I'm going to try to make a quick thing a day during jan with my project.. some of those things might be music, some of them might just be pushing the software forward. Anyways, here is a little loop.
tdm for the drums and the first synth, sequencing the td-3 over midi.
I'm passing it through the m8, just for a little reverb & limiting.

another night of fighting usb ... I made some distinct progress, but still getting some kind of regular distortion. I think it has to do with mismatched buffer size or something.
anyways, I made a quick low effort tune, and looked briefly at how to unfuck my envelopes (I failed at unfucking them tonight, too tired)

Got new boards in the mail. The faceplate / back plates look great, I'm feeling semi confident about making a case for the whole unit.
I have a pretty spectacular fuckup in tbe big new chunk of hardware I added (power control system uses 1 ohm resistors instead of 100k ohm) but I was able to bodge everything into testability tonight.
At least one of the other fixes I made appears to work! Hopefully time tomorrow to check the other stuff.

spent 4 hours last night trying to chase down some subtle distortion that is affecting all my output. I didn't figure it out :(
my current best guess is that the DAC isn't getting clean power, and thats where the noise is coming from? I'm pretty sure that the data I'm passing it is clean (I am just passing it straight signed ints from a wav file). But there are so many moving parts here its hard to tell.

in more progressive news - i figured out why my batter powered unit is dying so quick, I'm using a voltage regulator that needs a 1v difference between its input and output. So when I pass it 4 v, it can only get 3 out. And the discharge curve for lipos is such that they only stay up above 4v for a short part of their discharge.
easy to fix, I found an alternate component to drop in already.

getting better at fixing things that are broken - tonight, bodged in https://www.diodes.com/assets/Datasheets/APX803S.pdf for the screen reset, and everything went to shit, because I cut an important power trace. I managed to bodge everything back into working order, and yep! it appears that the reset chip works. Huzzah.

tomorrow night: I resolve to not fight usb ... at all. maybe just do a quick tune?
