Yamaha MODX M8 88-Key Synthesizer with GHS Weighted Action
The Yamaha MODX M8 is an 88-key music synthesizer with a GHS graded-hammer keyboard and the three-engine architecture it shares with Yamaha's flagship MONTAGE M. AWM2, FM-X and AN-X synthesis, Motion Control and 3,487 preset Performances are all on board.
It is built for pianists and keyboardists who want weighted keys alongside serious synthesis, for live gigs, worship, studios and teaching rooms. At 13.6 kg it is a practical choice for players who move their rig but will not compromise on the full 88-note range.
Key Features

Yamaha MODX M8: 88-key GHS graded-hammer action
The MODX M8 has a full 88-note GHS (Graded Hammer Standard) keyboard with initial touch. The graded-hammer feel gives pianists a familiar, piano-like response for acoustic and electric piano parts, while still handling synth and orchestral sounds across the full range.

Three engines: AWM2, FM-X and AN-X
The MODX M8 pairs AWM2 sample-based synthesis, with up to 128 Elements per Part for detailed pianos and strings, with 8-operator FM-X and the analogue-modelling AN-X engine. Polyphony totals 268 notes: 128 for AWM2, 128 for FM-X and 12 for AN-X, so dense layers and splits stay clear.

AN-X engine for vintage analogue character
AN-X gives you two filters with 10 filter types, pulse width modulation, oscillator self sync, ring modulation, FM, a wave shaper and a wave folder. Voltage drift and ageing settings imitate the slight instability of classic synths, adding warmth and movement to leads, basses and pads.

Motion Control, Super Knob and high-resolution controls
Motion Sequences animate synth and effect parameters in time with the tempo, the Super Knob sweeps many settings with a single turn, and the Envelope Follower lets audio from the A/D input or another Part shape a sound. The knobs, Super Knob, pitch bend and modulation wheels are high resolution for smoother changes.

Part and Scene control for live piano-led sets
Dedicated Part and Scene buttons give quick access to 8 Parts per Performance, with 8 sliders, 4 knobs and 4 pedal inputs for hands-on control. At 13.6 kg the MODX M8 is a manageable weight for an 88-key synthesizer, so it can move between home studio and stage.

Touchscreen editing and stereo A/D input
A 7-inch colour touchscreen with six display knobs speeds up browsing and editing. The stereo A/D input, with two insertion effects of its own, lets you route an external instrument or audio source into a Performance and process it alongside the internal sounds.

MODX M8 as a USB MIDI 2.0 audio interface and DAW controller
A single USB cable handles MIDI 2.0 data and multichannel audio, with 10 outputs and 4 inputs at 44.1 kHz. The dedicated DAW Remote button turns the panel into a controller for Cubase, Logic, Pro Tools and Live, and Cubase AI download information is included to get you recording.

Expanded Softsynth Plugin for your DAW
Registered MODX M owners get the Expanded Softsynth Plugin free of charge. It recreates the instrument inside your DAW, so you can build, edit and mix Performances for your MODX M8 even when the hardware is not with you.

Frequently Asked Questions
How does the MODX M8 compare with the MONTAGE M8x?
Both offer 88 keys and the same AWM2, FM-X and AN-X engines. The MONTAGE M8x adds a GEX keyboard with polyphonic aftertouch, higher polyphony (256 AWM2 and 16 AN-X notes) and 3.7 GiB of user wave memory, but weighs 28.1 kg. The MODX M8 uses a GHS keyboard without aftertouch and weighs 13.6 kg, less than half as much.
Should I choose the MODX M8 or the CK88 stage keyboard?
Both use an 88-key GHS keyboard. The CK88 is a straightforward stage keyboard with built-in speakers, battery operation and 363 Voices. The MODX M8 adds full synthesis with three engines, Motion Control, a sequencer and a multichannel USB audio interface, making it the stronger choice for sound design and production.
Is the MODX M8 good for pianists, and does it have aftertouch?
Yes, its 88-note GHS graded-hammer keyboard is the most piano-like action in the MODX M range. It responds to initial touch (velocity) but does not have aftertouch; expression can come from the wheels, Super Knob, sliders and pedals.
Can I record into a computer with the MODX M8?
Yes. One USB cable carries MIDI 2.0 data and audio, with 4 inputs and 10 outputs at 44.1 kHz or 2 in/2 out at 44.1, 48 or 96 kHz. The DAW Remote button controls Cubase, Logic, Pro Tools and Live, and Cubase AI download information is included.
What comes in the box with the MODX M8, and how is it powered?
Yamaha lists the PA-300C AC adaptor, a Quick Guide, Cubase AI download information, Expanded Softsynth Plugin for MONTAGE M/MODX M download information, manual download information and a welcome card. The MODX M8 runs from the PA-300C adaptor and draws 19 W.
How big and heavy is the MODX M8?
The MODX M8 measures 1,310 mm wide, 391 mm deep and 152 mm high, and weighs 13.6 kg. It is larger than the 76-key M7 (7.6 kg) because of its full-length weighted keyboard.
