Modern Synthesis, Reimagined: MODX+

Get to know them!

Yamaha’s MODX series took their suite of creative and technological prowess and packed it into a high-performance synthesizer, engineered for modern needs. The MODX+ builds off this forward-thinking model to accommodate even greater sonic opportunities, bringing your total polyphony to an astounding 256 notes. Plus, the MODX OS introduces new features that include Voices and Live Sets, offering robust flexibility in both composition and performance. The onboard flash memory has been upgraded to 1.75GB, creating more room for your sounds and samples from your collection for more personalized expressive potential. Like its predecessor, the MODX+ is packed with powerful technologies ported from Yamaha’s flagship Montage series. State-of-the-art upgrades from their MOXF line include the AWM2 sample and synthesis engine, fortified with eight times more waveforms, alongside a powerful 8-operator FM-X engine modernized for amazingly dynamic sonics and complex sound design, as well as Motion Control Synthesis for seamless integration and powerful control of both sound engines.

What's new with MODX+

  • 256-note total polyphony, with 128-note stereo from the AWM2 engine and 128-note FM-X
  • MODX OS provides expanded instrumentation and composition abilities, including new features with Voices, Live Sets, and more
  • 1.75GB expanded onboard flash memory to personalize your library
  • GHS weighted action mimics acoustic pianos with heavier keys in the low end, lighter at the high end

Packed with sophisticated features

In addition to the AWM2 and FM-X sound engines, the Yamaha MODX8+ is packed with sophisticated features (many handed down from Montage), including the Super Knob, which gives you simultaneous control over multiple parameters; the ability to send 10 and return four audio channels plus 16 MIDI channels to/from your computer or iOS device over USB; Live Sets, which allow for Performance organization without copying, renaming, or changing order; and an A/D input that processes external audio sources through the MODX+ DSP.

Also onboard is Yamaha's Motion Sequences feature, which drives synth parameters via rhythmic control data you can intuitively interact with in real time; an Envelope Follower that lets you use internal or external audio as a synth parameter control source; and a Vocoder effect that re-creates the classic voice-synth sound. Four-part Seamless Sound Switching, the capacity for 27 simultaneous effects, an onboard 4-in/10-out audio interface, and 1.75GB of internal flash memory complete the feature set. The Yamaha MODX8+ gives you a powerful modern synthesizer, a potent controller with a multichannel USB audio/MIDI interface for extensive DAW and VST control, and an expressive 88-note GHS variably weighted keyboard to drive it all.

A powerful instrument that does it all

Keyboardists at Sweetwater have long respected the top-notch sounds Yamaha loads into their keyboards, and the Yamaha MODX8+ is no exception. From stunningly realistic acoustic and electric pianos, guitars, basses, and drums to orchestral instruments to vintage and modern synth sounds, each patch is expertly crafted down to the finest detail, so you can call up any preset you like and never have to worry about tweaking your tone. When you're in the mood to patch from scratch, however, the Yamaha MODX8+ provides a robust set of sound-sculpting tools for realizing your ultimate musical vision.

Add to that a full complement of VCM-based effects and processors, and you’ll never run out of creative possibilities. Yamaha's MODX8+ boasts a broad selection of effects for both the internal sounds and for use with the A/D inputs, giving you access to the same effects found in Yamaha's professional digital recording consoles. And the Yamaha MODX8+ supports the use of 27 effects simultaneously, so you can polish your tracks to perfection.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
