Hardware synthesizers have been around for a long time, but only during the 1960s, they were often heard in mainstream music. In the 70s and 80s, they made it to new genres at that time, such as disco, ambient, and new wave. As time went by, the invention of computers and production software later affected how manufacturers would develop synthesizers. With electronic music being prominent in both pop and underground music, there has been a surge of manufacturers developing affordable synthesizers that are great for live performances and studio use.
This guide presents a range of synthesizers for those who are interested in choosing their first hardware synth and for musicians who are looking for a unit to add to their collection.

The Best Analog Keyboard Synths
The Arturia MicroBrute is an even smaller version of the Minibrute with updated features including a new sub-oscillator, Mod Matrix and step sequencer. Its redesigned sub-oscillator (Overtone) provides additional harmonics that gives a classic sounding lead and a fatter bass. Its Mod Matrix allows you to reroute/patch from three modulation sources- ENV, LFO and Keyboard CV (on the rear panel)- to six modulation destinations on the panel itself. Similar to its predecessor, it has a single voltage-control oscillator with three-waveforms, and other modifiers (ultrasaw, pulse width, metalizer) for a customizable sound. It also incorporates a Steiner-Parker filter that was used on a Synthacon synthesizer back in the 1970’s.
- Polyphony: Monophonic
- Keys: 25-note mini-key keyboard
- Oscillator: 1 x Analog Voltage Controlled Oscillator
- Filter: Steiner-Parker Multimode filter

Both experts and users were more than satisfied with its responsive keyboard and retro design. Its rigid knobs and controls are laid out in a sensible way that gives users an instant access to the parameters. In his Sound on Sound review, Paul Nagle mentioned the stored factory presets offered "countless (at least I didn't count them) solo patches of the in-your-face and searing type, and rather fewer of the flowery, new age sort. Pads and strings are lush and tasty, and as for bass, those sub-oscillators could add rumbling nuances to any track." The unit's four LFOs provided various modulation options to its two stable sounding oscillators, letting musicians create complex sounds and store their own personalized patches.
Some users pointed out its lack of audio inputs, though a MIDI Input and a Poly Chain lets users connect to other Dave Smith Instruments and MIDI equipment for layering sounds. Arpeggiator and sequencer editing sections aren't present on the front panel itself, but it can be edited via editing software.
For a reasonable price, this is an exceptional choice if you are looking for a unit with massive signal and modulation routing capabilities.

Things to Consider When Buying a Synthesizer
Polyphony / Number of Voices
Polyphony is defined by the number of multiple notes that can be played at once. There are two main types: monophonic and polyphonic. Monophonic synths are capable of playing one note at a time. A number synth enthusiasts tend to favor monophonic synthesizer due to their rich, full and pronounced sound compared to polyphonic synths. Polyphonic synths, on the other hand, let you play multiple notes all at once. Although they sometimes sound a bit thinner, they tend to have the essential options and are capable of letting you play leads and chords, if you plan to make the synth your main instrument. Both have affordable options to choose from.
Size and Portability
Choosing the size depends on where you will plan to use your unit. A small and compact synthesizer with less than 49 keys is recommended if you have limited space. It's also easier to carry around for live performance purposes or if you plan to jam with others in their own domain.
Controls and Interface
Synthesizers come with different interfaces and controls yet they all function the same way following the basic signal path: oscillator, filter, then an amplifier. Most synthesizers have the basic waveforms shape for built-in LFOs, envelope generator with ADSR sliders, and at least one control for effects used to enhance the sound. Some synthesizers with more than one modulator have a Mod Matrix, which is a grid that's used to intuitively route modulation sources easily to their destinations (LFO to filter cutoff, mod envelope to pitch, etc). It's highly suggested to get a synthesizer that gives you a straightforward layout of knobs, sliders and buttons without needing to look through menus, or having to do multiple combinations of buttons.
A common feature found in synthesizers includes a built-in sequencer. This is useful if you want to write and save melodies or bass lines in the synthesizer's memory bank, and loop them while tweaking other parameters. Some synthesizers also have stored percussion and drum sequencers for creating beats.
A lot of synthesizers on the market have numerous functions that may factor in your sound preference and productivity. If you need a full polyphonic synth without breaking the bank, digital synthesizers are the best option. Monophonic analog synthesizers are also great entry level and budget options if you are new to synthesis. Overall, it depends on the price to performance ratio in order to prioritize the features you need when looking for a synthesizer.
