Not a trial. Not a demo. The full oscilloscope — yours to keep.
Resize to any size. Clean rendering up to 4K at any window size.
Minimal CPU. Light enough to run on every track that matters.
Overview
Scope gives you a clear, accurate view of your signal in real time. Beat-synced or free-running, sharp at any size. Zero latency. Minimal CPU. If you find yourself wanting to compare two signals, isolate a frequency band, or measure a waveform — DeltaScope adds those capabilities.
Lock your waveform to the tempo for repeatable, stable views.
22 beat divisions from 1/128th note to 16 bars — straight, dotted, and triplet. PPQ-snap locks transients to the same position every cycle. Free-run mode available for Hz and ms-based time windows.
Your waveform stays locked to the beat — every division from 1/128th note to 16 bars.
PPQ-snap locks transients to the same position every cycle — no jitter, no drift.
Switch to Hz or ms-based time windows when you don't need tempo sync.
Scale the display from -36 dB to +36 dB to focus on the detail that matters.
Full visual quality from the DeltaScope rendering engine.
Custom waveform colours. Polarity-aware clip detection. Resize the window to any size — the display stays sharp and responsive, up to 4K.
Set your waveform colour to match your workflow or preference.
Polarity-aware indicators on the scope border — top for positive clips, bottom for negative.
Drag the window to any size. The display redraws cleanly at every resolution, up to 4K.
Left, Right, Mono, or Stereo — switch instantly.
