| 01:58 | | * McMartin crackles with eldritch power |
| 01:59 | <&McMartin> | This extremely bad idea is looking suspiciously like it's going to actually work. The prototype is far more functional than I had dared to hope. |
| 02:02 | <&[R]> | Oh/ |
| 02:05 | <&McMartin> | The retro system I'm coding for has a less-than-1-MHz CPU and its sound hardware is just a straight DAC that you write 6-bit values to |
| 02:05 | <&McMartin> | So to do a sound you have to write values to it in a cycle-counted loop, more or less. |
| 02:06 | <&McMartin> | That's not terrible on its own but normally you are either counting out the limbs of a square-wave, or you're busting out a digital clip to a multi-kilohertz beat |
| 02:07 | <&McMartin> | I've managed to get 3-channel polyphony with instruments defined by 32-byte wavetable definitions, and it still has enough time left over to check the keyboard and process a music score so you get actual songs out. |
| 02:08 | <&McMartin> | The bitrate is a little bit shaky at the moment so the move from prototype to production will involve smoothing out the timing across what branches exist and then determining if that's even a good idea given the tradeoffs, and then adapting some of my other tooling so that it can produce music scores consumable by the system |
| 02:10 | <&McMartin> | And now I have about a month to get all this working and written up before I run out of stalling topics on the blog >_> |
| 02:10 | <&McMartin> | The digital-clip-playback material went up yesterday, though: https://bumbershootsoft.wordpress.com/2024/03/02/the-dragon-roars/ |

| 07:42 | <&McMartin> | ... oh my goodness |
| 07:44 | <&McMartin> | And now that I've done the tuning on the core routine, I've somehow _accidentally_ gotten as close as it is possible to get to have the frequency code for Middle C be 0x1000. |
| 07:44 | <&McMartin> | Nobody will ever believe me when I say this was by chance. <_< |
