I didn't develop the code, but it sounds like you're saying .freq is
acting more like SndBuf's .rate and should be named something else?

I think no (sorry for my English), That I would said that there is not a manipulated freq
but a recorded sample in a particular file format, the acces an behavior are differents

from the standpoint of MIDI manipulation.

What do you mean by this?
