Nothing in testing right now. Changes that are coming in the next version will appear here.

v1.1.0.1415 released 17 October 2026 Current

Improved

  • The reverb now has a Decay control. The default Hall tail is shorter than before, and older projects are converted to sound the same.
  • The 24 dB band-pass and notch filters now sit at the same level as their 12 dB versions, instead of being louder or quieter.

Fixed

  • Fixed the loudness of the Fold, Soft Clip and Hard Clip effects, and fixed the sidechain ducking, the Compressor and the 12 dB band-pass filter.
v1.1.0.1412 released 15 October 2026

New

  • Pay What You Want, from £0 and suggested £20 (GBP).
  • New Support window and licence-key entry. The key you get by email, even if you pay £0, removes the Support window. Nothing in the app is limited either way.
  • The Pay what you like button now opens the new Pay What You Want page.
v1.1.0.1411 released 15 October 2026 · replaced by v1.1.0.1412

No changes to μ-tant in this release. It was published together with the first releases of μ-toni and μ-on.

v1.1.0.1410 released 13 October 2026

New

  • A Performance chooser (standalone): build, save, rename and delete lists of up to 8 presets and load one for Performance mode, from the Performances... entry at the bottom of the preset dropdown, or from the Perf button when no performance is chosen. (1597)
  • New Swap choice in the Master Loop pane: pick when a swapped-in preset takes effect, at the end of the Master loop, the Voice loop or the Bar. It also adds a new automatable Swap parameter to the parameter list, so automation lanes in projects you saved before may line up one slot off. Please check them. (1596)
  • New Performance mode (standalone): the Perf button locks the screen for live use and shows a step indicator with your queued switches. Hold Perf for one second to leave it. (1328)
  • No more demo limits: every copy has all eight tracks, full step counts and preset saving, with or without a licence key. (1348)
  • The activation window has a Get a key button that opens the pay-what-you-like page. (1355)
  • μ-tant is now free to use, pay what you want. Copies without a licence key show a polite support message once per session (with a "don't show this again" option), a Support link in the status bar, and Support and Enter a key buttons in About. (1164, 1347)

