Make sure all your devices are MIDI compatible. Basic live recordings cannot be transferred to a MIDI device, as MIDI assigns a unique value to each note. Digital recording programs, such as Logic, Cubase and FL Studio offer real-time MIDI sequencing, and any MIDI instrument will contain small round ports with five slots arranged in the shape of a half circle. Just look for the word "MIDI" on the device.
Connect your MIDI device using a standard five-pin MIDI cable. If connecting from a keyboard to another MIDI instrument or sequencer, no additional cables are necessary. If connecting to a computer with no MIDI port, however, you must add a MIDI-to-USB converter, such as the Edirol UM-1SX. Since you plan to transport music to the keyboard, make sure the cable is plugged in to the "MIDI In" port on your keyboard, and to the "MIDI Out" port on your other device (or converter).
Access the "setup" or "configuration" menu on your keyboard and set it to receive MIDI signals. Then test it by transmitting notes from your other device. Depending on which device you use, this can be done by pressing keys on a synthesizer, clicking buttons on a hand-held drum machine or playing a pre-recorded MIDI sequence on a computer. If your keyboard responds to the transmitted notes, then it is ready to receive input. If unresponsive, check your connections and try again.
Begin recording your musical masterpiece. Now that your devices have successfully been synced, you can send MIDI sequences directly to your keyboard and edit as necessary.
