Release date:

Sun, 02 Aug 2026 20:54:17 +0300

New features:

• Store the render settings with the song

• Add optional multi-threaded playback

  • "Spread playback across CPU cores" in Audio settings, off by default

• Add DSP load metering to the Device Rack

• Add gain staging with a selectable fader position

  • Each rack slot now has a peak/RMS level meter, tapped post-gain and
    pre-insert, with a -18 dBFS marker to gain stage against
  • The Volume knob is now labelled Fader in every device and sits below Gain, in
    signal-flow order; it was previously called Master Volume, Volume or Global
    Volume depending on the device

• Add a String Ensemble device

  • Inspired by Solina String-Ensemble

• Add a Sub Mixer device

  • Groups other devices so a whole set is mixed and processed as one entity,
    e.g. everything except the lead synth through a single compressor

• Add an Air Band EQ rack effect

• Add a Simple EQ rack effect

• Add a Vintage Passive EQ rack effect

• Add Pattern Peek to the editor

  • Toggle via Settings => General => Editor => "Pattern Peek" (on by default)

• Add Move to Top/Bottom to the rack effect Manage menus

• Add FLAC support to the Sampler

• Add selectable audio quality (oversampling) for playback and export

  • Separate "Playback quality" (Audio settings) and export "Quality"
    (Render dialog): Draft (1x), Normal (2x) or High (4x)

• Add a Drive rack effect

  • Overdrive with Drive amount, dry/wet Mix and an output Gain (dB) knob

• Copy an existing device or effect when creating a new one

  • "Copy Device..." in the Device Gallery duplicates another device into the slot
  • "Copy Effect..." in the Effects Gallery duplicates another effect in the same rack
  • Add direct "Import Effect..." to the Effects Gallery, matching device import

• Add a stereo oscilloscope to the Synth

  • Live L/R waveform traces side by side on a new "Scope" tab

• Add per-pad and per-voice insert effects

• Add a gate to the Reverb (gated reverb)

• Add Endless Reverb rack effect

• Add Mid/Side processing modes to the 8-band parametric EQ

• Add a mastering Limiter rack effect

• Import an exported device directly from the Device Gallery

  • New "Import Device..." button creates the device from the exported settings
  • The device type is taken from the file, so there's no need to add a device first

• Add a per-rack Enable switch to all effect racks

  • Header-level switch (on the left) bypasses the whole rack when off; on by default

• Add chromatic mode to the Sampler

• Store the auto note-off offset with the song

  • New Song => Settings menu, with an optional BPM sync mode (1/4 .. 1/128,
    including the 1/24 and 1/48 triplets)
  • Channels can override both the offset and the mode in their timing settings
  • The application-wide setting is now the default new songs start from
  • Lower that default from 250 ms to 25 ms, which existing settings keep

• Let modulation stay where it sweeps to

  • A finished one-shot LFO now holds the value its shape ends on instead
    of snapping back to zero
  • Add a Sustain control to the Mod EG of the Synth and Wavetable Synth,
    0 keeping the previous AD behaviour

• Add Supersaw and Drift voice modes to the Synth

  • Supersaw spaces the detune unevenly around a centre voice held at full
    level, so the stack keeps a core pitch instead of smearing it
  • Drift replaces fixed detune with per-voice wander, so no pair settles
    into a steady beat
  • Both roll the top off the outer voices, where the beating is roughest
  • Switching voice mode no longer changes the level

• Make the Device Rack's gain staging target configurable

  • "Gain staging target (dBFS)" in General settings, -18 by default

• Add an Auto Ducker rack effect

  • Side chain driven level rider whose Amount is signed, so it ducks or lifts

• Extend faders to +10 dB, on devices and Sampler pads

  • Unity now sits three quarters up the throw; existing projects keep their gain
  • Internal devices report their own MIDI CC ranges, so CC 7 automates the
    whole fader; external ports stay on the MIDI 1.0 range

• Add a clip LED to every Device Rack row

  • Latches on any full-scale output, clears on click

• Draw automations as curves over the tracker lines

  • Each automation on a column gets its own vertical trace, value left to right,
    so a sine modulation reads as a sine
  • Settings => General => Editor => "Automation display" switches back to Tint

• Add Help => What's New

  • Shows the bundled CHANGELOG from the latest release onwards

• Make the automation curve thickness configurable

  • Settings => General => Editor => "Automation line thickness"

• Make the edit cursor color configurable

  • Settings => Theme => Colors => "Cursor color"

• Add Settings and Master effect rack to the Song context menu

• Mark every menu action that opens a dialog with an ellipsis

• Add a table of contents to the user manual

  • Sections are listed in a sidebar and clicking one scrolls the manual
  • Cross references inside the text jump to their section
  • The manual now follows the theme accent instead of a fixed orange

• Blend the track and automation colors towards the accent color

  • Settings => Theme => Colors => "Accent blend"
  • 0 % is the original palette, 100 % puts every color on the accent hue

• Redraw the track and column velocity scales in the accent color

  • Flat and gray at 100 %, so only scaled tracks and columns stand out
  • The tooltip now states the current value

Bug fixes:

• Fix a stutter on the first play

• Fix the Drum Synth allocating memory on the audio thread every callback

• Fix voices never ending when a patch has zero sustain

• Fix high frequencies being attenuated at 2x and 4x oversampling

• Fix drum voices changing character with the oversampling factor

• Fix Panner rack effect Width knob having no effect

• Avoid copying the send effect list on every audio callback

• Fix per-buffer heap allocation in the Sampler audio path

• Fix audio stutter by processing real-time playback single-threaded

• Fix audio stutter from rebuilding the processing graph every buffer

• Fix Sampler global switches not updating when switching instance

• Fix crash when importing a device with embedded samples

• Fix rack Delay effect mode selector (Mono/Ping Pong/Tape had no effect)

• Fix rack Delay effect manual (non-sync) time knob clamping at ~11 ms

• Fix Synth Multi engine ignoring Key Track in the High, Low and Peak modes

• Fix Unison being far louder than Poly in Synth and Wavetable Synth

• Fix the render progress bar starting at the previous export's value

• Fix the Clipper's reduction meter reading near full scale at all times

• Use the configured auto note-off offset when rendering to audio and when
  exporting MIDI

  • Both used a hard-coded default unless the song had been played first
  • Channel overrides were applied correctly and are unaffected

• Fix a disabled automation still colouring its column red

• Fix automation playback costing far more CPU than it should

  • Every MIDI CC event reset the Device Rack model and rebuilt the port lists

• Fix playing a song with automations marking it as modified

• Remove the empty space above the first main context menu item

Other:

• Speed up rendering and export by cutting the worker pool's synchronisation cost

• Make the Drum Synth's Clap darker at low Tune settings

• Add NOTEAHEAD_AUDIO_WORKERS env var to tune the render worker threads

  • Controls how many worker threads offline rendering/export fans out across
    (0 = single-threaded rendering); real-time playback is always single-threaded

• Double the maximum number of devices and effects per rack to 16

• Update README's device and effect listings

• Update the user manual for the current devices, effects and render options

• Hold the DSP load peak before letting it fall, so spikes stay readable

• Sample automation values directly when drawing the editor, instead of
  rendering throwaway events for every visible line on every repaint
