AngstroLooper is old and not maintained by me any more, because time is short! If it works for you, that's great, if not ... look around for other alternatives. Sorry !
Angstrolooper is really a rediculously long delay, it partly emulates an old style tape loop system – but rather than trying to model something that it isn't, AngstroLooper is designed to be easy to use tool on a laptop while playing live.
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.
