AI drum practice rig

Make any song a drum lesson.
In minutes.

Drop in this week's track. DrumShell isolates the kit, slows the fill, and loops the weak bar until it locks. No laptop. No DAW. Just the phone beside your kit.

3 free splits/week / 0.70-1.50x / A/B loop

Practice controls

Everything you reach for when the bar is not landing.

How it works

Import. Split. Practice.

Get the drums out, slow the hard part down, and repeat it until the hands know it.

Proof from the practice room

Built for weekly sets, lesson prep, and gig calls.

DrumShell completely changed how I learn new songs. I can strip the drums out of anything and work through the parts at my own pace. The stem quality is insane.
