Knob Lab turns your iPhone or iPad into a MIDI controller built around one idea: a single knob can do many things at once. ONE KNOB. MANY MOVES. Map a knob to up to 8 MIDI destinations. Each has its own range, direction, channel and colour, so one turn can open a filter, pull the resonance back and bring the delay in over the second half of the sweep. BUILD YOUR OWN MACROS • Control Change, Program Change and Pitch Bend destinations • Name every knob and every destination, so a setup reads at a glance • Invert any range, or start a destination part-way through the turn • Rotate completely, snap to middle, pan left/right, or return to origin on release • A coloured lane for every destination shows where each one is A LAYOUT FOR EVERY SETUP Start with one big knob, or unlock layouts with 2, 6 or 12 knobs on a single screen. PLAYS WITH EVERYTHING • Music apps on the same device, through Knob Lab's virtual MIDI output • Computers over Wi-Fi, with a network MIDI session • A Mac over USB or Bluetooth, with Sonic Logic Central • Class-compliant USB MIDI interfaces and synths plugged into your iPhone or iPad MADE FOR TOUCH Large, precise knobs, a quick guided start, and Dark, Light and Neon themes.
