AcidLines is a grid sequencer which uses the Web MIDI protocol to control an external synthesizer device or software plugin. It is geared specificallt towards 303 clones such as the TB-03 and TD-3, but is usable with any synthesizer that can accept MIDI input.

Server not yet online, coming soon! (削除) Try AcidLines at acid.musictools.live. (削除ここまで)

Features planned for future versions of AcidLines:

• Acid smiley for favicon
• Ability to queue multiple patterns into a track
• Online sharing and browsing of patterns
• Built-in acid synth to preview patterns or tinker without a hardware 303-clone

I would like to find collaborators to help me bring this project to its full potential. If you are interested, please reach out.
