A Free Tool for Granular Ambisonics
Puremagnetik's Micah Frank has published an open source performance workstation designed to build realtime, evolving sound sculptures with optional ambisonics.
Harnessing the audio processing power of Csound, Grainstation-C seamlessly integrates with a Novation LaunchControl XL Mark 2 (easily modifiable for any other controller) and can processes 4 disk tracks and 3 live input streams.
You can save any state as a snapshot and morph to that snapshot at any point in a performance. It has 6 independent pitch delay lines, 6 switchable low pass and high pass filters, live audio looping and multiple granular processing controls including granular time-stretching, frame animation and granular pitch shifting.
Micah built the program to farm textures and granular structures for his latest album Quetico - out now on Puremagnetik Tapes. With this work he has been awarded a 2019 NYSCA/NYFA Artist Fellowship in Music and Sound from The New York Foundation for the Arts.
