The short answer: Choose a synthesizer by first deciding on synthesis type (subtractive, FM, wavetable, or virtual analog), then consider polyphony, keybed feel, connectivity, and your budget; always read reviews and compare specs before buying.
The core of any synth is how it generates sound. The most common types are subtractive (e.g., Moog Subsequent 25), which filters harmonically rich waveforms; FM (like the Yamaha DX7), which uses frequency modulation for metallic and bell tones; wavetable (e.g., Waldorf Blofeld), which scans through digital waveforms; and virtual analog (like the Roland Jupiter-X), which models classic analog circuits digitally. Each has a distinct sound and workflow. If you love warm, fat basses and leads, subtractive is your friend. For digital, evolving pads, wavetable excels. FM is great for sound design enthusiasts who like complex, percussive timbres. There is no best type, only what matches your musical goals.
Polyphony matters if you play chords or use the synth with a sequencer. A monophonic synth (one note) is fine for bass lines or solos, but for pads and chord progressions you need at least 4 note polyphony. Most modern synths offer 8 to 16 voices. Some digital synths go up to 64 or 128 voices, but that often increases cost. If you layer sounds or use long releases, polyphony drops quickly. For example, a 16 voice synth playing a 4 note chord with two layers uses 8 voices. Always check the maximum polyphony and consider how you will use it. Many budget synths have 4 to 8 voices, which is enough for most beginners.
The keyboard feel is a personal choice but critical for playability. Options include: full sized semi weighted (common in workstations), synth action (lighter, springy), and weighted (like a piano). For synth leads and bass, synth action is often preferred for its fast response. Weighted keys are better if you also play piano. Also consider the number of keys: 25 keys are portable but limited, 49 keys offer two octaves plus, 61 keys is the sweet spot for most, and 88 keys are for piano players. If you already have a MIDI controller, you can get a desktop module with no keys to save space and money.
A synth should fit into your setup. Essential connections: MIDI (USB or 5 pin) for sequencing and controlling other gear; audio outputs (at least 1/4 inch jacks; stereo is better for pads); and a headphone jack. Some synths have CV/gate for modular integration. If you want to record direct to a computer, a USB audio interface built in is convenient. Also check if the synth can send and receive MIDI over USB. For live use, a sturdy metal chassis and easy to reach knobs are important. Don’t forget to see if it has an arpeggiator or sequencer, as those can add a lot of creative value.
Synthesizers range from under $200 (like the Korg Volca series) to over $3000 (flagship workstations). For a first synth, aim for $300 to $800, where you find solid options like the Arturia MicroFreak or Korg Minilogue XD. In that range you get good build quality, decent polyphony, and multiple synthesis types. Always read multiple reviews from users and trusted sites. Since we do not test products ourselves, we rely on extensive research and user feedback. Our 10 Best Synthesizers of 2026: Top Keyboards for Every Producer guide breaks down top picks by category. Avoid the trap of buying more synth than you need; start with something versatile and upgrade later.
Q: Should I buy a digital or analog synthesizer? A: Analog synths are prized for their warm, organic sound and hands on controls, but they are often more expensive and less flexible. Digital synths can emulate analog well and offer more features, polyphony, and presets. For a first synth, a digital or virtual analog synth is usually a better value. Listen to demos and decide which sound inspires you more.
Q: How many keys do I need on a synth? A: It depends on your playing style. For bass and leads, 25 keys may be enough. For chords and two handed playing, 49 or 61 keys are recommended. If you are a keyboardist used to piano, consider 61 or 88 weighted keys. Many producers use a 49 key synth and a separate MIDI controller for more range.
Q: What is the difference between a synthesizer and a workstation? A: A synthesizer focuses on sound creation and manipulation. A workstation adds built in sequencing, multitrack recording, sample playback, and often a larger keybed. Workstations are all in one production tools but can be more complex. If you want to produce entire songs without a computer, a workstation like the Korg Kronos is ideal. If you prefer a DAW and want a dedicated sound design tool, a pure synth is better.
