Keyboard synthesizers

Keyboard synthesizers combine sound generation and keys in one instrument, so you can start playing straight away without another controller. Here you can find analogue, digital and hybrid synthesizers, from compact models with 25 or 37 mini keys to instruments with 61 or 88 keys for live performances. Classics such as Korg microKORG, Moog Subsequent 37 and Behringer Poly D sit alongside polyphonic synthesizers such as Arturia PolyBrute, Novation Summit and Roland Juno-X. This page features only synthesizers with their own keyboard; desktop modules without keys have a separate category.

How many keys should your synthesizer have?

For basslines, solos and sound design, 25 to 37 keys are enough. A synthesizer of this size fits on your desk next to your computer and in a backpack, for example Korg Monologue or Arturia MiniFreak. Mini keys save space, but feel cramped when you play with both hands.

If you play chords with your left hand and a melody with your right, go for 49 or 61 full-size keys. A keyboard with 76 or 88 keys is useful when you also play piano parts on the same instrument, as with Yamaha CK88 or Roland Juno-D8.

Monophonic or polyphonic synthesizer?

A monophonic synthesizer plays one note at a time, making it suited to bass parts and solos. Korg Monologue is a typical example. A polyphonic synthesizer can play chords and pads: Korg Minilogue XD has 4 voices, Behringer DeepMind 6 has 6 voices and Novation Summit has 16 voices. More voices mean richer chords and fuller pads.

How does a synthesizer differ from a home keyboard?

A synthesizer is built for creating your own sounds: oscillators, filters, envelopes and modulation are within reach on the panel, and you shape the sound as you play. A home keyboard offers ready-made instrument sounds, accompaniment rhythms and speakers, so you can play songs without extra equipment. If you want an instrument for playing with accompaniment, take a look at keyboards. If you already have a keyboard, a desktop synthesizer without keys expands your sound options.
