When the Yamaha S90 was released in August 2005, it marked a huge step in digital piano and synthesis technology. Its Motif ES roots and its other capabilities aside, the Yamaha S90 is the better sounding and feeling digital piano/synth we’ve played so far.
The piano keyboard runs on the new multi-velocity, the stereo grand piano sample with soundboard simulation and half dampening (when combined with the FC3 pedal) that’s rich and incredibly realistic. So far, it’ the best Yamaha has used in a synthesizer.
The studio connections compatibility, 128 note polyphony tone generator, PLG expandability, and mLAN expansion slot give it all the synthesis control and powerful functionality of Yamaha MOTIF ES.
