Invoke the sound under your fingers

Eight audio samples are arranged in columns, one next to the other. Placing and moving grain emitters on the grid, thousands of playheads can travel across the surface to build up delicate grain clouds, chopped breakbeats, dramatic orchestra scores and lush soundscapes – even all at the same time.

Tempera's powerful granular engine can produce movements, loops, chaotic scatters, and organized rhythms, all with precise scrubbing or broad sprays.

Tempera rear panel with connectors

Connected from edge to edge

Tempera is packed with connectivity. Loud and clear audio is delivered by a compact arrangement of two TS jacks as left+right, and a stereo headphones jack. You can sample incoming audio in mono or stereo, accommodating line-in signals, instrument signal, microphones, and pickups.

Integrate and sync clocks with other gear using MIDI TRS, compatible with both Type A and Type B wiring, or with your DAW through USB. Transfer audio files and canvases to and from your computer as a mass storage device. Connect USB MIDI controllers and keyboards directly into Tempera, or a USB flash drive for extra storage, or both with a USB hub.

Tempera offers a novel approach to sound design and manipulation.
Synth Anatomy
A fascinating take on granular synthesis. The first demos are pure ear candy.
Tempera looks very strokable, very interactive, and more like an instrument than a sample player.
Sonic State
Users are encouraged to listen and explore with their fingers.
