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.

Verdict
The clearest difference is in-app purchases: 303 Note at none against Utsurohi's 1. 303 Note also leads on ads (none vs shown). Utsurohi's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 18.6). On price there is nothing between them.
