Final answer:
The MIDI specification states that the maximum length of a MIDI cable should not exceed 50 feet to ensure reliable communication and prevent signal degradation.
Step-by-step explanation:
According to the MIDI (Musical Instrument Digital Interface) specification, the maximum length of a standard MIDI cable is 50 feet (about 15 meters). This limitation is important to ensure reliable communication between MIDI-enabled devices without signal degradation. MIDI cables longer than 50 feet may result in loss of data or timing issues, therefore it is recommended to adhere to the specified maximum length to maintain the integrity of the MIDI signal.
