Summary: Request for different tunings in synth

Initial Comment:
Using the synth effect for something like this: 
   play -n -c1 synth sin %-7 sin %0 fade q 0.1 3 0.1
generates a chord of D + A  (interval of a fifth).

But is it a perfect fifth (just intonation; factor of 1.5 in frequency), or an equal tempered (chromatic) fifth (factor of 2^(7/12) i.e. 1.498 in frequency) or something else?

1. Presuming that sox currently uses equal temperament, please do actually state this in the soxeffect -> synth manpage.

2. It would  be rather neat if sox supported various different tunings. See http://en.wikipedia.org/wiki/Just_intonation for some more details.
