Your teacher's displacement exercise. That 5-over-4 thing from a clinic. Ghost-note doubles at a tempo that scares you. Ten drill engines with every parameter exposed — configure exactly the exercise you need, run it hands-free, save it, and schedule it into a practice path.

Click displacement, polyrhythm, pocket, dynamics, accents, feel transitions, tempo builder, internal clock, time signatures, and the metronome itself — each one a configurable engine, not a canned exercise.
Odd meters included, with mixed subdivisions per beat — even triplets on one half of a beat and 16ths on the other. If the exercise lives on a grid, the grid bends to it.
Swing and pocket per voice, shuffle in the click itself, accents and ghost notes anywhere. Drill the feel, not just the notes.
Stack drills into a session with tempos and durations, hit start, and voice cues announce every transition. Sticks stay in your hands.
Every drill config you build lands in your library — organize them into collections, replay them any time, or share with a link.
Turn any drill into a multi-day plan: pick your practice days, set the tempo ramp, and follow a dated calendar until you've earned it.
