The Best Synthesizer Keyboards Reviews 
Let’s be honest - with vast improvements being made in technology every day, it’s becoming harder to sift through the endless varieties of synthesizer keyboards available in the market. There are simply too many choices to choose from that can make the entire experience rather overwhelming. Should you go for one with juicy fat bass options, or do you opt for better features at the expense of sound quality? What will best compliment your playing style, and should you really trust reviews on e-markets? These are probably some of the vital questions that you are mulling over while thinking of replacing your ageing instrument or while buying one for the first time.
You needn’t worry much as every musician has their own unique style. What works for some, might not work for you. Keeping this in mind, remember that the music you make has a huge role to play in this decision. If you’re into EDM and vintage synth-pop, then you are probably thinking of something that has great monophonic features. True, the classic monophonic subtractive synth you’re used to can play those juicy fat baselines and scorching leads, but these modern polyphonic synths will allow you to play chords as well. If you prefer having a music keyboard then plugging a MIDI controller with virtual plug-ins can really add that depth you have been searching for.
Although there are thousands of synth keyboard builds along with unique functions and pre-settings available in the market, we have identified 8 models that are most popular today. However, each has its own set of pros and cons that you should carefully note before swiping that card.

THow to choose a keyboard synthesizer
Whether you are a beginner or a professional, the fact that there is a perfect instrument for every type of player holds. So without further ado, let’s dive in and look at some of the key things to look out for while trying to select the best keyboard synthesizer for yourself.
- From creating single-tone sounds to ones with complex overtones and layers, it’s no surprise that a good synthesizer can change the way you create great music. Recent models of these instruments come in various complexities and can be customized to suit the needs of the musician irrespective of skill. True, these innumerable specifications might take some time getting used to, but to be honest, a good keyboard is defined by a few fixed standards, and if you have understood them, searching for a brilliant synthesizer keyboard can be a whole lot of fun.
- Most of the synthesizer keyboards that you will find in the market today use something that’s called sample-based synthesis. This means that the instrument uses sample sounds that have been pre-recorded and fed into it so the player can mix and match to create something unique. The other type of synthesizer that’s experiencing a bit of a renaissance today in the modern world is the analog type. Instead of using pre-recorded samples, they actually manipulate electrical signals to create various types of sounds. These are preferred by professionals largely because of the in-built knob-per-function control. Although these synths enjoy popularity, today’s technology has greatly improved these instruments. For example, a digital synth is becoming more popular nowadays, largely due to the fact that they can emulate sounds with greater accuracy.
- Now that you know the basic types of synths available out there, it’s time to define your own unique needs. Facts that you should consider would be to identify the style of music you play, how many keys do you prefer, and what sounds would be most important to alleviate your style. This will differ across music genres as a player of metal music will have a different playing style when compared to someone in a country-western, or a pop music band. Famous keyboard makers like Roland and Casio will have sample sound clips as online reviews to help you choose, but nowadays almost all keyboard manufacturers are providing these clips. Contrary to popular belief, today even a cheap synthesizer comes with keyboard actions and quality sound sets. So don’t be disheartened if you haven’t quite made it yet and don’t have tons of money lying around.
- The other things that you should look at should be build and weight. One of the greatest advantages of a synthesizer is the fact that you can carry it anywhere. This portability factor of a good synthesizer is often underplayed but it’s something experienced synth keyboard musicians swear by. Check the ROM capacity as well; higher it is, the better capability you will have in terms of expanding sounds. Other things like weighted keys and counts with high-polyphony, go a long way in making a synth even more versatile, playable, and powerful. Be sure to check the envelope controls as well because that will let you sustain, decay, and curate the release time of a sound. The low-frequency oscillator (LFO) is another feature you shouldn’t ignore as its application to a tone’s pitch creates a fantastic vibrato effect.
Some modern synthesizers also have extensive built-in features like chorus, delay, reverb, and many more that will help you push the sonic boundaries of what you play.
