303 Day is back

Worldwide, the TB 303 community celebrates the device that left a mark on electronic music. Create a track in the new Studio with a clear Bassline-3 lead for a chance to win a Behringer TD-3-MO SR.

Produce your track here: https://beta.audiotool.com/studio

How this contest works

• Produce your track in the new Studio

• Export it using DOWNLOAD
• Upload it to the old Studio as a sample
• Publish it as a track
• Submit it by March 20, 2026 → https://www.audiotool.com/contest/303_day_create_a_bassline-3_track_in_the_new_studio
• Invite a-records to the project in the new Studio and post the link in the description of the submitted track.

Good news: If programming the 303 felt complex, the new Studio lets you play the device directly via the Note Region.

We are curious to hear what you make.

Since we’re in Beta: in case you run into a bug, please let us know. We’re continuously improving: https://tally.so/r/mD87Pp

With the next update, the remaining projects from the old Audiotool platform will be synced to the beta environment. This means that the last batch of legacy tracks will soon be available directly in beta where they can be opened and edited just like any other project.

The update is currently planned for next Monday, March 23.

As part of this process, projects that exist only in beta will be removed. If you have beta-only projects, please make sure to export and download your WAV files beforehand so you don’t lose your work.

If you’d like, you can also publish your WAV exports on Audiotool so we can add them to the album NEW STUDIO JAMS

By then, the 303 Contest entries will have already been exported and archived by us.

In the meantime, feel free to continue exploring and creating in the new Studio: https://beta.audiotool.com/
