8 Best Chord Synths for Songwriters and Beginners

The best chord synths right now are the Orchid ($649) for writing songs, the Suzuki Omnichord OM-108 (about $900 to $1,000) for the classic strummed sound, and the HiChord ($320) or the Minichord ($174.99) if you want one small enough to carry. Each plays a whole chord from one button, so you can accompany yourself or sketch a progression before you have learned a chord shape.

Below are eight picks: seven pieces of hardware and one iPhone app. We make the app, Gelato Chord, so it is marked (ours). Prices are US prices checked in September 2026, when the Orchid was sold out between batches.

What is a chord synthesizer?

A chord synthesizer is a synthesizer built so that one button or key plays a full chord, voiced for you and usually named on the panel. On a piano you find C, E and G with three fingers; on a chord synth you press the button marked C.

The instruments below pick chords in one of three ways:

• Seven buttons for one key: the buttons play the diatonic chords of the key you choose, meaning the seven chords built only from that key’s scale. In C major those are C, Dm, Em, F, G, Am and Bdim (our chords in C major page spells out every note). Nothing clashes, which makes this the easiest layout for a beginner. The HiChord works this way.
• Any root plus a chord type: you choose the root note, then major, minor, 7th and so on. A chord from outside the key, such as Fm in a C major song, is one press away. The Omnichord, the Orchid and the Minichord work this way.
• Chord sets and suggestions: the instrument loads a set of chords onto its keys or pads, or proposes which chord could come next. The Roland J-6, the Chordcat and the Launchkey’s Chord Map mode work this way.

The Omnichord and the Minichord also have a strum plate, a touch strip that plays the notes of the chord you hold as you brush a finger along it, so one sweep sounds like a harp. Suzuki’s Omnichord, first sold in 1981, made the idea famous.

Best chord synths for songwriters and producers

These four live on a desk or a lap. Only the first two have speakers.

1. Orchid ORC-1 (Telepathic Instruments). Paid, $649, standalone hardware, sold direct in limited batches.

   Built for writing songs. A one-octave keyboard sets the root, four chord-type buttons pick major, minor, diminished or suspended, and four more add a 6th, minor 7th, major 7th or 9th, in any combination. Minor plus the minor 7th button on the A key gives Am7 (A, C, E, G), and the two voicing dials walk that chord up or down the keyboard through its inversions (C, E, G, A, then E, G, A, C). Key Mode makes every key on the keyboard play a chord that fits the key you set. Three engines (subtractive, FM and a vintage electric piano) supply 70 preset sounds, with Strum, Harp, Arpeggiator and Pattern modes, a looper with overdub and undo, 20 drum beats and two speakers. Tame Impala’s Kevin Parker co-founded the company and designed the sounds.

2. Omnichord OM-108 (Suzuki). Paid, about $900 to $1,000 new at US dealers; batteries and the power adapter are sold separately.

   Suzuki’s electronic autoharp, back in production. Press a chord button, brush the wide strum plate, and you get the shimmering harp sweep the Omnichord is known for. The OM-108 plays 108 chords, adding sus4 and add9 to the classic set, and its omni1 and omni2 tones use analog circuitry to recreate the sound of the 1984 OM-84. Eight more tones (harp, celeste, piano, guitar, FM piano, organ, vibes and banjo) and 10 rhythm patterns sit alongside, with a built-in speaker, power from eight AA batteries or the adapter, and MIDI out for chords, strums and drums.

3. Chordcat (AlphaTheta). Paid, $329 from the maker’s US store, standalone hardware.

   A small groovebox (247 by 111 mm, 400 g) that suggests chords. Set a key and scale, switch to Chord Cruiser mode, and it offers several chords that fit; assign the one you like to a key and it suggests what could follow, drawing on up to 110,000 combinations. An 8-track sequencer, 145 sounds and 16 drum kits let a progression grow into a full beat. Digital DJ Tips found the sounds fine for getting ideas down but no replacement for your main instruments. There is no speaker, and six AA batteries last about five hours. It suits producers who get stuck on the second chord.

4. Launchkey Mini MK4 (Novation). Paid, $129.99 for 25 keys or $159.99 for 37; needs a computer or another synth.

   If you already make music on a laptop, this is the cheapest hardware on the list. It makes no sound of its own: plug it into a computer (it comes with Novation Play, a software instrument with more than 80 sounds), or into a hardware synth through its 3.5 mm MIDI out. Choose one of 30 scales and Chord Map puts eight chords that fit it on the left-hand pads. The Adventure and Explore knobs flip through 40 banks of eight chords, and Spread changes how widely each chord is voiced. Fixed Chord mode maps one chord shape to every key, so a single finger plays a full chord from any root.

