Using the Behringer TD - 3 - LM is a breeze. First, connect it to your power source. You can use the 16 - step sequencer to create your own bass and groove patterns. Just select the track you want and start programming your notes. For different sound effects, play around with the arpeggiator and the distortion circuit. The various controls and switches give you direct access to important parameters, so you can adjust the sound in real - time. When it comes to MIDI and USB, connect it to your computer or other MIDI - enabled devices and select the appropriate MIDI channel and Voice Priority. As for maintenance, keep it in a dry and clean place. Avoid exposing it to extreme temperatures or humidity. Regularly check the connections to make sure they are secure. Also, don't use abrasive materials to clean it; a soft, dry cloth is enough.
