i tried to use vbap in this way:

    nchnls = 4
    vbaplsinit 2, 4, -45, 45, 135, -135

    ...

    aOut[] vbap aTon, iAzi, 0, gkSpreadToene
    out aOut

it did not work (csound segfaults), and i think it is simply related to 
the fact that csound expects the array to be created before, like:

    aOut[] init 4
    aOut vbap aTon, iAzi, 0, gkSpreadToene
    out aOut

can vbap be changed so that it can be used as i expected (and as it is 
written in the manual)?

the size of the audio array would depend on the ilsnum in vbaplsinit 
(perhaps different in different setups).

I thought one was allowed more than one speaker array so vbap would need 

yes it must be related to the speaker setup, and in a setup to the 
number of loudspeakers.
for instance:

  vbapslinit 2.01, 4, ...
  vbaplsinit 2.02, 6, ...

aOut[] vbap aSound, kAzi, 0, 0, 1  -> aOut is of length 4
aOut[] vbap aSound, kAzi, 0, 0, 1  -> aOut is of length 6

last line must read setup 2, so correct is:

I think I have it working.  Will commit in a minute but this example runs


; Select audio/midi flags here according to platform
-odac  ;;;realtime audio out
;-iadc    ;;;uncomment -iadc if realtime audio input is needed too
; For Non-realtime ouput leave only the line below:
; -o vbap.wav -W ;;; for file output any platform



sr = 44100
ksmps = 32
nchnls = 4	;quad
0dbfs  = 1

vbaplsinit 2, 4, 0, 90, 180, 270

instr 1

asig diskin2 "beats.wav", 1, 0, 1	;loop beats.wav
kaz  line 0, p3, p4			;come from right rear speaker &

it is new (if you follow back this thread) so can only work if you build 
csound from git develop.
