Ressup-EQ 1.26.4

• Fixed the broken Windows x64 VST3 that crashed the DAW when opening the editor.

Ressup-EQ 1.26.3 — Natural LU Match automation fix

Fixed LU Match automation in Natural mode so changes respect their sample offsets and produce consistent results across buffer sizes.

Ressup-EQ 1.26.2 — Adaptive Res Sup and curve response

Ressup-EQ 1.26.2 expands Res Sup capacity and makes its response follow the selected curve.

• Adaptive control points per band: 512 with 1 active Res Sup band, 384 with 2–3, 256 with 4–6, 128 with 7–12 and 64 with 13–24. Density selects how many qualifying resonances are treated within that capacity.
• Curve selection stays available with Res Sup enabled. The selected EQ shape also defines the detector sensitivity.
• All Pass now has uniform sensitivity across the full frequency range. Bell, shelves, cuts, Notch, Band Pass and tilts each use their appropriate response, including cut slopes and tilt direction.
• Switching curves immediately refreshes the detector candidates.

Ressup-EQ 1.26.0 — Default settings and presets

Ressup-EQ 1.26.0 adds reusable default settings and a new preset browser.

• Save as default and Reset default in Settings for analyzer resolution, minimum level, speed and Curve suggestion.
• New instances start with an empty EQ and a neutral signal path. Existing projects restore their saved state.
• Compact Instances icon in the header.
• Folder icon before Pre with 20 factory presets, user presets, Open, Save as and Show preset folder.
• Portable .rseq presets with precise values; legacy .rsp presets remain readable.

Ressup-EQ 1.25.0 — 64 resonances per band

Res Sup now processes up to 64 simultaneous resonances per band. Density selects the peak budget from 1 to 64; around 54% allows 35 peaks. The actual number follows the detected signal and Threshold, while Amount and Q control the correction.

• Dense, closely spaced peaks remain eligible at fine FFT resolution.
• Processing skips inactive filters and reuses Range-limiter calculations to reduce CPU work.
• Local, Linear phase and cross-instance response curves include voices beyond the eighth.
• Older saved projects and presets retain their previous one-to-eight peak budgets. Existing Density automation percentages must be rescaled by 7/63 to retain their previous budgets. Parameter IDs and positions are preserved.

Higher Density can increase CPU use when many resonances are active. Dense multi-band sessions need more processing headroom.

Validation

• macOS: VST3 SDK validator 47/47; five selected capacity, GUI, VST3 quality, AU bridge and DSP suites passed. The exact 1.25.0 AU bundle passed a direct stereo 48 kHz render smoke test with 646 parameters. Builds are ad-hoc signed, without Apple notarization.
• Linux: five selected capacity, CLAP, resonance, comparison and sidechain suites passed. The exact stripped package binary passed 38 audio checks, 13 GUI checks and the CLAP validator (35 passed, 9 skipped). REAPER 7.82 loaded that file, opened its custom editor and rendered the expected +9 dB at 48 kHz stereo. Tests used Ubuntu 22.04 x86-64 userspace under Rosetta in a Linux VM on the development Mac.
• Windows: cross-built x64 binary; architecture, version, plug-in exports and runtime dependencies checked. Native Windows DAW testing remains pending.

Ressup-EQ 1.24.0 — Persistent instance chains

Instance names and inter-instance chains now survive project reloads. Each band can use the DAW sidechain input or another named Ressup-EQ instance to trigger Dynamics and Res Sup.

• The MAIN / named-instance selector is beside Instances; the duplicate controls above the parameter panel have been removed.
• Each band's Details drawer offers External SC, MAIN and the other live instances.
• Stereo Post audio is exchanged between instances, including across host processes. Mono VST3 external sidechain routing is fixed.
• Names, identities, comparison selections and per-band instance sources are saved. Chains reconnect when source instances load later or in a different order.

Projects saved by earlier versions do not contain this instance metadata. Assign names and sources once, then save again with 1.24.0. Existing parameters and automation remain compatible.

Ressup-EQ 1.23.0 — Res Sup Density

Ressup-EQ 1.23.0 adds an independent Density knob to Res Sup.

• Density 0–100%: select the strongest qualifying resonance through up to eight simultaneous peaks, with gradual entry of secondary peaks.
• The former signed intensity slider is now labeled Res Sup Amount in the editor. Its host automation name, ID and stored values are preserved.
• Each band saves its own Density. Existing projects open at 100% Density, retaining their previous sound.
• Threshold selects eligible peaks, Res Sup Q controls their width, and Amount controls direction and strength.

Ressup-EQ 1.22.1

Ressup-EQ 1.22.1

• Scroll anywhere to adjust Q for the selected band, including over controls or another node. Shift keeps fine adjustment. Scrolling retains the current band and main/reference target.
• Click empty spectrum space to hide the parameter panel. Clicking a band node selects it and restores its controls.

