Compare two complete sampler ideas with A/B

A/B keeps two complete versions of your sound, Chops and effects included. Your edits go into the slot that is active. To compare versions of just one Chop, use a Branch instead.

Updated 7 November 2026 · S9 Audio

Use A/B when you’re asking whether a different overall treatment works better in the track. Play the same phrase each time.

Step by step

  1. Pick your reference

    Play a short phrase and choose the slot you want to keep as the reference.

  2. Copy to the other slot

    Use the arrow menu to copy your sound across, so both slots start the same. Check the direction before you copy.

  3. Edit the other slot

    Switch to it and make your changes. Check which letter is active before each edit.

  4. Compare

    Switch A and B on the same notes, in the track and solo. Match Output so loudness doesn’t decide for you.

Good to know

Keep the winner

Switch back to the slot you prefer, then save the sound. Use a Portable Pack if the audio needs to travel.

New audio starts over

Replacing the sample starts a fresh A/B. Undo can bring back the earlier sound.
