Designed By Musicians

All of our engineers are musicians and they designed the R4 to empower musicians to explore big ideas. With a unique dedicated ‘bounce track’ and 32-bit float recording, the R4 is perfect for capturing your most ambitious compositions.

Record. Bounce. Repeat.

With the R4, you can record up to four tracks, mix and then bounce them to the dedicated ‘bounce track.’ This lets you free up additional tracks to keep adding layers. 

You can choose to do a ‘quick’ bounce or mix and bounce in real time.

The R4 also allows you to ‘undo’ your last bounce, if you’re not satisfied with the results.
