination of the waveform before asking the hardware to play it. There was a cost issue also... and I'm glad they chose to include the 24-bit palette instead! An addition I'd like to have myself, is audio DMA which automatically loops. And altho there'll be I2C-controlled volume/bass/treble/fade external boards later on, it'd be nice if those were already built and included. Something I do like is that the output data doesn't need to share the video (Chip) RAM... it can come from anywhere in memory. Plus with the included input ports, sampling sounds is something almost everyone will be doing. cheers - kevin
