Fast answer

Set CLOCK IN to OFF if you only want the DAW’s drum notes to play the SR-16 kit. Keep DRUM IN enabled for those notes.

Try these checks

  1. Press MIDI SETUP and go to page 5, CLOCK IN.
  2. Set CLOCK IN to OFF for a note-triggered drum-module setup.
  3. Check DRUM IN on page 2 is ON V1 or ON V2, then play the DAW’s drum part again.

Diagnose it

Do you want the SR-16’s own pattern sequencer to follow the DAW?

Yes: Keep external clock enabled and use the pattern workflow instead.

No: Use CLOCK IN OFF and send the drum notes you want.

What should happen

Incoming drum notes can play the kit without clock starting an unwanted pattern.

Why this happens

Alesis specifically recommends CLOCK IN OFF for expander-module use.

If it still doesn’t work
