I SURE agree with you guys that Vari-PITCH- (you had to do it with tape SPEED in the old days) is an essential tool for recording/overdubbing real instruments in the studio. I mostly record clients and groups- in the studio- by the hour, for money... there is nothing easier and faster than just one-slider tuning the song to any instrument that walks through the door!
More especially, the instruments that you just can't easily tune- like Hammond organs, REAL grand pianos, Fender Rhodes, nasty old Clavi's, pipe organs, pump organs, harps, accordions, harmonicas, zithers, melodicas, harpsichords, tubular bells, ethnic drums, 12-strings, sitars, xylophones, native american wood flutes, bagpipes, autoharps, bowed psaltries, pan flutes, Farfisas, dumb little toy keyboards... dang- it's a long list of coolness! Synthetic emulations of these instruments are great- but there's absolutely no comparison to the real thing for cool.
It's SOOO much easier to be a creative and excellent Recording Studio if you can just one-slider-tune the song to a fun, unusual overdub! I collect odd acoustic instruments from all over the world, and part of the cool vibe of my studio is that there's hundreds of strange and interesting noise toys hanging all over the walls. People love trying the strange thangs...
Sure miss Vari-Pitch.
