Great condition keyboard - all keys work with solid weighted key action. All push buttons and controller also is good working order. The case of the keyboard is in great shape - no scratches, cracks or dents. Touchscreen display is in good working condition as well.

The MODX+ 88 is a powerhouse of a workstation, that is also lightweight for an 88 key keyboard. The action is great. I can reset it to factory settings or leave in place many programmed and purchases of Performances. Plenty of remaining user memory.

I gigged with this keyboard since it was released, but recently upgraded to the MODX M. I want to see this keyboard go to a good home and get used all the time, these are the best line of workstations on the market.

Yamaha MODX8+ Product Overview

MODX8+ is a compact, lightweight, 88-key weighted action synthesizer with the piano, instrument and synth sounds pianists need to stand out on the stage, studio or stream.  

 SOUND: The most important element of any instrument is the sound. MODX+ makes all elements of your music sound amazing. MODX+ uses the same technology that powers the flagship MONTAGE: 128 notes of AWM2 (Advanced Wave Memory 2) sample and synthesis polyphony for stunning emulative acoustic instruments, synth sounds and drums. MODX+ also features 128 notes of FM-X (Frequency Modulation) polyphony - a unique, expressive, highly-programmable synthesis technology for dynamic, electro-modern music creation.  

 CONTROL: Every artist wants to find their own sound. Motion Control is designed to bring the sophisticated automation of music production to real-time live performances. All to help you create inspired music that stands out on every stage, studio or stream.  

 MOBILITY: Designed for musicians on the go, MODX+ is compact, lightweight and mobile.  

Key Features From Yamaha Website

 AWM2: The AWM2 engine is exclusive to Yamaha synthesizers and offers much more than just sample playback. Each of the 16 AWM2 Parts feature eight programmable synthesizers with 18 different filter types, amplitude, pitch and filter envelope generators, nine LFOs, 3-band EQ and a dedicated dual insert effect with Virtual Circuitry Modeling.  

 FM-X: Everything you love about the iconic DX7 meets the latest Yamaha innovations. FM-X produces classic '80s or cutting-edge EDM synthesizer sound with incredible dynamic range, power and fidelity. MODX+ goes well beyond the capabilities of the original DX7 with an 8-operator FM architecture, 128-note polyphony, many filter types and more. All with Motion Control for ever-evolving and changing textures to create sounds no one has ever heard before.  

 SMART MORPH: Smart Morph enables morphing between FM-X sounds. Its sophisticated A.I. algorithm creates an interactive morphing map from up to eight FM-X sounds. You can “play” this map from the touchscreen or use the Super Knob to move between two points. The result is a staggering number of interesting and interactive new sounds.  

 256-NOTE TOTAL POLYPHONY: MODX+ features 128-note stereo AWM2 polyphony and 128-notes of FM-X polyphony. Due to the unique architecture of MODX+ and MONTAGE, this polyphony is always available without latency or compromising other features.  

 Integrated Flash: Save your music in a flash. MODX+ includes 1.75GB of non-volatile, low latency user flash memory with high speed reading/writing for your own custom samples or synth libraries.  

 EFFECTS: MODX+ is packed with DSP innovation, power and sound quality to bring you everything from high-definition reverbs to detailed Virtual Circuit Modeling (VCM) effects. Get EDM sound with effects like Beat Repeat, Vinyl Break or Bit Crusher. Use the Spiralizer effect to create the auditory illusion of tone continuously rising or falling in pitch. Add a compressor with sidechain for a modern “ducking” effect. Or go retro with vintage effects like Analog Delay, VCM Phaser or a variety of Amp Simulators.  

 A/D Input: A stereo A/D input allows you to bring external sources like analog synthesizers, vocals and other instruments into the MODX+ motion control system. Control individual parameters with the physical controls or have MODX+ provide “invisible hands” using Motion Control. Add the Vocoder, Envelope Follower and Auto Beat Sync and it's like the A/D input on MODX+ becomes an instrument unto itself.  

 MULTI-CHANNEL USB AUDIO INTERFACE: As expected for modern computer-based music production, MODX+ features a professional 4-in/10-out, multi-channel USB audio interface. A single-cable connection replaces the need for an external audio interface. iOS compatible.  

 Premium Details & Build: Just like the flagship MONTAGE, MODX+ has rubber-coated pitch and modulation wheels for a premium feel when performing. The 88-note weighted Graded Hammer Action MODX8+ comes in at a svelte 30.4 lbs.
