The Yamaha DK-40C is an electronic organ featuring five keyboards: four manuals (Upper, Solo, Portamento, Lower) and one pedalboard. The instrument allows users to play melody on the upper manual, chords on the lower manual, and bass notes on the pedals simultaneously.
Key features include a variety of preset tones for upper, lower, and pedal sections, as well as specialized effects such as Touch Vibrato, Fuzz, Attack Wah-Wah, and Portamento. The manual details how to use tone levers, foot switch selectors, and expression pedals to customize the sound.

|---|---|
| Solo Manual Range | 3 octaves c~ C3 |
| Lower Manual Range | 4 octaves C~ c3 |

Only the higher note will sound because solo voices cannot produce chords.
It applies vibrato to any solo note by the lateral vibration of the hand.
No, they automatically cancel all other upper manual tone lever settings.