Improved

  • Mixer faders now have a knob-style cap with a lit groove, instead of a small white dot. (1599)
  • The modulation depth and curve controls on the Matrix and the modulator editor now use the modulation colour. (1599)
  • The level meters in the plugin mixer are now stereo. (1595)
  • The voice page now shares one layout with the other apps: the gate editor grows to use the spare height, the filter rows sit closer together, and the wavetable names fit their selectors ("Basic" and "Pulse" replace "Basic Shapes" and "Square PWM"; saved sounds are unchanged). (1505, 1506)
  • Knob labels stay put: they no longer show units and no longer change when you turn a knob (the status bar shows the value and units as you turn). (1526)
  • Loading a preset or voice pattern while a host, MIDI clock or mu-link is playing now waits for the voice's loop to wrap, like everything else, instead of cutting in mid-loop; a load can no longer get stuck waiting if the clock disappears or you press Stop at the same moment. (1400, 1402)
  • Settings now uses two columns, so every option fits on screen without cutting off. (1352)
  • Mixer and MIDI program-change lists lay out correctly when a banner is showing, and the master EQ and side-chain knobs no longer crowd their panels. (1356, 1357, 1358, 1359)
  • New Tap button in the transport bar (standalone): tap the beat to set the tempo. It shares its place with the MIDI clock lamp, so you see Tap on the internal clock and the lamp when following a MIDI clock. (1253)
  • New Nudge buttons (− and +) next to the position display (standalone): hold one to run the groove 4 % slower or faster and pull it back in time with a drifting master; let go and the tempo is exactly as set. Under an external MIDI clock the shift stays until the next Start. (1253)
  • New Sync offset in Settings (MIDI Clock section, shown when the clock source is MIDI In): enter your audio output latency (about 20–40 ms) and the app plays that much earlier, so it lands on the beat with a hardware master. Saved between sessions. (1253)
  • New Time signature choice in Settings (Transport): the position display counts in 2/4 to 12/8 instead of always 4/4. Patterns still run in four-beat bars. (1295)
  • Apps connected to μ-link now respond about twice as fast to Stop, mutes, knob moves and preset changes (about 85 ms behind instead of about 170 ms), and your MIDI keyboard feels the same shorter delay. (1256)
  • The BPM field now takes a tenth of a BPM (20.0–300.0, e.g. 127.5): the arrows step a whole BPM, Shift+click steps a tenth, and you can type a value. μ-link’s tempo control does the same. (1296)
  • MIDI clock sync in the standalone is much tighter: the beat now follows the external clock smoothly instead of in steps, so patterns and gates line up with a hardware master within a fraction of a millisecond (they could land up to a clock tick late, about 20 ms at 120 BPM, and wobble with the clock). The first clock after Start now counts as the downbeat, as the MIDI spec says. (1259)
  • μ-link slaved to an external MIDI clock now keeps its grid on the master’s downbeat instead of keeping whatever offset it started with and slowly creeping. (1257)
  • MIDI clock sync in the standalone: a new “Clock” lamp in the transport bar shows whether the clock is coming in (amber = waiting, green = locked, red = lost). If the clock stops arriving while playing (a pulled cable, say) the app stops instead of running on, and carries on when the clock comes back. (1252)
  • The MIDI clock “Messages” choices are now named “Clock only”, “Transport only” and “Clock + Transport”. They work as before. (1291)
  • With μ-link connected, the standalone now hears your MIDI keyboard and controllers (it used to ignore MIDI while connected). For now there is a short delay of about a tenth of a second while connected. (1255)
  • In a DAW, the transport bar now counts bars and beats in the song’s time signature (3/4, 7/8 and so on) and lines up with pickup bars. (1251)
  • MIDI clock sync in the standalone now follows Song Position Pointer: when your hardware sequencer jumps to a new point and continues, the app continues from the same point. (1258)
  • μ-link’s MIDI clock output is now evenly spaced (it used to arrive in bursts) and also sends Start, Stop, Continue and song position, so outboard gear follows play, stop and rewind. Changing μ-link’s MIDI output while playing no longer resets the tempo or position. (1254, 1258)
  • In a DAW, the transport display (play button and bar position) now follows the DAW more reliably, including while the plugin is bypassed. (1243)
  • The plugin window uses less CPU: knobs, step editors and animations only redraw when something on screen actually changes, and hidden panels stop animating. (1242)
  • In a DAW, the gate patterns now line up with the DAW’s bars and follow its loop and position jumps (they used to run from wherever they started). (1188)
  • With MIDI clock sync on in the standalone, the clock’s Start and Stop now control playback fully — its Stop stops the app even if you pressed Play. (1188)
  • Presets and saved projects now store each setting's real value (and choices by name), so a future update that changes a knob's range can't shift a saved sound. Older presets and projects still load as before. (1237)
  • Presets and projects saved with this test build won't open correctly in earlier builds — keep a copy if you go back to an older version. (1237)
  • The preset list and the Save dialog open faster, especially with lots of presets or presets that carry embedded samples. (1234)
  • The mixer page starts to take on the metal look: the channel strips and the effects rack sit on screwed metal panels, and each effect row is in its own raised box. The knob-size test knobs are gone. (1181, 1182)
  • The gate pattern editor now has the metal look: its controls sit in a raised box and the envelopes light up on a screen set into the panel, like the modulator display. (1179)
  • Every knob on the main page is now μ-tant green. (1178)
  • Each oscillator's level is now a Level knob at the end of its own panel, and the noise level sits next to a smaller noise-type selector; the separate Mixer box is gone, giving the filter more room. (1175, 1176, 1177)
  • The status bar at the bottom now shows each control's name and value as you hover over it or turn it, as in μ-clid. (1165)
  • Screwed metal panels like μ-clid's: each voice section (oscillators, X-Mod, filter, effects, mixer) sits in its own raised box with its name on a plate above it, the panels have cross-head screws in their corners, and the modulator display is taller. (1163)
  • New colours: the panels look like green paint on brushed metal (darker and less glowing), and each voice has its own colour that lights its sidebar icon, its name and its preset selector. (1147)
  • The voice preset list is now sorted by name. (1138)
  • New look: brushed-metal panels in μ-tant green, LCD-style dropdowns and tabs, engraved labels and name plates, matching μ-clid. (1120)
  • Knobs cast a soft shadow away from the top-right light, so they sit up off the panel.
  • Stepped knobs now show one tick per position around the dial, so you can see how many settings they have.

Fixed

  • In CLAP hosts, the plug-in’s parameters now refresh correctly after a preset or session loads. (1590)
  • Fixed a hang when the plugin was unloaded, and a knob whose range shrank to nothing (for example an insert with no room to move) no longer trips a warning in test builds. (1322)
  • Deleting or re-ordering rhythms (μ-clid) or voices (μ-tant) no longer leaves a channel ducking from the wrong one: sidechain sources now follow their rhythm / voice, and a channel that ducked from a deleted one stops ducking. (1308)
  • MIDI clock sync in the standalone: with Messages set to “Clock only” the Play button now starts the app (it used to stay stopped), and with “Transport only” the app now plays at its own BPM instead of sitting on the first step. (1261)
  • Loading a voice preset saved before some settings existed now puts those settings to their defaults, instead of keeping the previous voice's values. (1237)
  • Presets are grouped under their categories in the preset list again, the preset browser shows each preset's category and description, and Save fills in the current preset's category. (1233)
  • A preset saved with Save → Save as Default is now restored when μ-tant opens, as in μ-clid. (1231)
  • When following external MIDI clock, the tempo is now right from the first beat after Start — it used to run fast (or at the previous tempo) for about a beat. (1232)
  • If a preset can't be saved (for example a full disk or a read-only folder) you now get an error message instead of nothing, and an interrupted save can no longer leave a half-written preset. (1230)
  • Modulating X-Mod Index, X-Mod Depth or X-Mod SSB now moves them by the depth you set — they were reacting about 100 times too strongly. (1121)
  • The status bar now names insert-effect knobs after the chosen effect — "Compressor Threshold" rather than "Insert Threshold". (1102)
v1.0.0.971 released 2 October 2026

