Description

TB-303 note is an app for quickly jotting down and managing acid bass line synth sequences — TB-303, Behringer TD-3, Roland TB-03, and more.

Perfect for those moments when:
"I want to recreate this pattern on another machine, but checking all the original settings is a hassle..."
"My hardware's memory is full, but I don't want to lose my favorite patterns."

Patterns you save can be played back instantly. Turn the built-in synth knobs to dial in that signature squelch while you shape your line.

Key Features:
- A dedicated interface: A step sequencer screen that feels just like the real hardware. Note, Down/Up, Accent, and Slide — all editable on one screen.
- Built-in preview playback: Audition your patterns instantly, even while editing, so you can hear it and tweak it on the fly.
- TB-303-style tone knobs: CUTOFF / RESO / ENV / DECAY / ACCENT — dial in the feel before you commit it to hardware.
- Dark mode support: Easy on the eyes during late-night studio sessions or on a dark club stage.
- CSV export: Export your saved patterns as CSV for easy backup and management on your computer.

Keep your acid basslines safe and ready, anytime, anywhere.
