The devices are designed to generate randomization effects.
Developed by Sonic Faction, it contains five step sequencers and "idea generators" that add an element of controlled randomization to performance and composition. Each device has a different way of introducing variations into loops and sequences, from subtle interventions to more extreme ones. The tools are built for hands-on use with Push hardware, but it's not necessary to use the software.
