Connect the e-drums to your computer or hardware MIDI workstation using the MIDI/USB cable and the MIDI-out/in ports on the e-drums and workstation. This connection will allow data to move between the e-drums and the device storing the triggered sounds.
Open your digital audio workstation or preferred hardware device and access the "I/O" settings menu. Select your e-drums as the preferred MIDI input device within this control panel. Test the connection by striking one of your e-drum pads. If your devices are configured properly, your workstation should display evidence of MIDI activation, such as a raise in volume level for the MIDI track or, if your speakers are connected, a sound.
Select the sounds you would like to assign to each of the e-drum pads within the synthesizer or sampler sound bank you are using. After determining which sounds you will implement, assign them to your preferred place on the e-drum by inputting the number of the specific MIDI trigger (in this case, drum pad) into the synthesizer or sampler's control settings.
Test your configuration by hitting each pad on the e-drums. If you have made the appropriate connections and successfully assigned the sounds, each drum should play your preferred tone when struck.
