🧱 SONG BUILDER

Drag a pattern letter from the palette onto a track to place it. Drag a placed block to move it anywhere on the timeline — even to a different track. Click a placed block to remove it. Each cell is one loop through that pattern (16 steps). Stack patterns on different tracks at the same position to layer them — they'll play together, mixed, like a real DAW. Use + ADD TRACK to add a new lane, and name/mute/delete tracks from the header on the left of each row. This plays for real using the exact same engine as the drum machine page. Use the Song Library below to save named arrangements and switch between them. Save Arrangement (bottom bar) sets whichever arrangement is currently on the grid as the active one the drum machine page plays. The 🎯 follow button auto-scrolls to the playhead while playing — scroll manually to release it, click it again to re-engage. Right-click a placed block for duplicate/mute/delete/split options — split mutes off a half or quarter of that block so only part of the pattern plays. ↶ UNDO (or Ctrl/Cmd+Z) steps back through changes. Click or drag anywhere on the timeline to drop a green cue marker — press ▶ play and it starts from there, or drag it while a song is already playing to jump straight to that point, just like scrubbing in a DAW.
