Live Step Designer (LSD) is a step sequencer that is especially created for live-manipulation of loop regions and controls. NEW: Polyrhythm function (beat to next beat division) and Swing percent ! You can use LSD with GM (General Midi), for example with your soundcard, with external synths, samplers or drumboxes, and, if you install a "Midi loop back" (ex: Midi Yoke), with software-synths like Reaktor, Absynth, etc...
