The Yamaha MODX6+, Yamaha MODX7+ and Yamaha MODX8+ have the same sound engine, the same 2,227 Performances, the same touchscreen and the same connections. The only real difference is the keyboard: 61 semi-weighted keys, 76 semi-weighted keys, or 88 keys with Yamaha's GHS weighted action. So the question is which keyboard you play best on, and how much size and weight you can live with.
Quick verdict: buy the MODX6+ (₹1,59,990) if you play synth parts, pads and one-handed leads, or need a board that fits a small desk and a car boot. Buy the MODX7+ (₹1,68,310) if you play two-handed parts, split keyboards on stage or want extra range for ₹8,320 more. Buy the MODX8+ (₹1,89,790) if piano is your main instrument and you want weighted keys, and you can handle a 13.8 kg board.

All three models: AWM2 and FM-X engines with 128 notes of polyphony each, 5.67 GB preset waveforms (in 16-bit linear format), 1.75 GB user flash memory, 7 inch colour touchscreen, 4-in/10-out USB audio interface, initial touch (velocity) and no aftertouch.
What is the same on every MODX+
Because the three models share everything except the keyboard and chassis, it makes sense to understand the common platform first.
Sound engine: AWM2 and FM-X
Yamaha calls the MODX+ engine Motion Control Synthesis, the same system used in the flagship MONTAGE. It combines two tone generators. AWM2 is Yamaha's sample-based engine with up to 8 Elements per Part, covering acoustic pianos, strings, brass, drums and sampled synths. FM-X is an 8-operator FM engine with 88 algorithms for electric pianos, basses, bells and modern synth sounds. Each engine has 128 notes of polyphony, so layered pads and sustained piano parts do not run out of notes easily.
The instrument is 16-part multitimbral and includes 2,227 Performances. There is 1.75 GB of flash memory for your own samples and third party libraries, and Yamaha says the MODX+ can load MOTIF XS/XF Voices and Performances. Yamaha also offers a free Bösendorfer Imperial piano download for registered MODX+ owners.
Effects
The effect system has 12 reverb types, 88 variation types, insertion effects with 88 types, 26 master effect types and a five-band master EQ. In use, that covers everything from hall reverbs for ballads to sidechain compression, vocoder and amp simulation for electronic and rock sounds.
Performance controls
Every model has pitch bend and modulation wheels, four sliders, four knobs, the Super Knob and a data dial beside the 7 inch touchscreen. Yamaha says the Super Knob can move up to 128 parameters at once, and it can be controlled from an FC7 foot controller. Eight Scene buttons store snapshots of arpeggio, Motion Sequence and mix settings. The Live Set function lets you arrange up to 2,048 user Performances in set order, and Seamless Sound Switching keeps notes from cutting off when you change sounds, for Performances of up to four Parts.
Arpeggios, rhythm patterns and sequencing
There are 10,239 preset arpeggio types, with up to 8 Parts running arpeggios at once. The Rhythm Pattern button adds drum patterns quickly, which helps when writing songs or practising without a drummer. The built-in recorder handles 128 Songs and 128 Patterns with 16 tracks each at 480 ppq resolution.
Connections
The rear panel has stereo outputs, a headphone jack, stereo A/D inputs, MIDI in and out, two foot controller jacks, sustain and assignable footswitch jacks, USB to Host and USB to Device. The A/D inputs accept a microphone, synth or other line source, and Yamaha notes that passive guitar pickups should go through an effects unit first.
USB to Host carries MIDI and audio. The built-in USB audio interface sends 10 channels and receives 4 channels at 44.1 kHz, so you can record the MODX+ into a DAW with one cable and no separate interface. Yamaha says the connections are compatible with iOS devices. MODX+ Connect runs as a VST3 or AU plug-in, or standalone, for saving and editing MODX+ settings from your computer.
Yamaha MODX6+: 61 keys, the most portable
The MODX6+ is 937 mm wide and weighs 6.6 kg. That is small enough for a typical study table and light enough to carry in a gig bag on a two-wheeler or in a car boot without a second person.
Sixty-one keys cover five octaves, which is plenty for synth leads, basslines, pads and most film and pop keyboard parts. Octave buttons shift the range when you need to go higher or lower. The semi-weighted action is quick for fast synth lines and organ-style playing.
Who it suits: producers who want a hardware synth at the centre of a home studio, keyboard players in bands who mainly cover synth and pad parts, and musicians who travel to gigs regularly. It is also the right choice if your desk sits against a wall in a small bedroom studio.
Where it falls short: two-handed piano parts with a wide left hand, and keyboard splits where you want bass in the left hand and a full lead range in the right.
Yamaha MODX7+: 76 keys for split playing
The MODX7+ adds 15 keys for ₹8,320 more. It is 1,144 mm wide and weighs 7.4 kg, so it is only 0.8 kg heavier than the MODX6+ and has the same depth and height.
Seventy-six keys give you six and a quarter octaves. That extra room matters most when you split the keyboard, for example strings or bass on the left and piano or lead on the right, which is common in live shows, wedding bands and church music. It also lets you play most piano parts without constantly changing octaves.
Who it suits: stage keyboardists who play both piano and synth parts, players who use zones and splits, and anyone who finds 61 keys cramped but does not want the weight of the 88-key model.
Where it falls short: it is still semi-weighted, so classically trained pianists may find it light, and at over 1.1 m wide it needs a proper keyboard stand or a long desk.
Yamaha MODX8+: 88 weighted keys
The MODX8+ uses Yamaha's GHS weighted keyboard across the full 88-key range. It is 1,333 mm wide, 404 mm deep and 160 mm tall, and weighs 13.8 kg. That is more than double the weight of the MODX6+.
If you learned on an acoustic or digital piano, the weighted action gives more control over dynamics on piano and electric piano sounds. It also makes the MODX8+ a practical single keyboard for gigs that need full piano range plus synth, organ and string sounds.
Who it suits: pianists, worship leaders, session players covering Bollywood and pop sets on one board, and teachers who want a weighted instrument with a large sound library.
Where it falls short: transport and space. A 13.8 kg board in a flight case or padded bag is a two-hand carry, and weighted keys are slower for fast synth lines and organ glissandos. Budget for a sturdy stand.
MODX6+ vs MODX7+ vs MODX8+: how to decide
Start with the keyboard action
Play style decides this more than anything. If most of your parts are pads, leads, bass and organ, semi-weighted keys suit you better. If you play piano first and synth second, the MODX8+ is worth the extra ₹21,480 over the MODX7+.
Then check range
Count how you use your hands. One hand on synth parts and the other on controls: 61 keys. Split sounds across the keyboard: 76 keys. Classical or full-range piano repertoire: 88 keys.
Then size and transport
Measure your desk or stand. The MODX6+ and MODX7+ are 331 mm deep; the MODX8+ is 404 mm deep. If you gig by cab or auto rickshaw, the difference between 6.6 kg and 13.8 kg becomes the deciding factor very quickly.
Sound is not a reason to step up
Since the sound engine, Performances, effects, sequencer and USB audio interface are identical, you do not gain sounds by buying a larger model. Spend the difference on monitors, headphones or a good stand instead.
What to pair with a MODX+
- Studio monitors: the Yamaha HS5 powered monitor pair (₹32,999 for the pair) connects straight to the MODX+ stereo outputs for a home studio. See our HS5 vs HS7 vs HS8 guide if your room is larger.
- Headphones: the Beyerdynamic DT 770 PRO 80 ohm (₹16,999) or Audio-Technica ATH-M50x (₹11,349) for late night practice in a flat.
- Mixer for gigs: the Yamaha MG10XU (₹17,999) lets you combine the MODX+ with a vocal mic and backing tracks before sending to a PA. Our MG mixer guide compares the range.
- Audio interface for vocals: the MODX+ records its own sound over USB, but if you also record vocals or guitar with studio mics, an interface such as the Audient iD14 MKII (₹27,490) adds proper mic preamps.
- Small stage speaker: a powered speaker such as the Yamaha DBR10 works as a keyboard monitor for rehearsals and small venues.
- Pedals: Yamaha does not list a sustain pedal in the MODX+ accessories, so add one, and consider an FC7 expression pedal if you want to control the Super Knob with your foot.

