Sphere Flow Pocket

Read full description

Sphere Flow Pocket turns your iPhone into a 3D panning controller for immersive audio. Hold the glowing sphere on screen and move your iPhone through the air β€” the audio object in your DAW follows in real time, at full floating-point resolution. Let go and it stays. Reach a wall and you feel it click in your hand. No MIDI mapping, no mouse. Just move. HOW IT WORKS Sphere Flow Pocket connects over your local Wi-Fi network to the free companion AAX plug-ins for Avid Pro Tools. Insert SphereReceiver on a mono or stereo track β€” or SphereConstellation on a 5.1, 7.1, 7.1.2, 7.1.4 or 9.1.6 stem β€” and your motion is rendered in real time while every move is recorded as plug-in automation. Plug-in instances on your network are discovered automatically and appear in a one-tap menu. Communication is built on the open ADM-OSC standard. Full setup guide and plug-in download: reminitone.com/products/sphere-flow A CONTROLLER, NOT A SCREEN Pocket is designed to be used blind. Keep your eyes on your DAW: the iPhone in your hand is the controller, and haptics tell you what you cannot see β€” a tap when you grab, a knock when you hit a wall, a faint rumble as you slide along it, a click when the sphere snaps into place. Position is relative: every time you hold the sphere, the motion starts from where it is now, so you never have to reach across the room. FREE β€’ Mono panning β€” unlimited, forever β€’ Haptic walls, floor and ceiling β€’ Wall Snap β€’ CENTER β€” bring the sphere back to the middle of the room in one tap β€’ Adjustable motion range: 20 to 80 cm of iPhone travel across the full stage PRO (one-time purchase, 7-day free trial) β€’ Stereo β€” two spheres, front and back on screen; swap targets with one tap β€’ Constellation β€” take an entire 5.1, 7.1, 7.1.2, 7.1.4 or 9.1.6 stem as one object. Move it with your hand, turn and tilt it with your wrist, scale it with a slider or by dragging while you hold. Lock rotation or scale to protect what you have already written, reset either with one tap β€’ Physics β€” Throw with a swipe (the sphere flies the way you were moving), Gravity, Bounce. Every bounce is felt in your hand and recorded as automation Try everything free for 7 days, then unlock once to keep it. Mono panning stays free whether or not you buy. BUILT FOR ENGINEERS β€’ 6DoF motion tracking β€” real position in the room, not just tilt β€’ Float resolution over OSC β€” no 7-bit MIDI stepping β€’ 60 Hz position updates for dense, smooth automation β€’ Automatic discovery via Bonjour, manual IP connection as fallback β€’ Tracking-loss protection: the sphere freezes instead of jumping when tracking degrades REQUIREMENTS Sphere Flow Pocket requires the free companion plug-ins (AAX, for Avid Pro Tools) running on a computer on the same network: SphereReceiver for mono/stereo tracks, SphereConstellation for 5.1, 7.1, 7.1.2, 7.1.4 and 9.1.6 stems. Download and documentation at reminitone.com/products/sphere-flow. Motion tracking uses the rear camera; no images are stored or transmitted.
