About this app
sectors is an AUv3 surround panner for quadraphonic speaker setups on iPad. Designed for composers, sound artists, performers, and installation artists, sectors lets you position and automate sound in a four-speaker environment with an intuitive X-Y pad. You can use Orbit to spin the sound around the room, Random to make it jump between four speakers or Trace to capture your movement on the X-Y pad and loop it. X-Y Pad Place sound anywhere in the room with a touch. Drag the puck across the pad to smoothly position sound anywhere in your quadraphonic space. Spread Control how tightly sound gathers around the puck's position. Wide open, the field blends smoothly across all four speakers. Dial it in for a precise, localized point. Orbit Sweeps the sound around your speakers on a true circular path, clockwise or counter-clockwise. Change the speed using the rate knob, or sync it to your host. Random Lets the sound drift and jump around the space on its own, creating movement that never repeats itself. Trace Record your movement across the pad in real time and loop it back exactly as performed. Sync playback to the host tempo or let it run freely. Your path saves with your session. Please note that this is an AUv3 plugin and requires a host app like AUM to function as intended. For quadraphonic output you will need an audio interface with 4 outputs. Without a quad setup, you can try the experimental binaural headphones output.
What's new
Version 1.1 · Nov 2, 2026
- Host sync now locks to the beat and restarts with your transport - Orbit can run clockwise or counter-clockwise - TRACE paths stay when you switch off, and save with your session - Interface fills the window, with a wide layout when you stretch it - Smooth movement under MIDI control - Experimental binaural headphones output for those without quad setups - Less level drop when you add sectors to a channel - Stability improvements Note: Spread now reads 0 = tight, 100 = wide on the knob, in MIDI and in automation. Sessions saved in the previous version will load with Spread reversed, and may play slightly louder in the middle of the pad.
