A multiplayer beat maker in the browser

Make beats together in real time: a pattern sequencer, piano roll, song timeline and mixer on the big screen, and every friend editing from their own phone.

What's inside

• Patterns: every track has A, B, C… patterns of 1 to 16 bars, with a step grid on the phone.
• Piano roll: draw, select, move and resize notes, with velocity per note, snap from 1/4 to 1/32 and triplets, quantize, transpose.
• Song timeline: clips, fades, mute, split, and automation lanes you can record from the effects pad or draw by hand.
• Sounds: sampled drum kits, synth bass and keys with presets, wavetables, sampled instruments, and a sampler you can fill from the phone's microphone.
• Mixer: volume and pan per channel and per drum voice, a 6-band EQ and a compressor with a tube mode.
• Effects pad: filter, delay, drive and reverb on an XY pad, with motion loops.

Made for playing together

• Every phone is locked to one clock, so live hits from different phones land together.
• Edits from any phone show up everywhere at once, and each player has their own undo.
• Easy mode for friends who don't produce; Advanced for free timing, velocity and every note.

Good for

• Sketching ideas with friends in the studio or on the couch.
• A live set where the crowd plays the drums.
• Showing someone how a beat is built, one track at a time.
