## What is SUS4 Loop Builder?

Record a part, loop it, and stack the next one on top.
Up to eight tracks, each with a level control, so the idea sounds like a song before you leave the room.
Fully on-device: no cloud, no account.

Start with a chord loop, add a bass line, then a melody. Undo the last layer if it was wrong. When it works, export the mixdown as an audio file.

• Up to 8 loop tracks, with level and mute per track
• Undo the last layer
• Export the mixdown as an audio file
• A library of saved loop sessions

For guitarists and singers building song ideas, beatboxers, and anyone who uses a loop pedal on stage and wants one in their pocket.

Pro, or SUS4 All-Access across the whole range, adds reverb, delay and 3-band EQ on each layer, stem export (every track as a separate file) and unlimited saved loops.

Made in the UK by working musicians.
