The heart of the ES is a brand new tone generator chip featuring 128 notes of polyphony, new filter algorithms and massive DSP power (try 16 three band Part EQs, 8 Insert effects, 2 system effects and 2 master effects in Song and Pattern Mode). To compliment all this sonic power, the ES has the largest and most musical wave ROM ever featured in a workstation (175MB in 16-bit linear format). New features like Phrase Factory with 1700 arpeggios, Mega Voice technology and real time loop remix makes it easier than ever to create great tracks. Its advanced Integrated Sampling Sequencer lets you add audio tracks into your songs.

The latest in digital technologies including support for 512 MB of DIMM Sample RAM, USB storage hosting and 2nd generation mLAN computer connectivity guarantee future expandability. Yamaha added bigger & better knobs, sliders and transport controls, even a ribbon controller. In fact, ES might stand for Every Suggestion Yamaha ever heard for improving MOTIF.
