Not yet documented in the manual but I have checked it a change to vbap
that is backward compatible

1: vbaplsinit has had the first argument extended.  It was the
dimension and could be 2 or 3.  Now the fractional part times 100
gives a number of the speaker layout, in the range 0 to 99.  Layout 0
is as before.

2: vbap, vbap1 and vbapz take an optional fourth argument in the range
0-99 to select a layout.  This defaults to zero as before.

Question:  in vbaplsinit on says 2.01 but in vbap the argument is 1;
is this clear enough?

Note this does not apply to vbap4, vbap8 or vbap16 as These are being
phased out.  Also does not apply to the vbapXmove opcodes which use
layout 0 only.

I will document soon -- subject to the question above

i think this is clear and a very good solution. just needs to be 
properly described.
thanks for this super improvement!

Documented. I also renamed vbap1 to vbapg so as not to confuse with vbap4 etc

hi all,

i've had a chance to compile and test vbapg.  i cannot get it to work
-- the resulting panning coefficients are all zeroed out.  below are
the test csd i used (modified from the git manual) and the console
output (i'm on osx 10.7, using git sources from this morning).

also, just a small error in the manual entry: "vbap1" is still used on
occasion, instead of vbapg.
