v0.0.7

Multidrive calibrated against recordings of the original's factory presets: decoded knob
positions played on the recordings' notes, and the engine's constants fitted to them. At full the
original is grittier than SubForce was: the second stage (after the ladder) now clips harder (its
gain at full 2.0, was 1.5) and the drive into the ladder goes to 9×, was 8×. About half of what the
fit asked for, as only two sounds settled it. Below about a third of the knob the change is slight.
The factory presets are re-levelled (−16 LUFS, most within ±0.3 dB).

For comparisons like it, tools/demos renders preset files from anywhere (--files), a preset on a
note list (--notes) and jobs on stdin (--serve); build/demos_tune makes the engine's tuning
constants settable for fits (see Building).
