Giada is a free, minimal, hardcore audio tool for DJs, live performers and electronic musicians. How does it work? Just pick up your channel, fill it with samples or MIDI events and start the show by using this tiny piece of software as a loop machine, drum machine, sequencer, live sampler or yet as a plugin/effect host.
Regen is at its heart a looper plugin that is well suited for ambient / textural / soundscape type layering. It can be a simple looper but also offers deeper dive controls to modify playback of recorded material.