Improved

  • New knob design throughout — raised dials with a glowing ring and a single dot marking the position; stepped controls show their value in the centre. Knob labels no longer carry units (the status bar shows them as you turn).
v1.0.0.926 released 17 June 2026

New

  • Master Loop control in the transport bar (like μ-clid) — pick a loop length and see the step counter. (1010)
  • Hot-swap timing setting — choose whether preset / program-change swaps land on the master loop or on each voice's own loop, for musically-timed changes. (1011)
  • External MIDI clock sync (standalone) — slave μ-tant's tempo and transport to incoming MIDI clock. Set it under Settings → MIDI Clock. (1012)
  • Note mode — play μ-tant like an instrument: the drone sounds only while a MIDI note is held, and the held note sets the pitch (works in a DAW and from a keyboard in standalone). Switch it on under Settings → Note Mode. (1012)
  • Redesigned X-Mod — two lanes instead of three fixed knobs. Lane A: one Index knob with FM / PM / TZFM modes, plus Sync and Feedback. Lane B: a bipolar Depth knob with AM, RM and SSB (single-sideband frequency-shift) modes — from tremolo-like amplitude mod through clangorous ring mod to shimmering inharmonic drones. Existing presets are carried over automatically. (1019)
  • The plugin now tells you when a newer version is available — a banner appears along the bottom showing your version and the latest one, click it to go to the download page. (1026)
  • 100 new factory voice presets (drones, pads, basses, leads, textures, rhythmic) and 100 full presets combining them with effects — in the Voices and Presets browsers. (1029)
  • All filter controls — cutoff, resonance, drive and low-cut — for both filters are now modulation destinations, grouped as Filter 1 and Filter 2 in the destination list. (1030)
  • Pitch-envelope depth (per oscillator) and filter-envelope depth (both filters) are now modulation destinations too. (1034)

Fixed

  • Fixed a potential click/dropout when using modulation — the modulation engine no longer allocates memory on the audio thread. (1039)
  • Fixed a potential click/dropout when automating reverb or effect parameters — these no longer allocate memory on the audio thread. (1040)
  • The in-plugin update check now runs once per session instead of on every window open. (1038)
  • Aligned the Close button on the MIDI program-change preset tables. (1032)
  • Fixed garbled characters in the MIDI program-change "Full Presets" table heading. (1014)
  • Fixed the filter envelope (gate editor's FILT layer) barely moving the cutoff — it now follows the drawn shape and sweeps the filter as intended. (1020)
  • Pitch now glides smoothly — the pitch envelope and smooth modulators sweep continuously instead of stepping in semitones. Step modulators still snap to semitones so you can write melodies. (1021)
  • Step modulators now snap their drawing grid to the target's musical units — an octave target gives 3 steps up/down, a scale-degree target 12 — so you draw notes directly instead of guessing heights. (1022)
  • Octave is now a step-only modulation target — it's hidden when a modulator is in Smooth mode, since a continuous octave glide isn't musical. (1023)

Improved

  • The factory presets have been completely reworked — every voice now has its own evolving gate pattern (no more flat held drones), the rhythms are more musical and leave space so layered voices play off each other, and the combined presets pair voices that complement one another. (1042)
  • Switching to a preset with fewer voices while playing now fades the removed voices out smoothly, so their filter/effect tails ring out instead of cutting off. (1013)
  • The Settings page has been restyled to match μ-clid — grouped General and MIDI sections with clear headings, dividers and a consistent layout. (1004)
  • Settings controls are now left-aligned and indented under their headings, with a Contact Support link at the bottom. (1031)
  • Oscillator knobs reordered — the Pitch Env knob now sits with the pitch controls (Oct / Semi / Fine) and wavetable Position is last, so it no longer reads as a "position envelope". (1033)
  • The modulator destination list now hides the Insert effect targets when no insert effect is selected. (1035)
v1.0.0.865 released 13 June 2026

Improved

  • In a DAW, the transport play button now turns into a stop icon while the host is playing — matching the standalone. (994)
  • Transport bar polish: clearer play/stop state and tidier spacing and labels. (990, 991)

Fixed

  • Fixed a rare crash on launch that could occur when a saved online-activation file was present. (995)
  • Fixed knobs accidentally changing value when you scroll over them in a DAW (e.g. while scrolling the timeline). (988)
v1.0.847 released 12 June 2026

New

  • Demo mode: try the full synth with a single voice; saving is disabled until you activate a licence. (981, 982)
  • The sidechain input now appears in CLAP hosts such as Bitwig, matching VST3. (969)

Improved

  • New modulators now start in Unipolar mode. (968)
  • The modulator step grid now lines up with the actual step length. (963, 967)
  • Double-click a modulator node to delete it. (962)
  • Modulation curves no longer overshoot the visible range when bending. (957)
  • The master meter and fader now reflect the master insert effects. (965)

Fixed

  • External (DAW) sidechain now ducks correctly — previously it could produce no ducking at all. (974)
  • Fixed a possible crash at high sample rates (88.2 kHz and above) in the Chorus effect. (961)
