Pour

Pour is a Mid/Side stereo imager with a live polar vectorscope. Shape your stereo field with the full set of M/S controls — Shuffle + Space (Blumlein bass stereo shuffling), Width, Rotation, Asymmetry — plus Solo Side monitoring so you can hear exactly what collapses on mono fold-down. Inspired by the SSL Fusion Stereo Image hardware and Alan Blumlein's 1931 Stereo Shuffling.

Key features:

• Shuffle + Space — Blumlein bass stereo shuffling with a 40–400 Hz crossover. Wider low end without killing mono compatibility.
• Width — ±6 dB side gain for classic widening or narrowing.
• Rotation — ±45° M/S vector tilt (Waves S1 style).
• Asymmetry — phantom center shift without affecting overall width.
• Live polar vectorscope with persistence trail.
• Solo Side button — audition stereo-only content.
• M/S metering on input + output.
• Pop-up preset browser (Bass, Vocal, Drum, Guitar).
• A/B compare and 64-step Undo / Redo.
• Zero latency, low CPU.