Four binary packages only: macOS Apple Silicon VST3 and AU (macOS 14+), Windows x64 VST3 (Windows 10/11), and Linux x86-64 CLAP (glibc 2.35+, X11/XWayland), plus SHA256SUMS.txt.

Packages contain compiled plug-ins and their licenses.

The README describes the current controls and installation folders. Existing processing and saved settings remain compatible.

Validation covers the Mac editor and VST3 bridge, VST3 SDK validator and Apple's AU validator; the final Linux CLAP's audio and editor integration, CLAP validator and REAPER load/render check under Rosetta in Ubuntu 22.04 x86-64 userspace. DSP build inputs are unchanged from the fully tested 1.22.0 release. Windows is cross-built with PE architecture, version, exports and runtime-dependency checks; a native Windows DAW test remains pending. Mac binaries are ad-hoc signed and are not notarized.

Ressup-EQ 1.22.0

Ressup-EQ brings parametric EQ, Dynamics and adaptive resonance suppression into one 24-band workspace.

• Continuous per-band L/R and Mid/Side processing balance below Gain; full processing on both at the centre.
• Optional Curve suggetion chooses the initial high-pass, low shelf, bell, high shelf or low-pass curve from the insertion frequency.
• Compact right-click curve menu with icons for all ten shapes. Clean numbered nodes in the spectrum.
• Wider analyzer with logarithmic subdivisions and an independent right-hand dBFS scale.
• One combined response, live instance comparison and reference editing, three phase modes, configurable spectrum, Freeze peak picking and Loudness Match.

The README is a complete guide to the current features, with a fresh interface image. Existing project settings and channel automation remain loadable.

Validation

Mac: nine automated suites, the VST3 SDK validator and Apple’s Audio Unit validator. Linux: audio and editor integration, CLAP validation, and an exact-packaged-binary REAPER load/render check in Ubuntu 22.04 x86-64 userspace under Rosetta. Windows: cross-build plus PE architecture, version, exports and runtime-dependency checks; a native Windows DAW run remains pending.

The Linux GUI screenshot required a retry after an X11 BadMatch under Rosetta; the separate final-file run passed all 13 editor checks. This is recorded in the Linux verification manifest.

Mac binaries are ad-hoc signed and are not notarized. At 48 kHz, Linear reports 8,704 samples at Detail 0 and 17,408 at Detail 1–5; Natural reports 49 and 561 respectively. The host receives the actual latency. For heavy 24-band Linear work at maximum Detail, start with a buffer of 128 samples or more. Very narrow Linear filters have finite resolution, reflected by their displayed response.

Ressup-EQ 1.21.0

Changes in 1.21.0

• Sample-accurate VST3 automation, with smooth trim, Mix, Bypass and band changes.
• Higher-resolution symmetric Linear FIR and curves that display its actual finite response.
• Symmetric Natural oversampling and the original, latency-aligned dry signal at Mix 0%.
• Correct output loudness metering through Bypass and guarded LU MATCH transient compensation.
• Separate Res Sup corrections for close, resolved peaks, with fast transient tracking retained.
• Improved instance-control exchange under brief contention.

Saved parameter IDs and state format remain compatible. Corrected Linear and Natural responses can sound different from earlier releases; their host-reported latencies have changed.

Downloads

• macOS Apple Silicon: VST3 and Audio Unit, macOS 14 or later.
• Windows x64: VST3, Windows 10/11.
• Linux x86-64: CLAP with the custom editor, glibc 2.35+ and X11/XWayland.

Exactly four binary packages plus SHA256SUMS.txt. Packages contain compiled plug-ins and accompanying licenses, with installation information and verification metadata where applicable.

Latency and heavy configurations

At 48 kHz, Linear reports 8,704 samples at Detail 0 and 17,408 at Detail 1–5. Natural reports 49 samples at Detail 0 and 561 at Detail 1–5. Delay compensation uses the latency reported to the host.

Use 128 samples or more for heavy 24-band Linear configurations at maximum Detail. One 64-sample macOS stress case recorded a missed deadline; all tested 128-sample cases completed without one. Very narrow Linear filters remain finite-FIR approximations and their displayed curves reflect that response.

Validation

macOS: all nine automated test suites, the VST3 SDK validator, Apple's Audio Unit validator and audio-quality sanitizer tests. The macOS packages match the verified 1.21.0 build installed on the development Mac.

Linux: audio and editor integration tests, the CLAP validator and an exact-packaged-binary REAPER load/render check in an isolated Ubuntu 22.04 x86-64 userspace running under Rosetta on this Mac. Windows x64: cross-build, PE architecture, version, exports and runtime-dependency checks; a native Windows DAW run was not performed.

Linux GUI verification passed all 13 checks on an 8192×4608 virtual desktop. An initial screenshot attempt on a smaller Xvfb desktop failed with X11 BadMatch under Rosetta; this VM test limitation is recorded in the Linux verification manifest.

macOS binaries are ad-hoc signed and are not notarized.
