In addition to the realistic piano Voices you can enjoy, the CSP also features a wide collection of other authentic acoustic and electric instruments. The CSP-170 features hundreds of high-quality instrument Voices including "Natural!", "Sweet!" and "Cool!" Voices sampled specially to compliment the instrument types. Yamaha's Super Articulation Voices (SA) add genuine performance attributes of the real musical instruments as though they were being naturally performed by a virtuoso of that instrument instead of from the keys of a piano keyboard. Examples include "fret noise" or "body knocks" from a guitar or the "inhales", "exhales" and glissandos from wind instruments. By simply varying your touch and playing techniques or using the pedals, SA voices will add significant authenticity to your sound.
