It's possible to use two pads connected to the trigger input on the SPD-S. For this application, you'll need a "Stereo Insert Cable" (Roland PSC-31L), and you'll need to change the Trigger Input mode so that the SPD-S knows you have two pads connected to it. Use the following Steps to change the Trigger Input Mode in the SPD-S:
1. Press SETUP.
2. Press PAGE right until TRIGGER INPUT appears in the display.
3. Press ENTER.
4. Press the (-) button to select "TRIGx2."
5. Press EXIT when you're finished.
