About MIDI
MIDI (Musical Instrument Digital Interface) is a worldwide standard that is built into many electronic musical instruments and other digital music related devices, allowing them to be connected and “communicate” with each other.
For two MIDI instruments to communicate, they must be connected by MIDI cables. In a basic example, the MIDI IN and MIDI OUT terminals of the PortaTone could be connected to the MIDI OUT and MIDI IN terminals of a se- quencer, allowing you to record and play back performance data from the PortaTone.
The instruments communicate with each other by sending “messages” or MIDI data. The sending instrument usually assigns the data to one of sixteen MIDI channels, then transmits it over the MIDI cable. The cable itself, however, is not divided up into sixteen channels. Just as with a television set that receives programs on different channels, it is up to the receiving instrument to “tune into” the proper MIDI channel. If the sending and receiving channels on the respective instruments do not match, the receiving instrument may not understand or respond to the one sending.
How Can MIDI be Used?

Before actually recording to the sequencer, press the ACMP button once or twice to make sure that the current settings are sent.

•Parts that have been recorded using the PortaTone should also be played back from the PortaTone. Data may not play back as expected when using other sound sources (such as the internal sounds of the
•MIDI data cannot be transmitted during song playback.
•Avoid using MIDI cables 15 meters or longer, since doing so can result in MIDI errors.
