What is Live Rewind?
Live Rewind is an always-on buffer in Play mode. From the moment you start playing, Tiny Instrument silently records a rolling window of up to 2 minutes of your input. You never need to arm a recording — just play.
Once you've played at least one note, a Rewind button appears in the Play mode toolbar.

Play modeTap Rewind to act on your idea
Tap the Rewind button in the toolbar. A menu appears showing how much was captured — for example "Last 30s captured" — with three options:
• Play — hear back exactly what you just played
• Save to Compose — convert the capture to a composition
• Discard — clear the buffer and start fresh
Set the capture duration
The capture duration controls how many seconds the Rewind menu plays back or saves. Choose from four fixed options: Last 10 seconds, Last 30 seconds, Last 1 minute, Last 2 minutes.
Set this before you start playing so the right amount is ready when inspiration strikes. A shorter window gives you just the last phrase; the full 2 minutes captures a longer improvised section.
Save to Compose
Choose Save to Compose from the Rewind menu to turn the captured MIDI input into a composition. Tiny Instrument converts your playing into a composition track, preserving the exact timing and notes. The composition opens automatically in Compose so you can keep building on the idea.

ComposeTips for capturing more ideas
A few habits that make Live Rewind more useful:
• Set the duration before playing, not after. The menu shows the pre-set window — you can't trim after the fact.
• Loop a backing progression while you improvise — it gives context and makes the saved composition more musical.
• Rewind immediately after a phrase that surprised you. The best ideas often come from mistakes.
