EON ReaKit Bundle - Changelog

v1.1.0

New Plugin

• ExpressBus (ssl bus.jsfx) - SSL-style bus compressor with ReaKit Grey Panel GUI, SSL 4000E knobs, VU meter, sidechain input, feedback/feedforward modes, peak/RMS detection, hard/soft knee, manual/auto makeup, and ReaKit link group support.

Bundle-Wide Changes

• Import path refactor: All plugins now use relative import paths (e.g., import ../ReaKit/utils_kbsg.jsfx-inc) instead of bare filenames, fixing resolution from the Eon_JSFX/ subdirectory.
• Embedded detection fix: All plugins changed is_embedded = (gfx_ext_flags != 0) to is_embedded = (gfx_ext_flags & 1) using proper bitmask.
• Mouse variable rename: Standardized to prev_LMB/prev_RMB across all plugins.
• Keyboard/focus handling: Added gfx_getchar() call in @gfx to multiple plugins for keyboard and modifier-key detection.

Shared Library: meters_kbsg.jsfx-inc

• Feature flag system: New opt-in flags (mtr_en_vu, mtr_en_rms, mtr_en_lufs, mtr_en_phase, mtr_en_gonio, mtr_en_wave, mtr_en_spectrum) so plugins only run the meter subsystems they need.
• Peak metering moved to linear domain: Peak envelope and hold tracked as linear amplitude; log10() conversion deferred to new mtr_update_db() function called from @gfx, removing per-sample log10() from the audio thread.
• Linear-domain hold decay: Peak hold decay uses multiplicative decay in linear domain instead of subtractive decay in dB domain.
• All expensive subsystems gated: VU spring-damper, true RMS, K-weighted LUFS, phase correlation, goniometer, waveform, and spectrum are all wrapped in their mtr_en_* conditionals.

Per-Plugin Changes

1175_ReaKit.jsfx (1175 Compressor) - Added mtr_en_vu = 1 flag to enable VU needle metering.

3BandEQ_ReaKit.jsfx - Added 5ms one-pole gain smoothing for Low, Mid, High, and Output volumes (prevents zipper noise on parameter changes). - Added snap_params pattern: on first sample after load, smoothers snap to target values instantly (avoids ramp-from-zero glitch on project reload).

4BandEQ_ReaKit.jsfx - Added retina guard: ret = max(1, gfx_ext_retina) to prevent division by zero on non-retina displays.

ChannelTool_ReaKit.jsfx - Added cDenorm constant for denormal prevention. - Added mtr_en_vu = 1 flag. - Added snap_params pattern for all gain/pan/balance smoothers. - Denormal protection added to DC blocker filter inputs. - Denormal protection added to all HPF and LPF biquad filter inputs (8 instances). - Meter processing now gated by play-state.

Compressor_ReaKit.jsfx (Prism Comp) - Added cDenorm constant. - Added snap_params pattern with smoother snap on project load. - Division-by-zero fix: Attack/release calculation changed from max(..., 0) to max(..., 1) preventing divide-by-zero at 0ms. - Denormal protection on sidechain HPF/LPF biquad inputs (4 instances). - Division-by-zero fix: All gain reduction / rmsL and / rmsR divisions now use / max(rms, 0.000001) (6 instances). - Saturation drive/inv_drive precomputed at block rate instead of per-sample. - RMS sqrt skipped when blend_t is 0 (pure peak mode). - GUI refactored: extracted set_mode_color() and mode_knob_draw() helpers, replacing 7 duplicated knob-drawing switch blocks.

DDC_ReaKit.jsfx - Added cDenorm constant and snap_params pattern. - Denormal protection on sidechain HPF/LPF inputs, DC blocker, and saturation paths. - Saturation drive/inv_drive precomputed at block rate.

DeEsser_ReaKit.jsfx - Added cDenorm constant. - Denormal protection on all LR2 crossover biquad filters (12 biquad computations across live and delayed signal paths).

Delay_ReaKit.jsfx - Added 5ms one-pole parameter smoothing on feedback, dry, wet, width, and chorus mix (eliminates zipper noise during automation). - Added cDenorm constant and snap_params pattern. - Denormal protection on HP and LP filter biquad inputs (4 instances).

DirtSqueeze_ReaKit.jsfx - Added cDenorm constant. - Added DC blocker (~5Hz HP) after waveshaper output to remove DC offset from asymmetric waveshaping. - Added snap_params pattern with makeup gain smoothing. - Added retina guard.

GainKit_ReaKit.jsfx - Added cDenorm constant and mtr_en_vu = 1 flag. - Added snap_params pattern for output gain, L trim, and R trim smoothers. - Denormal protection on DC blocker and all HPF/LPF biquad inputs (8 instances). - Meter processing gated by play-state.

Gate_ReaKit.jsfx - Added cDenorm constant. - Added snap_params pattern. - Denormal protection on sidechain HP/LP biquad inputs (4 instances). - Peak meter decay now uses sample-rate-corrected constant instead of hardcoded 0.9995. - Lookahead buffer: modulo operations replaced with bitwise AND for power-of-2 buffer sizes.

MIDINoteRepeater_ReaKit.jsfx - All knob-change callbacks now call atomic_set(dsp_dirty, 1) to properly flag DSP recalculation (7 handlers). - Color legend labels dynamically centered over keyboard key groups using gfx_measurestr().

Reelism_ReaKit_v15.jsfx - Added cDenorm constant and snap_params pattern for drive/tape/denoiser/output. - Denormal protection on head bump filter calculations.

Reverb_ReaKit.jsfx - Added snap_params pattern with recalc_dsp() on first block. - ISN tap offset computation moved from per-sample to block-rate. - Removed per-sample PDC reset.

Saturation_ReaKit.jsfx - Meter processing gated by play-state.

Spice.jsfx - Added gfx_getchar() for keyboard handling.

StereoWidth_ReaKit.jsfx - Added cDenorm constant and snap_params pattern. - Denormal protection on DC blocker feedback paths. - Correlation metering and meters gated by play-state.

The_Best_DeEsser_GUI.jsfx (DeBess) - Memory layout fix: lookR buffer start changed from hardcoded 6000 to lookL + buf_size, fixing buffer overlap that overwrote GUI knob memory. - Buffer size fix: Changed from 5000 to 8192 with bitwise mask. - Added snap_params pattern. - Precomputed scale_8192 and scale_half constants. - Sidechain HP filter fix: hp_coeff now uses sample-rate-corrected formula instead of raw value tuned only for 44.1kHz. - Sharpness values precomputed once per block instead of per sample.
