From Musicradar:
8 FM operators + spectrum widening = the best FM synth in existenceYamaha has taken the wraps off the Montage, its new flagship synth. In contrast to its recent Reface keyboards, which were relatively affordable and offered one type of tone generation each, this is very much an all-rounder, and a serious studio/stage instrument that comes in 61-, 76 and 88-note flavours.
At the heart of the Montage is the Motion Synthesis Engine, which combines Yamaha's AWM2 waveform-based subtractive synthesis engine with a new "modern version of synthesis" known as FM-X. This offers eight Operators, 32 algorithms and seven Spectral Forms.
Other features include Spectral Skirt and Spectral Resonance - which are said to enable widening of the harmonic curve and the shifting of harmonic peaks - plus filters, EQ, an additional Common LFO and effects.
You'll probably be familiar with the AWM2 technology, but in the Montage it delivers 128 notes of stereo polyphony, with the synth having ten times the waveform capacity of the existing Motif XF (in fact, it looks like Montage is the direct successor to Motif). This can be used at the same time as the FM-X engine - the engines can be played in up to 16 keyboard zones and also layered.
Montage also promises a new method of manipulating sounds known as Motion Control. The Super Knob can control multiple parameters simultaneously, Motion Sequences enable you to sync parameter tweaks to tempo, and there's also an envelope follower.
As you'd expect, the Montage comes packed with presets, including a high-quality grand piano and synth sounds from Yamaha's DX and TX synths. It also offers direct connection to a computer over USB - audio channels for all 16 parts are sent to your DAW, as is MIDI data - and it can even be hooked up to an iOS device.
All three Montage models feature a 7-inch touchscreen; the smaller two keyboards have semi-weighted synth action keyboards, while the 88-note model has a hammer action. Availability will be in May, with pricing still to be confirmed.
