I think Kris may be refering to the new Yamaha PSR2000. If in fact the PSR2000 keyboard does not support aftertouch, I too would find it extremely limiting to trigger the required vibrato needed to realistically emulate string (violin, cello, string section) and wind/reed instruments (flute, sax, etc). This feature is too important to leave out (in my opinion). Can someone here PLEASE verify if the new Yamaha PSR2000 supports aftertouch or not? Somehow I think incorporating the vibrato in the sample itself would not work, (would it?!) I'm interested in hearing from others on this. - Scott
