Fills go by faster than any ear can follow

At half speed a fill stops being a blur and becomes strokes you can count. The pitch does not move, so the kit sounds like a kit rather than cardboard. Loop the fill — the seam is click-free by construction, which matters more for time-keeping than for any other instrument — and creep the speed up through the presets as it settles into your hands.

A detail worth knowing: markers on each chorus make it quick to compare how the drummer develops the groove. Everything else SlowBird does — the searchable library, per-track memory, the five-band EQ — is described on the main page, and the core tools in depth under slow down, looping and notes.
