The Queen of Industrial Grunge Got an Upgrade — Sophisticated Dirt!

#Elmyra2 v2.4 — What’s New and Improved Sound Engine

Higher sample rate and improved wavetable resolution → noticeably cleaner top end. New wavetables added. Overall mix saturation refined, with “soft” (122) now default. Knob value stability and tuning precision improved.

Filters
New comb filter (codes 3321/3322). RESO = damping, CUTOFF = delay time, with optional pitch tracking. Ladder filter reworked — now true multimode (LP/BP/HP) with higher quality. Ladder LP (331) is the new default filter. State-variable filter retains LP/BP/HP modes (341–343) but with improved gain staging, resonance, and cutoff ranges.

Delay & Reverb
Delay fully re-implemented → cleaner feedback, no lock-ups.
Added proper reverb engine controllable with delay knobs.
Code 441 = delay (default), 442 = new reverb, 4411 = legacy lo-fi reverb.
TIME = decay, FDBK = color, MIX = blend.
Dry/wet crossfade curve improved for smoother transitions.

Modulation
New MODP: oscillator hard-sync (orange LED, position 5).
MOD controls the synced oscillator pitch.
LFO1 knob-motion recording (code 2413) — record live movement of LFO rate. Sequencer output to LFO1 possible (243v).
Per-voice sequencer clock divider (11sv).
Digitally controlled envelopes in multiple short modes (221v → very short … 224v → disable). Detune MODP range expanded.

Scales & Chromatic Mode
New musical scales for chromatic mode: major, minor, major pentatonic, minor pentatonic (CHRM + 11–14). Scale selection now unified under the CHRM button. Knob-to-pitch mapping in chromatic mode is now linear and exact.

User Interface & Workflow

LED feedback overhaul — REC and PLAY flash to confirm code entry, sequence record, mute, and drone states. Quick mute/unmute voice (MODP + PG long press). Quick octave switch (MODP + double-tap PG).
Pink MODP LED at startup identifies firmware 2.4.
Touchpad LEDs more reliable during operation.
Drone and mute response feels snappier.

Under-the-hood Fixes
State-variable filter crash fixed (previously triggered by fast cutoff modulation).
Improved detune, filter, and delay behaviors under modulation load.
Sequencer timing more consistent with internal clock.
