TYPE ANY TEXT. GET AN ACID BASSLINE.

Your words become a 303 bassline: a real 303 sound, the step pattern, and a MIDI file in the right key and tempo. Same text, same bassline, every time.

How your words become notes

• The key and tempo come from your text, so different words give a different mood.
• CAPITALS are accented notes. _ or - slide into the next note. A space is a ghost note.
• Punctuation moves the filter. Words you repeat come back like a hook.

The sound is Open303, an open-source emulation of the classic acid bass synth. Free sample packs · Kick Breeder
