Groove First
Clean
A free 16-step drum and bass machine in the browser - sketch a one-bar loop, hear it, and see its tempo, swing, kick and snare placement and syncopation - then have a producer keep, tweak or rebuild it for your vibe and write an AI music generator style prompt that matches the loop. MIDI and WAV export. Built on the SkillSafe skills @plyght/tonejs and @bitwize-music-studio/suno-engineer.
