How Can MIDI be Used?

In the simple, yet powerful MIDI application example below, the Yamaha QY100

Music Sequencer is used to record and play back performance data played on the EZ-

20 keyboard.

•On the EZ-20, the following channels (eight total) are enabled for MIDI recep-
tion: 1, 2, 3, 4, 5, 6, 7, 10. The MIDI transmit channels are fixed to the following
data:
Ch. 1 : Keyboard, harmony
Ch. 2 : Bass
Ch. 3 : Chord
Ch. 4–7 : Other
Ch. 10 : Rhythm
•Parts that have been recorded using the EZ-20 should also be played back from
the EZ-20. Data may not play back as expected when using other sound sources
(such as the internal sounds of the QY100).
Also, a connected sound source may sound at a different octave from that origi-
nally played on the EZ-20.
•MIDI data cannot be transmitted during song playback.
•Avoid using MIDI cables 15 meters or longer, since doing so can result in MIDI
errors.
Viewing the Notation for MIDI Channel 1
•The EZ-20 has a special function that lets you view the notes of the MIDI data
(channel 1 only) on the display.
