Using your Alesis Harmony 32 is a breeze. First, you can power it up in two ways. You can either connect it via the USB - MIDI connection or use 4 AA cell batteries (you'll need to buy the batteries separately). Once it's powered on, explore the 300 built - in tones. Simply press the keys to start making music. There's an accompaniment mode with 300 rhythms, so you can have a full - fledged band backing you up. If you want to practice quietly, plug your headphones into the 1/8” headphone jack, and the speakers will automatically mute. You can also play along with 40 demo songs or use the recording feature to create your own masterpieces. When it comes to maintenance, keep it in a dry place. Wipe it gently with a soft cloth if it gets dirty. Avoid exposing it to extreme temperatures or humidity. And if you're using the battery option, remove the batteries when you're not using the keyboard for a long time to prevent leakage.
