Ken, you might want to check out Stuart Smith et al's 1994 ICAD paper on
using granular synthesis for sonification. The perceptual testing they did
indicated a lot of interaction between parameters. However, if you're
looking for broad navigation aids rather than precise indicators, this may
not be too disruptive.

I think this tradeoff between precision of representation and
non-orthogonality of auditory variables is going to be an important issue
for all of us. It is also an issue that points up the distinctions and
inter-relationships between psychometrics and task-oriented design.