Owning a MODX+ in India
Power and voltage
The MODX+ runs from an external 12 V DC, 1.5 A adaptor (Yamaha specifies the PA-150 or an equivalent it recommends) and draws 16 W. Yamaha notes the adaptor may not be included in every region, so confirm what is in the box with your dealer. Use only the specified adaptor. In homes and venues with unstable supply, plug the adaptor into a UPS or a surge protected strip, and use a stabiliser where voltage swings are frequent. At outdoor weddings and events running on generators, wait for the generator to settle before powering up your keyboard.
Space in Indian flats
The MODX6+ at 937 mm fits a standard study table. The MODX7+ at 1,144 mm needs a long desk or an X-stand. The MODX8+ at 1,333 mm and 404 mm deep needs a dedicated keyboard stand, and in a small bedroom it will take up most of one wall.
Heat, dust and humidity
Keep a dust cover on the keyboard when not playing, since dust in the keybed and around the sliders is the most common cause of noisy controls. Do not leave the synth in a parked car in summer, and let it reach room temperature before switching on after coming in from a humid or cold venue. Use a padded gig bag or case for transport.
Warranty and service
Buy from an authorised dealer so the warranty is valid and service goes through official channels. Register the instrument with Yamaha as well; registration is also needed for the free Bösendorfer piano download. Back up your Live Sets and user Performances to a USB flash drive before any service visit or firmware update.

FAQ
What is the Yamaha MODX6+ price in India?
The Yamaha MODX6+ is listed at ₹1,59,990 on proaudiobrands.com in September 2026. The MODX7+ is ₹1,68,310 and the MODX8+ is ₹1,89,790. Each price is for one synthesizer.
What is the difference between MODX6+, MODX7+ and MODX8+?
Only the keyboard, size and weight. The MODX6+ has 61 semi-weighted keys, the MODX7+ has 76 semi-weighted keys, and the MODX8+ has 88 GHS weighted keys. Sounds, effects, sequencer, touchscreen and connections are the same on all three.
Is the MODX6+ good for beginners?
It is a deep instrument, but Performances are ready to play from the touchscreen and the Live Set screen keeps favourite sounds one touch away. A beginner who mainly wants to learn piano would be better served by a weighted digital piano, while someone learning synthesis and production will grow into the MODX6+ for years.
Can I use the Yamaha MODX6+ as a 61-key MIDI keyboard?
Yes. The USB to Host port sends MIDI to your computer and there are standard MIDI in and out ports, so it can play software instruments in your DAW. If you only need a MIDI controller and no onboard sounds, a dedicated keyboard controller costs far less.
Does the MODX+ need a separate audio interface for recording?
Not for recording the MODX+ itself. Its built-in USB audio interface sends up to 10 channels to your computer at 44.1 kHz. You will need an interface if you want to record microphones at studio quality alongside it.
How heavy is the Yamaha MODX8+?
Yamaha lists the MODX8+ at 13.8 kg. The MODX7+ is 7.4 kg and the MODX6+ is 6.6 kg.
Does the MODX+ have aftertouch?
No. All three models have velocity sensitive keys (initial touch) but Yamaha lists aftertouch as not available.
