Decide if you're going to use external instruments such as keyboards, drum machines or guitars. If using, connect the plug to MIDI out of the instrument and plug into MIDI in of MPC on channel 1.
Connect the midi out of MPC to your MIDI interface or computer sound card.
Open your music creation software and detect if your MIDI connection is working. Go to the "MIDI Options" and set the MIDI input channel to "1."
Go to the "File" menu and create a new MIDI track. Right-click the new track and click "New MIDI track" until you get 5 to 10 tracks.
Highlight the "Record" option for track 1 and press buttons on your MPC to see if the sound signal registers.
Press the "Record" button on track 1 and either play your samples or import your already composed beat. Select a new track and record every instrument you wish to use.
Save the song on your music creation software as well as on the MPC.
