Release Notes

Cambridge Bus Compressor

Three-band bus compression with two independent lanes and guided GR Intelligence v1.0.0

View details

Initial release highlights - Calibrated bus-compressor model with 20 factory presets. - Stereo Linked, independent L/R, and M/S routing. - Stereo Linked uses lane A as the single runtime authority for compressor controls and crossover on both channels; stored lane B settings resume when routing is unlinked. - Independent lane/band control with asymmetric multiband layouts. - Processor-owned Auto GR with editor-open/headless equivalence. - Auto GR disengage commits both effective Threshold and level-restoring Gain, preserving the manual handoff without a level jump. - While Auto GR is active, the GAIN control follows the effective live makeup offset without writing host automation or changing the stored manual value. - Manual GAIN drag, typed-value, and default gestures during Auto GR target the displayed effective Gain without double-counting the live makeup offset. - Visible Mode, Detector Mode, external sidechain, sidechain-listen, and routing-aware Listen controls, synchronized with host automation and state. - Per-channel metering, bypass/state synchronization, and deterministic recall. - Fixed native-rate 1x processing with zero oversampling latency. - VST3 and CLAP formats. - Free product: no licence, activation, trial, demo interruption, or network use.

Cambridge Channel Strip

Filters, four-band EQ, compressor and gate — with two independent lanes v1.0.0

View details

Cambridge Channel Strip is a console-style channel strip in a single plugin: input conditioning and phase, high- and low-pass filters, a four-band EQ, a compressor and a gate/expander sharing one dynamics section, a global sidechain, and output trim. Work in linked Stereo, or split into two independent lanes with full Left/Right and Mid/Side routing. This is the first public release. It runs in demo mode until activated with a licence key: every control is active and there is no time limit, but a 2-second silence interruption occurs every 60 seconds and is printed into renders and exports.

• The EQ graph now uses a symmetric gain axis: +/-24 dB with 0 dB at the centre, signed labels, and an emphasised unity line. Previously the axis was labelled as gain reduction (0 down to -12), which did not describe the curve being drawn - the centre of the plot was 0 dB but was labelled -6.
• Removed the "LIVE CORRECTION" overlay. That trace plots dynamic gain reduction; this is a static EQ, so it always reported zero and drew a flat line pinned to the top of the graph under a label for a feature the plugin does not have.
• Widened the EQ response curve for legibility.
• Footer now reports a fixed 1x rate rather than implying a selectable oversampling stage. The engine runs at the host sample rate.
• Lane parameters are stated explicitly in the unlinked-lane tests, and the delegated processor contracts are covered by tests.
• Release builds can no longer report false-green test runs: assertions are kept live under Release (WsscAssertGuard).

Mastino 60

Punchy Multiband VCA Compressor v2.0.2

FIXED

View details

Mastino 60 v2.0.2 is a feature release. It adds per-band CLIP and clickable, plain-language help across the compression chart, makes the editor resize proportionally, gives the Gain Reduction Intelligence and Global panels more room, and fixes a handful of behaviour, stability, and gain-staging issues from the 2.0.x cycle. Existing projects, presets, licenses, and activations remain compatible. Every new control defaults to its previous behaviour, so a v2.0.1 session sounds identical until you reach for the new features.

X-Or

Mono sub-bass synth v1.0.3

FIXED

View details

Voice-handling hotfix for X-Or.

• Fast repeated notes (1/16 bass repeats, same note held and re-struck, lower-note steals, higher held-note arrivals while a note is gated) now produce a distinct attack on every key press. Previously the envelope could merge consecutive hits into one held note, especially with non-tiny decay settings - effectively a haunted sustain pedal. Every accepted note-on now restarts the envelope from zero (strict mono retrigger).
• Note releases now decay at the last played pitch instead of jumping to a fixed A. Previously, when a note-off emptied the voice stack the oscillator target collapsed to the internal idle pitch (MIDI A2) while the release tail was still audible, so every note's release tail rang as A. The voice state now latches the most recently sounding note and preserves it across the release tail; the idle pitch is only used at startup and after reset.
• Eliminated the audible click on hard retriggers with short attack and non-tiny decay. The strict mono retrigger above slams the loudness envelope to zero before re-attacking, which produced a step discontinuity (and an audible click) whenever the prior note still had gain - typically with loudness attack below ~0.8 ms combined with decay above ~12-15 ms. A short 2 ms crossfade at the VCA input now rides the prior loudness gain down to zero while the new attack rises, keeping the loudness output continuous without changing the retrigger semantic (the envelope itself still slams and restarts). The window is sized to mask the slam under all currently tested hosts including Ableton Live (which exposed residual crackle at a shorter 1 ms window).
• Pitch selection rules are unchanged: low-note priority still governs which held note sounds. Only the envelope retrigger and release-tail pitch behavior changed.
• Note-off uncovering a held higher note still does not retrigger - that case remains a smooth pitch follow with no fresh attack.
• X-Or remains transposed by design: incoming MIDI notes are still played one octave down, so MIDI A2 triggers A1.

• Added the Support panel with plugin, host, system, documentation, and diagnostic information.
• Fixed MIDI key-release handling for hosts and controllers that encode note release as Note On with velocity 0. X-Or now treats velocity-zero Note On as Note Off, preventing release events from retriggering or sustaining the voice.
• Hardened plugin/editor teardown so CLAP unload in REAPER is deterministic during project close and does not leave active DSP/analyzer or pending editor callbacks behind.
• Improved REAPER/CLAP shutdown behaviour when closing a project.
• Improved Windows graphics-cache cleanup during plugin unload.