Pocket and mini chord synths

All three run on rechargeable batteries, and only the HiChord has a speaker.

5. HiChord (Pocket Audio). Paid, $320 on pre-order; the maker says the silver and black aluminum editions ship in mid-October.

   The friendliest start for a total beginner. Seven buttons play the diatonic chords of your key, so in G major they give you G, Am, Bm, C, D, Em and F#dim. Hold a button and push the joystick to recolor the chord: in C major, hold C and push up for Cm, right for Cmaj7 or down for Csus4. The aluminum case measures 100 by 71 mm and holds more than 30 instruments, a six-track looper, a drum machine, a microphone for sampling and a vocoder, a mono speaker and a rechargeable battery.

6. Roland J-6 (Roland). Paid, about $270 new.

   A small box (188 by 106 mm, 295 g) with a four-voice engine modeled on the JUNO-60 and 64 preset sounds. Choose one of 100 chord sets and each key of its one-octave keyboard plays a chord from that set. Set 7, Trad Maj, puts C, Dm, Em, F, G, Am and Bdim on the white keys; the pop and jazz sets swap in 7ths, 9ths and slash chords. Nine styles with 12 variations each turn a held chord into arpeggios and rhythms, and the sequencer stores 64 patterns of up to 64 steps. Four voices means four-note chords at most. There is no speaker, and the battery lasts about 4.5 hours.

7. Minichord (Benjamin Poilve, sold by Seeed Studio). Paid, $174.99, open-source hardware.

   The cheapest way to strum. It borrows the Omnichord layout: 21 buttons in seven columns (F, C, G, D, A, E, B) with rows for major, minor and 7th chords, a sharp button that raises any chord a semitone, and a 12-section harp strip you can strum or tap note by note. Combine buttons in one column for more chord types: the C major and C 7th buttons together give Cmaj7, and major plus minor gives Cdim. It has no speaker (plugging in headphones is what switches it on), plays for about 7 hours per charge, and works as a USB MIDI instrument.

Chord synth apps: the free way to try it

Before spending anything on hardware, open our free online chord player in a browser, pick G major and play G, D, Em and C over and over, the 1-5-6-4 progression behind a long list of pop songs. If you are still playing ten minutes later, chord buttons suit you.

8. Gelato Chord (ours) (Gelato Audio). Free with one $4.99 in-app purchase, iPhone.

   A pocket chord instrument built in the spirit of the HiChord and the Omnichord. Its seven keys carry the I to vii° chords of one key, each labeled with its name, and pressing nearer the top of a key plays it louder. Beside them, a melody plate lays out the key’s scale as twelve strings with the held chord’s notes lit up. A wheel labeled VOICING pushes the held chord richer with 7ths and 9ths, or opens it toward sus sounds, without changing which chord it is. The free version is the whole instrument in Play mode with three sounds (Grand Piano, Rhodes and Saw); the $4.99 purchase adds Strum, Lead, Arp and Repeat modes, a loop recorder and all 59 sounds. As on the HiChord, you play within one key at a time.

HiChord vs Omnichord vs Orchid vs Minichord

HiChord vs Omnichord. The HiChord works from the seven chords of one key and fits in a pocket. The Omnichord gives you every root and a real strum plate, and it lives on your lap. For catching ideas on a bus, pick the HiChord. For singing over a strummed accompaniment at home, pick the Omnichord, at roughly three times the price.

Omnichord vs Orchid. Both build any chord from any root. On the Orchid, the looper holds a progression while the voicing dials try it in different inversions, which makes it the better sketchpad for a song. The Omnichord has the strum plate you play with your fingers and the analog omni tones. New, the Orchid costs about $250 to $350 less, when it is in stock.

Omnichord vs Minichord. The Minichord copies the Omnichord’s button rows and strum strip for about a fifth of the price. You give up the built-in speaker and rhythm section, and you gain USB MIDI and firmware you are free to change.

One more route to a real Suzuki is the QChord, the company’s 1999 redesign of the Omnichord, which kept the chord buttons and strum plate and added a slot for song cartridges. Suzuki no longer makes it, so you will only find it used, and in September 2026 used ones were listed for about $460 to $690 on Reverb. Ask the seller for a video of the strum plate responding from end to end before you pay. For more strummed options, see our list of Omnichord alternatives that cost less.
