Voice List

■Maximum Polyphony

The EZ-20 has 16-note maximum polyphony. This means that it can play a maximum of up to 16 notes at once, regardless of what functions are used. Auto Accompaniment uses a number of the available notes, so when Auto Accompaniment is used the total number of available notes for playing on the keyboard is correspondingly reduced. The same applies to the Split Voice and Song functions.

• The Voice List includes MIDI program change numbers for each voice. Use these program change numbers when playing the EZ-20 via MIDI from an exter- nal device.

•Some voices may sound continuously or have a long decay after the notes have been released while the sustain pedal (footswitch) is held.

The following voices can be selected when the Voice mode is active.They can also be selected by a connected MIDI device; the corresponding bank select messages are: MSB=00H, LSB=70H.

When selecting voices via MIDI:

*The Harmony voices (#054 - #063) and Echo voices (#079 - #088) are sounded without the respective harmony and echo effects.
