I purchased the Donner DEP- 20 after watching several in depth reviews on youtube. I especially enjoyed the detailed reviews by James Pavel and Jeremy See. After doing a lot of research I pulled the trigger on this instrument. For MY NEEDS, this is a 5 star instrument, your needs and mileage may be different.
I’ve been playing music for more than twenty years on several different instruments, guitar, drums, bass, keyboards, and I primarily write symphonic black metal. I have a yamaha 76 key, spring action keyboard that I wanted to replace with a full 88 key setup. To me, the main selling point of the Donner Dep-20 was the fully weighted, graded, hammer action keys…which is impossible to find elsewhere at a price tag of around $350.
This digital piano is NOT perfect, but I do give it 5 stars, because it suits MY needs. Looking at other video reviews, I noticed the sound quality of the samples were on par with standard midi. It does have 200+ different instruments, similar to midi quality. Once again, for my needs, thats not a big deal. I run the keyboard through USB MIDI into FLStudio, and play through sample libraries. So it sounds exactly like a piano (or whatever instrument I want.) No digital piano under $700-1,000 is going to have amazing quality piano sounds, it’s one of the limitations of hardware to price ratios. I already had a powerful computer, and several sample libraries (I use the Noire Piano), and I bought this piano just for the quality of the key actions.
The main selling point of this digital piano is the 88 fully weighted, graded, hammer actions keys. It doesn’t feel quite like a real acoustic piano, but it’s SIMILAR, for someone who is not a professional concert pianist. The key action is heavy like an acoustic piano, which I really enjoy. It’s very difficult to ACCIDENTALLY depress an a key. But the heavy key action affords you a lot of velocity control to really bring life to your music, just like an acoustic piano. You simply can’t get that with spring action keys on a keyboard.
The piano itself has great volume control, it can go unnecessarily loud, if you choose. I play with headphones a lot, sounds great. The build quality is decent, it’s thick, rigid plastic. Like any digital instrument, you should be careful, if you knocked it over I’m not sure what would happen to the electronics inside, but that’s not the fault of the manufacturer, that’s user error.
If you want a really in depth review, I highly, HIGHLY recommend looking for James Pavel on youtube. (Type “james pavel donner dep 20 review) he’s got a review of the piano itself, and another review comparing this product to several other digital pianos in the “under $500 range”. I’m more than a beginner (but not a professional), having played music for more than 20 years, this piano has everything I need, and nothing I don’t. As I said at the start, your needs and mileage may vary, but this digital piano delivers on every promise that was made by the manufacturer. Also like I said, if you already have a computer with a usb port, hook it up to a sample library and this instrument can easily compete with $1,000+ instruments.
I purchased this for the cheapest, fully functional, fully weighted, graded, hammer action digital piano on the market. I am extremely satisfied, the key action is great, the standard velocity curve is great. 5 stars.
