How we ranked these synthesizers
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.
- Keys weight 2
- Max polyphony weight 3
- Analog engine weight 2
- Presets / patterns weight 1
- USB-MIDI weight 1
Buying advice: 37 key synthesizer
Count voices before you choose
Voice count decides how many notes sound at once. The MiniNova plays 18 voices, the MiniFreak plays 6 voices, and the minilogue plays 4 voices. If you hold long chords with many notes, the higher voice count covers them; if you play one line at a time, the lower count covers it.
Decide analog, digital or hybrid sound
Sound engines decide the palette. The minilogue runs a true analog engine, the MiniNova runs analog modeling, and the JD-XI pairs analog and digital engines, while the MiniFreak pairs digital and analog engines in a hybrid design. A vocoder appears on the MiniNova and the JD-XI, each with a gooseneck mic in the box.
Check presets, sequencer and weight
Presets decide how fast you find a sound. The MiniNova holds 256 presets and saves 128 more, and the minilogue holds 200 presets. For patterns, the minilogue runs a 16-step sequencer and the JD-XI runs a four-track pattern sequencer. Weight matters if the synth moves: the JD-XI weighs 4.1 lb, the minilogue weighs 5 lb, the MiniNova weighs 6 lb and the MiniFreak weighs 6.5 lb.
