@ MIPi Out Terminal
Connect DG-20 to other MIDI
instruments or devices. MIDI
messages transmitted through
this output. (Refer to page 8 for
further information on MIDI).
1. When a string is played, the
string's vibration is sensed by a
built-in sensor and the selected
tone is output through the built-in
speaker.
2. The digital guitar features
switches which are actually built-in
to the fingerboard, behind each
fret. If your finger(s) is not properly
centered over the strings you
depress, neighboring strings may
sound (even though you haven't
depressed neighboring strings), as
the switches may be activated.
No sound is output if strings
are played too softly.
There are two different basic types
of preset sounds built-in to the
DG-20—sounds which decay, such
as the acoustic guitar tone, and
sounds which are sustained, such
as the jazz organ tone. Sustained
sounds may be cut off by using
the mute key, or by releasing the
fretboard (which turns OFF the
built-in sensor switch).
