Can anybody help me to extend this patch from 4ch to 8ch? (I found it
somewhere...) Or is there an even easier (better) way to do the same.
I already tried [vbap] but the objects [define_loudspeaker] and
[matrix~] are not recognized by my PD-Extended 40.3 on Max OS 10.5.
(see other attachment).
Many thanks in advance for your help, Achim

Well, I don't really have any experience with spatialisation, but if you're trying to make a rectangular-prism structure from a rectangle structure, you will need to add a 3rd [expr], add a new [inlet] and [/ 200], add four more [t f b] 50 [line~] [outlet~], and quadruple the number of [*].
The latter is because now each corner is made by multiplying two things together, and what you want is probably multiplying three things together, so you need 2 [*] per channel. Look at the pattern of wires, how it tries all four combinations of going through [expr] and not going through it, and how the number of combinations grows to 8 when adding a third inlet, and that to multiply the third inlet (or its [expr] counterpart) you need the extra [*] for each.

Attached is a cosine-panner that I built to pan sounds accross a 12x5 speaker matrix [1] (with help by Peter Plessas, thanks again!). If you want to pan to that many outputs, I highly recommend to use the iemmatrix objects, they make things much easier. Never use [matrix~] that object is nameclash-polluted, use [mtx_mul~] instead, an example is in the cospan help file.
Anway you can pan with just [*~] as well using [cospan], it's just a lot more patching work, more error prone and slower.
The basic idea is to create as many [cospan <index> <channels>] objects as you need. Say you want to pan over 4 channels left to right, you create these:
[cospan 0 4] [cospan 1 4] [cospan 2 4] [cospan 3 4]
and send each of them a position in degrees from 0-360. The left outlet of cospan will output the raw amplitudes of the respective channel, the right one will output messages for [mtx_mul~].
Now if you want two-dimennsional panning, you duplicate the setup for each the vertical or y-axis. See cospan16to9.pd for how I did it for the speaker wall (which is called "16:9" although it only has 12x5 speakers.)

Hello Frank,
thank you very much for your patches. I'll have a look at it very soon.
Because of [mtx_mul~] I would like to add iemmatrix to my path list.
How can I set a new search path for a library when the folder is
inside the PD package (because I can't open the PD Contents from the
window that opens.)
Thanks for help.
Achim
