Packed with sophisticated features
In addition to the AWM2 and FM-X sound engines, the Yamaha MODX6+ 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 Yamahas 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 MODX6+ 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 61-note semi-weighted keyboard to drive it all.
