Do voices like sweet flute, and sweet tenor in the PSR-2000/2100 have a vibrato programed into the voice? I say this because when I play the sweet tenor on my PSR-550, even though I have no modulation wheel, the voice has vibrato programed into it. This would normally be accomplished with a modulation wheel for more control over the voice. Do the PSR-2000/2100's have this vibrato in the voice, and if so does it conflict with using the modulation wheel?
