Fixed

• Sidechain waveform jitter between linked instances. When sidechaining one instance to another, the sidechain waveform could visibly jitter back and forth by one block each frame — worse at larger buffer sizes — on multi-core hosts that vary their per-block processing order. The linked read now stays phase-stable regardless of processing order.
• Sidechain input dropdown showing the placeholder after reopening the editor. When an instance was linked to another instance, closing and reopening the plugin window would leave the picker reading "Sidechain Input" even though the scope was still tracking the correct linked instance. The picker label now matches the active link.
• Auto delay compensation (ADC) was unreliable. Detection could either miss the transient entirely or always report a 50 ms offset, depending on whether the calibration window happened to overlap the transient. The detector now fires on the first sample whose absolute level exceeds −40 dBFS from the moment playback starts, so the reported offset matches the real transient position.

Changed

• Brighter grid and labels. The grey used for gridlines, labels, and readouts was lifted for better contrast against the dark background.
• Settings cog: defaults section now labelled. The Save / Restore / Factory buttons sit under a "Defaults" heading, matching the other grouped sections in the panel.

Added

• MIDI timebase mode. The scope timebase can now follow the frequency of incoming MIDI notes. Play a note into the track and the display shows a whole number of cycles of whatever pitch you're holding, phase-locked to the detected zero crossing at the left edge of the viewport — no horizontal drift, no jitter between notes.
• Octave offset (MIDI mode). A ±4-octave slider changes how many cycles are shown without changing the played note. Useful for switching between single-cycle detail and multi-cycle comparison.

Fixed

• Waveform stopping after extended use. Fixed an issue that could cause the scope to stop rendering during longer sessions. No action needed — the fix applies automatically on this update.
• Spectrum-hidden state not persisting across DAW reloads. If you dragged the spectrum panel fully closed, reopening the session would silently re-open it. The hidden state now persists as expected.
