The Donner DEP-20 is an 88-key fully-weighted keyboard for beginners and intermediate players designed to helps you gain plenty of dynamic control and expression learning piano or performing at a small stage.

The Donner DEP-20 comes with a classic sound engine with digital technology making it perfectly resemble the classical acoustic piano.

The keyboard is thus characterized by its ability to produce a deeper and richer sound, and is suited for professional mixing and recording since it has two hundred and thirty-eight in-built sounds including basses, organs, percussion, and a host of wind instruments. The digital piano is designed to serve musicians playing in diverse cultures, genres, and styles.

The keyboard also has one hundred and twenty-eight sounds and two hundred internal rhythms which are absolutely essential in the technique of accompaniment. These rhythms range from Country, Jazz, Pop, Reggae, Latino, and more.

The Donner DEP-20 is an 88-key fully weighted keyboard that gives 238 tones including popular ones such as drums, bass, and ukulele, and a further 128 polyphonic tones. The tones give you a wide choice of voices and instruments that you need for your music lessons, recording, or stage performance.

The Donner DEP-20 electric piano comes with a maximum polyphony of 128 notes. The extended polyphony of 128 notes combined with 238 tones ensures that you can expand your playing to the max. You’ll always have ready tones whenever the situation calls for it.

This is an impressive polyphony range for a digital piano of the Donner DEP-20 range. In fact, most portable digital pianos normally have a polyphony of between 64 and 192, with 256 polyphony pianos being in the high-end pricier range.

One important thing to understand about digital piano polyphony is that a piano with a larger amount of polyphony helps you to play extensive sounds for longer without reaching a polyphony cap or limit.

All modern pianos normally use stereo samples that need two notes for every key you play, which increases the need for more polyphony notes. The piano also requires extra polyphony for the backing track that you play when performing or recording music.

If the piano has a low number of polyphony notes, you’ll quickly reach the limit of your piano’s polyphony and start losing the notes you had earlier played to free up more memory for the notes you are about to play. The results of the drop in notes will have a negative impact on your music.

A piano with a good number of polyphony notes such as the Donner DEP-20 128 notes will ensure that you maintain the great quality of your sounds even after you play a lot of notes at the same time. It allows you to play, record, and run your stage performances without hitting the polyphony limit.


One thing you’ll notice about the Donner DEP-20 is that is its speakers are quite loud. The digital electric piano comes with a pair of 25W speakers that fire both upwards and downwards towards the floor to give you better and more pronounced spatial sound separation. We also noticed that the speakers tend to lose a little bit of clarity when played too loud.

You’ll also be glad to know that the Donner DEP-20 comes with two ¼ inch headphones jack at the front. With a good set of headphones, you’ll get decent sound quality and volume for your solo practice sessions. The piano also features another ¼ inch audio output port at the back that you can use to connect to your amplifier for better-controlled sound output.

Overall, the Donner DEP-20 has impressive speakers for a digital piano in its price range. It is loud enough for any small room, bar, studio, and small public performance and works with any kind of power supply. The output comes out clearly without any distortions or crackling.


The Donner DEP-20 comes with more extra features only found in other higher-end pricier pianos.

Some of the performance-enhancing features of the Donner DEP-20 include the following:


One of the coolest features of the Donner DEP-20 is its chord and multi-function settings. The digital piano comes with automatic chord settings which allow you to play a specific chord simply by playing a single note.

You can place the setting anywhere on the keyboard’s notes where you want the chord played so that when you play the note the keyboard will automatically fill the note further to play your chosen chord.

The Dual Tone is another handy feature of the Donner DEP-20 digital piano. This feature combines any two chosen sounds together to create another unique sound. With the keyboard’s 238 tones, you have an endless choice of combinations to play.

The digital piano also provides you with a Double Tone setting feature that practically divides the keyboard into two distinctly unique sounds.

The setting is quite useful when you are doing a duet with another person. You can, for instance, set the right half of your keyboard to a piano while the left plays bass or another voice to create a perfect duet.

Another great feature of the keyboard is its Multifunction Setting which provides you with two chord modes namely Single Finger Chord and Multi Finger Chord.
