2583.0. "DAC granularity- cc7 vs velocity" by SALSA::MOELLER (Karl has... left the building.) Mon Feb 25 1991 15:34

    I'm working on a piece that seems to want a very soft Kurzweil choir
    part waxing and waning way, WAY in the background of the piece.  This
    started me thinking.. I have 3 ways to shrink the volume of a sequenced
    part.  ONE: Put a CC7, volume event, at the beginning of the track. 
    TWO: leave volume at 127 but shrink velocity over the entire track. 
    THREE: dump the part to synchronized tape at full volume and use the
    mixer fader(s) to shrink the volume.
    
    And of course I started wondering about CC7 vs velocity.. I can't see
    either of them giving me a break on DAC granularity.. quiet is quiet in
    the digital world, and uses fewer bits.  I made a copy of the track and
    did the volume trick on one, velocity on the other.. no discernible
    difference.  I dumped it to two tracks on my Fostex, and compared it to
    live-from-Kurzweil, and was gratified to hear little difference..
    meaning that dolby C and the right tape work just fine.  So the real
    question is, what about DAC granularity and CC7 volume vs. velocity ?
    
    thanks. karl
