Voice Studio

Your voice is the controller. Use headphones — speakers feed back into the mic.
The meter above shows what the mic hears; the note is your detected pitch.
First time here? Try this: hit Enable Mic, turn on Beatbox→Drums, and say "boots and cats, boots and cats". Yes, really.
Sing → Notes
Enable the mic (top right)
Click an instrument tile below — that's your voice now
Hum or sing — hear it played instantly
Arm ● Rec — your melody becomes a loop (Click on = quantized)
Beatbox → Drums
Enable the mic
Focus the 808 Kit tile
"b" = kick · "ts" = hat · "k / pf" = snare
Arm ● Rec, beatbox a bar — edit it in the Steps grid after
Auto-Tune
Enable the mic
Sing — your pitch hard-snaps to the nearest note
Hit ⏺ Mix to record your tuned takes
Vocoder
Enable the mic
Talk — instant robot voice
Hold keys on the keybed to pitch it into melody
Arrange
Paint where each loop plays — one column is one bar of your master loop. Turn the arrangement on,
hit ▶ Loop, and the song follows the chart. The keybed stays live below so you can play over it.
