v1.34.0
Fixed
- Trail and feedback effects measure trail length in seconds now, not frames, so the same
preset looks the same on a 30 Hz laptop and a 240 Hz desktop — at a decay of 0.82 the image
surviving one second ran from 2.6e-3 at 30 fps to 2.1e-21 at 240. Nothing changes at 60 fps;
above it, feedback backgrounds that accumulate particles settle brighter than they used to,
and below 30 fps trails run a little long instead of flashing dark on a stutter. - The drop event fires on drops now — it had gone off once in 141 reference drops across
374 tracks, because it demanded 4 seconds of unbroken build-up before it would even watch
for one. On nine hand-labelled EDM tracks it now catches 7 of 23 drops at three wrong cues
for every right one; it still fires on build-ups and breaks. The audio panel's Drop sliders
trade sensitivity against false cues. - The drop jump window now lasts the 1.5 seconds it always claimed. It was sized against
the analysis rate but filled at a tenth of it, so the setting was off by nearly ten times —
and by different amounts at different sample rates (12.9 s at 44.1 kHz, 14.1 s at 48 kHz).
Added
- Two new Drop sliders in the audio panel: "Arm hold" keeps the drop armed through a cut
before the drop, for material where the build-up drops out entirely first (off by default);
"Jump window" sets how far back the loudness-jump baseline looks.
