Operating Instructions
Keys and Touch Response
The DEP-10 features 88 semi-weighted keys, designed to provide a realistic piano feel. These keys offer a sensitive touch response, allowing for expressive playing dynamics. The semi-weighted action provides a balance between the lightness of a synthesizer and the resistance of a fully weighted acoustic piano, suitable for various playing styles.

Tones and Polyphony
The digital piano offers 8 distinct instrument tones, including Acoustic Piano, Electric Grand Piano, Church Organ, and more. You can switch between these tones using the dedicated controls on the panel. The 128-note polyphony ensures that notes do not cut off prematurely, even when playing complex pieces with sustain pedal usage, providing a rich and full sound.
The Dual Tone Setting Function allows you to layer two different tones simultaneously, creating a richer and more complex sound. Refer to the control panel for tone selection buttons.

Sound Quality and Connectivity
Equipped with two built-in 25W speakers, the DEP-10 delivers clear and powerful audio. The integrated triple pedals (sustain, sostenuto, soft) provide full expressive control. The piano also includes audio input and output jacks for connecting external devices or sound systems, and an MP3 player for playback.

Versatile Features
- Metronome: Control your rhythm with different metronome beats (e.g., 1/4, 2/4, 3/4, 4/4).
- Effects: Apply various effects such as trill, suspension, and DSP to enhance your sound.
- Recording Mode: Record and arrange your music directly on the piano. This feature allows for practice and composition.
- Transposition: Adjust the pitch of the entire keyboard up or down.
Headset Mode
For private practice, the DEP-10 supports headset mode. Simply plug your headphones into one of the two 6.35mm headphone jacks located on the piano. This allows you to practice quietly without disturbing others.

Donner Music App Integration
The Donner DEP-10 is compatible with the Donner Music App, offering free online courses and additional learning resources. Connect your piano to a tablet or smartphone via USB to access these educational features and enhance your learning experience.
