My opinion of the PSR 2000's Vibrato on the Tenor Sax or other Sweet Voices "and non-Sweet Voices,- eg., Harmonica, are very well done on the PSR 2000. They sound very realistic to my ears and they "really" shine when played within Midi Files or the accomplished touch of a skilled Keyboardist . Actually, if you have a Professional Midi File or the equivalent, it is really astounding to how good those Sweet and other Vibrato voices can sound.

Best regards,
Mike
