RHYTHM CARDS — a shuffled deck of common rhythmic figures, each a single 2/4 bar. Tap PLAY to hear it, or turn CLICK off to hear it dry and fire instantly for quick flipping. Move through them with the arrows. The button up top-left filters by category, and tapping more than one blends them (it reads CUSTOM). Switch on TAP MODE and the pad takes over: tap it once to start, it counts you in, then tap the figure along with the click. The card grades your timing and points out what to fix. Hit TEST (top-right) for a rapid run of eight cards over a steady pulse, which scores you and targets the figures you struggle with most. BPM doubles as a difficulty dial: slow is forgiving, fast is unforgiving.

Each row is a drum track. Tap a step to add a hit and it lights up. Long-press for a ghost note (quieter, shown dimmer) or flam (double strike). Hold the track label on the left to open the precision editor, where a TIMING tab pushes single hits early or late. Load a PRESET below to hear a complete pattern, then change it from there.
