Ambient Engine Releases Notes

v1.2

July 28, 2026

Completely replaced with a newly developed stereo delay. You can set Wet / Feedback / Time (10ms–5000ms). Increasing Feedback adds analog-style saturation. We also reduced noise when changing Time.

Completely replaced with a newly developed reverb. You can switch between three types—Room / Plate / Shimmer—and fine-tune space and decay with Wet / Size / Time. Shimmer is a bright, expansive ambient sound with boosted highs.

Added a new Flutter knob to the Drive section. It adds tape-machine-like wow flutter (pitch wobble); the higher the value, the deeper the wobble.

Rebuilt the loop playback engine as a dedicated audio unit to reduce click noise at loop boundaries. Time is now displayed in ms (10ms–5000ms).

Integrated the HI / LO / BAND / COMB filters into a new engine, making changes smooth even during fast Cutoff / Q modulation.

Replaced with a newly developed Drive, so the amount of distortion now changes smoothly without noise even during fast knob moves or modulation.

Presets created in v1.1 or earlier will play back with the previous Delay / Reverb sound. Use the `Upgrade` button on the panel to migrate Delay / Reverb to the new engine individually (settings are mapped automatically).

You can now MIDI Learn / assign Flutter and each parameter of the new Delay / Reverb.

When using the new effects, the Master section is now displayed in a two-column layout alongside the right side of the Spectrum Analyzer.

Presets now store the version they were created with. If you open a preset made with a newer version than the one you’re using, a warning with version info is shown and the operation is safely aborted.

Fixed an issue where pop noise could occur during window operations (toggling fullscreen, switching apps, right after saving a recording, etc.).
Fixed an issue where noise could occur when adjusting Filter Cutoff or during modulation.
Fixed an issue where noise could occur when adjusting Samples > Sample Pitch.
Fixed an issue where noise could occur when changing per-Voice pitch or MicroLoop pitch.
Fixed an issue where noise could occur during fast Drive knob moves or modulation.
Fixed an issue where the Voice Timer playback interval could become inaccurate around ~50ms.

Fixed an issue where repeatedly muting Voices could cause the app to crash.
Fixed an issue where loading another sample during playback could prevent the sound from switching, stop the playhead, and eventually crash when repeated.
Fixed an issue where the audio graph could restart when waking from sleep or while audio was stopped.

Fixed an issue where animations such as the Voice progress bar and spectrum display could stop or stutter while dragging a knob.
Fixed an issue where background gradients (e.g., Aurora) could stutter during knob operations.
Fixed an issue where a white background could briefly appear on launch, and an issue where the window could briefly look like it shrank.
Fixed an issue where the background color right after launch didn’t match the theme.
Fixed an issue where the playback position bar didn’t follow when changing Sample Pitch / Voice Pitch.
Fixed an issue where the playback position bar could gradually drift between Voices during loop playback.
Fixed the playback position display when changing the playback range (slice).
Fixed the waveform progress display when Random Range is enabled.

Fixed an issue where MicroLoop might not work in the state immediately after launch.
Fixed an issue where Density modulation wasn’t reflected in the trigger rate of Random triggers.
Fixed an issue where operating another knob during modulation could write back the in-motion value to the engine.
Fixed an issue where changing/removing a modulation target wouldn’t correctly restore the original parameter value.
Fixed an issue where the global pitch setting could be applied twice on MIDI note-on / pitch bend.
Fixed an issue where value mapping near the maximum of the Voice Timer wasn’t correct.

Fixed an issue where, when opening a preset and saving as a new name, the original sample files wouldn’t be copied in “Keep Original Files” mode and would be converted to WAV instead.
Strengthened validation for preset files received from external sources (rejecting invalid file references, preventing excessive volume via range checks on settings, etc.).
