Using your Alesis SAMPLEPAD PRO is easy. First, connect the included correct power supply to the instrument and plug it into a power outlet. Once powered on, you can start exploring the 8 - pad percussion and sampling features. You can load your own samples or use the pre - installed ones. When you're done using it, turn off the power and unplug the supply. To maintain it, keep it in a dry and clean place. Avoid exposing it to extreme temperatures or humidity. If you need to clean it, use a soft, dry cloth. That's all there is to it, and you'll enjoy making great music with your SAMPLEPAD PRO for a long time.
