FL Studio Drum Pattern

Program a basic house/techno kick pattern in FL Studio's Channel Rack.

Channel Rack Layout

The Channel Rack is a grid. Each row is one instrument:

• Left side: channel number, LED (green = unmuted), channel name (e.g. "808 Kick").
• Right side: 16 step buttons in a horizontal row. Each is a small rectangle.
  • Step 1 = leftmost button. Step 16 = rightmost.
  • Steps 1, 5, 9, 13 are evenly spaced at quarter intervals across the 16 buttons.
  • Lit (bright) = active. Dark = inactive.
• Channel rows are stacked vertically, about 20 px apart. The Kick is usually channel 1 (top row).

Procedure

1. Press F6 to open/focus Channel Rack.
2. Identify the row labeled "Kick" (or "808 Kick"). It is usually the first row.
   • If unsure, hover the channel name (left side) and check Hint Bar.
   • If still ambiguous, call extract_fl_state to identify kick-row index and active-step status.
   • Once confirmed, proceed to clicking step buttons. Do not re-verify repeatedly.
3. Click the 4 step buttons in the Kick row: step 1, step 5, step 9, step 13.
   • Once the Kick row is visible, click immediately. Do not run extra Hint Bar checks for step buttons.
   • Click each button once. Do not verify between clicks.
   • Step buttons show time elapsed in Hint Bar, not channel name. That is expected and not an error.
   • Do not spam zoom on the step row. At most one zoom is allowed before the click sequence.
   • After all 4 clicks, take one screenshot to verify all 4 are lit.
   • Prefer extract_fl_state for final verification of active steps 1/5/9/13.
   • If a click is wrong, press Cmd+Z and retry that step.
4. Press Space to start playback and verify the kick plays on every beat.
5. Press Space again to stop.
