ScopeNode

ScopeNode is a multi-input oscilloscope, capable of visualizing multiple tracks layered on top of each other. The plugin features a suite of phase alignment tools built around an interactive visual workflow tailored specifically for the low end. These can help eliminate low-frequency clashes at the source so your tracks layer perfectly without heavy reliance on aggressive sidechain dips. The result is a much smoother, more fluid bass response. Beyond phase alignment, ScopeNode is perfect for visualizing how individual components line up, checking delays between signal points, or analyzing precise pre and post waveform differences across third-party plugins or subchains. FEATURES: - Free-Running & Beat-Synced Modes - 4-Layer Scope Matrix + Live Summing: Layer up to four audio tracks simultaneously with a real-time composite summing view for instant clash detection - Separate controls for visualization and sum inclusion to accommodate special use cases (optional) - Phase shifter with configurable center frequency and Q factor (one per track) - Sample grid delay, phase invert, gain control also available for each track - Multi-instance workflow: Drop plugin instances ("probes") anywhere in your signal paths to capture and compare tracks instantly TECHNICAL NOTES: - When enabled, it's recommended to verify that Plug-in Latency Compensation is not affecting synchronization in unexpected ways with the given set of active third-party plugins - Manual phase alignment is an advanced, hands-on process that requires time and active engineering effort, depending on the complexity of the tracks involved - Workflows could be greatly impacted by specific features of your DAW, e.g. ease of automation envelope editing, ways of laying out multiple viewports, etc. PLEASE NOTE: • An AUv3-compatible host is required to use this app (true interoperability can vary across different apps) • Please check our support page for a list of compatible host applications • Officially supported sampling rates: 44.1, 48, 96 kHz
