About
A drummer to practise with. Pick a beat, set the tempo, and play.
Automatic Pocket plays drum beats recorded on a real kit, and the drummer behaves like one: fills at the end of the phrase, a switch to the ride for the next section, a crash on the way back in. It works on the speaker or in headphones, with nothing to set up.
The beats
• 36 beats across rock and pop, funk and soul, hip-hop and electronic, Latin and Caribbean, swing and shuffle, plus bare clicks for slow practice.
• Any tempo from 40 to 200, changed while the drums play.
• The kick pattern on screen, with a line that moves in time, so you can see what to lock to.
The drummer
• Fills written for each style, every 4, 8 or 16 bars, half a bar or a whole one.
• Switches the beat up every 8 or 16 bars, and comes back.
• Drops out for a few bars while you keep time on your own.
• Drifts the tempo for you to follow.
Your own beats
Tap a beat into the editor: ten drums, straight or triplet steps, loud, soft and ghost notes. Your beats sit next to the built-in ones.
Score my timing
Want to know how tight you are? Put headphones on and play a note on every kick. The app listens to your bass through the microphone and shows how early or late each note was, then gives you a score and the kicks you rush or drag. Notes between the kicks are free.
Made for bass players. Works for anyone who would rather practise to a drummer than a click.
