hey @ross, there's a typo in rossabaker.com/series/the-rust-prog… (langauge) - it also appears next to the publish date on the articles themselves e.g. rossabaker.com/blog/rust-book-ch07

ok this is so cool. this LED manufacturer designed maybe the coolest demo brochure possible for their COB LEDs, its a ringed binder where each of the pages is a PCB that you plug in and can control via touch to toggle which strips are on 🤯 #electronics

I guess I only managed to hit the "self-taught" jackpot once. Never underestimate how hard it is to actually learn a skill on your own...

all this time spent learning in Syntorial and I still have ZERO creativity when it comes to creating sounds.

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 24/04/2026

I spent 30 minutes with the synths. I think I'm starting to realize I'll never be remotely good at this. Not until I successfully sacrifice all my free time to INTENTIONALLY learning the missing pieces. Just playing the keys doesn't count (and it gets old real quick)... #jkmakesnomusic

I think my problem is that I try to do everything at once (composition, sound design), and I'm not great at either of those things so I immediately get hit with disappointment. Need to go with baby steps and focus on one thing at a time

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 15/03/2026

The #jkmakesmusic project has been on hold for about 2 weeks now (as I'm sure all of you noticed). I just set up my synths to just play something for a change, and it turns out all of my "creative ideas" still evaporate the moment I think of pressing a key 😞 it's making me sad, so I'm going to […]

March 2 - #jkmakesmusic words can't describe this feeling

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 02/03/2026

March 1 - #jkmakesmusic Final Challenge 3 DRAGGED me. 3/3, 2/3 (used too much cutoff for no reason, not that there was any audible difference), 3/3. 3 stars overall, but at what cost... That's enough for today, I want to actually get some sleep.

100

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 28/02/2026

got the last one slightly off (2 stars in one patch don't take away the ability to get 3 stars from the three patch section), but I honestly couldn't hear the difference so I'll take that as a W. 6 patches done, 6 more to go, and then... well, I don't see any […] [Original post on mstdn.party]

Missed a day. I drove us back the whole way from Slovakia so I think it's a decent excuse. Feb 28 - #jkmakesmusic - and today is the day we start the Final Challenges!

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 26/02/2026

well, yeah, it's very different! - I used two wide pulse waves, original was a square doubled with a triangle - filter decay/release were longer than I thought, almost 2s whereas I used 0.6s. Could've been a different slope - amp release was also longer, 1.8s vs […] [Original post on mstdn.party]

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 26/02/2026

nah, it's not LPF. But I used the wrong type of BPF before, this one is closer. Still not quite there, but I think the difference is in how Vital's resonance works.

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 26/02/2026

current status, but I don't buy it. Maybe it's LPF after all

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 25/02/2026

next one is Lead Spiders. PB range is 4, wave sounds like a square (or is it FM?). I think it's two oscillators (one 19 semis above) AND a sub. Not hearing a lot of low end so maybe BPF, with an envelope (quick attack, then about 0.5s decay/release). Or it could be FM and what I said about the […]

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 25/02/2026

alright so - Primer used two saws manually to do the unison, I just used the effect, that's okay. LPF with some envelope and exactly 1s attack, 1.9s release (I used 1.8). 15 PB range. Square sub. Nailed it!

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 25/02/2026

Feb 25, #jkmakesmusic I spent roughly 15 minutes on this? Probably got something wrong, but it sounds close enough

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 24/02/2026

Bass Heavy - 15 semitones of PB range, sub present, likely 2-voice unison, could be a thin pulse wave. About 1s filter envelope attack, about 2s amp release (amp), filter is probably LPF. For tomorrow!

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 24/02/2026

turns out it was saws anyway. 19 semitones is right, interestingly the filter env release was very long, which I do hear now but I didn't hear before... velocity target was indeed filter env amount, there was reverb as well, and 2-voice unison. My version had 4 […] [Original post on mstdn.party]

and here's a comparison across other octaves (reference first, my version second). Time to reveal the cards...

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 24/02/2026

Feb 24 #jkmakesmusic ended up moving to a thin pulse wave, everything else stayed the same I think. The biggest difference seems to be caused by the reverb differences, but we'll see if there was anything else.

Feb 23 New day, new patch - Pluck Plucky. 6-voice polyphony, two oscillators a fifth apart (maybe an octave or two more, I'm guessingi it's 19 semitones total). Plucky ADSR on the amp and LPF filter, I think the velocity simply controls the filter position, but it might as well be the filter […]

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 22/02/2026

ok, apparently there wasn't any filter at all (I suspected this but it didn't play well with the other parameters). Good 'nuff. (delayed post)

000

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 22/02/2026

noticed just now that there's an additional envelope, it's adding an attack transient on the FM amount it seems. Here's my result.

yeah I missed Saturday - I was beat. Feb 22 - #jkmakesmusic That OYO - we've got delay, a subtle phaser, and two oscillators (one seems to be a sub, maybe a triangle one). I suspect main osc is FM (or I'm overthinking it and it's just a wave). Velocity is mapped to volume. Filter is a LPF […]

ah - for computer keyboard users, you just get keyboard shortcuts to increase or decrease velocity.

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 20/02/2026

I was wayyyy off. I got the filter type right, and the detune amount, but it was still a saw wave, and I didn't turn on the phase reset (which corresponds to Primer's Start checkbox). stil... the self-oscillation sounds completely different, even when I use saws […] [Original post on mstdn.party]

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 20/02/2026

still not great, but also not terrible? could it be a pulse wave with HPF? I'm gonna check.

I don't know, man. Grasping at straws here, I tried the MM2 to see if it was any Vital weirdness, but I can't find it still. Even tried a pulse wave.

Feb 18 random note, I don't know how I can get a negative ramp saw wave (top) once I switch the oscillator to something else. It's nowhere to be seen in the other wavetables, I see a saw in Basic Shapes but that's a positive ramp. #jkmakesmusic

Jakub Kozłowski @kubukoz.mstdn.party.ap.brid.gy · 17/02/2026

Next up (for tomorrow): Lead Self Osc. Well, clearly it's gonna self-oscillate, and since the pitch follows the main note I'm gonna assume it has a LOT of key tracking. There's delay, pretty fast 2-voice unison, a very quick (sub-half-second?) amp release, and I have no clue what the filter is […]

Approach one. Using relatively thin square waves and quite a lot of resonance on the BPF.
