Hyperfocus DSP — devlogEngineering notes from Hyperfocus DSP.https://hyperfocusdsp.com/You wrote, I fixed it: Niner v0.7.1 (and v0.7.2 a few hours later)https://hyperfocusdsp.com/devlog/2026-05-01-you-wrote-i-fixed/https://hyperfocusdsp.com/devlog/2026-05-01-you-wrote-i-fixed/Seven UI bullets a tester sent the morning v0.7.0 shipped. Seven UI bullets that landed in v0.7.1 a week later. Plus a status-flash fix and a factory-bank refactor that snuck out as v0.7.2 the same afternoon.Fri, 01 May 2026 00:00:00 GMTI renamed my plugin two weeks after launchhttps://hyperfocusdsp.com/devlog/2026-04-26-renamed-my-plugin/https://hyperfocusdsp.com/devlog/2026-04-26-renamed-my-plugin/Shipped a kick synth called Slammer. Found out two weeks later that another company already shipped a plugin called Slammer. Renamed to Niner, kept the DSP, broke a few things on purpose, here's what migrated cleanly.Sun, 26 Apr 2026 00:00:00 GMTThe knob I removed from my pluginhttps://hyperfocusdsp.com/devlog/2026-04-21-the-knob-i-removed/https://hyperfocusdsp.com/devlog/2026-04-21-the-knob-i-removed/Niner shipped with a VEL knob that did nothing in every context a solo producer uses. I removed it instead of justifying it.Tue, 21 Apr 2026 00:00:00 GMTWhy I stopped trusting `tanh` for kick-drum distortionhttps://hyperfocusdsp.com/devlog/2026-04-21-why-i-stopped-trusting-tanh/https://hyperfocusdsp.com/devlog/2026-04-21-why-i-stopped-trusting-tanh/Symmetric tanh is great on steady-state signals and quietly wrong on a kick drum. Here's what tanh distortion does to a transient, and what Niner ships instead.Tue, 21 Apr 2026 00:00:00 GMTThree things I got wrong about diode ladder self-oscillationhttps://hyperfocusdsp.com/devlog/2026-04-18-diode-ladder-self-oscillation/https://hyperfocusdsp.com/devlog/2026-04-18-diode-ladder-self-oscillation/I broke my diode ladder filter three ways getting self-oscillation right: symmetric diodes, lazy feedback, and a solver that exploded above 15 kHz.Sat, 18 Apr 2026 00:00:00 GMTBouncing a plugin to disk without touching the audio threadhttps://hyperfocusdsp.com/devlog/2026-04-18-niner-bounce-button/https://hyperfocusdsp.com/devlog/2026-04-18-niner-bounce-button/Niner's BOUNCE button renders a one-shot to WAV while live audio keeps flowing. Here's how I kept it deterministic, off the audio thread, and bit-identical.Sat, 18 Apr 2026 00:00:00 GMTHello from a fresh repohttps://hyperfocusdsp.com/devlog/2026-04-17-hello/https://hyperfocusdsp.com/devlog/2026-04-17-hello/What this blog is for, what gets written here, and what doesn't.Fri, 17 Apr 2026 00:00:00 GMT
