     As far as I can tell, the answer to your question is "true". I just
recently wrote some code which was to play a soundwave which was between 16 &
32k in length. However, I was under the assumption I could place this sound
wave so it started on pretty much any bank (in the lower 32k half of the DOC
ram). It didn't work that way, however. No matter where I told the oscillator
that the soundwave started, it would always round (or truncate??) the bank
number so that it started playing from either the 0k or 32k position. That 
leads me to believe that you must start your wave at a position that is evenly
divisible by its size (as stored in the oscillator's wavetable size register).
I can't say that I have read confirmation of this anywhere (it doesn't - as far
as I know - specifically say this in the Hardware Ref. or any other reference
books I have). Has anyone else?
