hi pd people,

I have just started working with pure data and the latest pd-extended release.

I like to do spatial panning with vbap for multiple objects. Unfortunately i can't get the matrix~ object to work.
pd always tells me:

load_object: Symbol "matrix_tilde_setup" not found
load_object: Symbol "setup_matrix0x7e" not found

my startup list:
gem
cyclone
zexy

my paths:
C:/Programme/pd/extra
C:/Programme/pd/extra/cyclone
C:/Programme/pd/gem
C:/Programme/pd/extra/zexy

btw. i can't find any *matrix* files in ZEXY at all, only in cyclone.

is there a simple way to make all pd-extended extras accessible at once?

thanx!

there was some problem with matrix objects existing in different libraries. the matrix you need is part of the iem library, i think it's called iemlib.

also, you can make his object using its abbreviated form [mtx]

it's a really good object too. so i hope you find it!

download from hans.... his extended packages are good.

sorry, not gonna post the url again today. just google "hans pd extended download" and you'll find it.

Hi Hardoff,

[mtx] works, i can print out the matrix message. [matrix~] doesn't, I can't control the coefficients. The helpfile für [matrix~] sucks.

For example, if I have a [matrix~ 2 2] object i'd expect a message like [1 0 0 1] but in most cases the matrix doesn't do anything.

Ok, to make it more precise. What I want to do is to play multiple VBAP-panned sources on a 16-speaker array. At the moment i work with [*~] and [throw~ ch01] [throw~ ch02]... for each source. This seems to be not very smart and my system goes down with more than 3 sources. I hope to implement VBAP for at least 8 sources.

So I'm looking for a way to process the signals more efficiently, theat means that only those channels are calculated which are really used (max. 3 channels per source , without Spreading). I thought [matrix~] to be a better way than [throw~]&[catch~].

Maybe there's another, better solution?

Well, it works now,

if anyone is interested. The Cyclone Matrix~ comes from MAX/MSP. It has two modes - binary and non-binary. Call it up with [matrix~ r c] r=number of inputs (rows), c=number of outputs (columns)
If you want non-binary mode (like me), type [matrix~ r c f] with f as a float number.

To modify a value, send a message like [c r v] with c= input number (int 0..n), r = output number (int 0..n), v=value (int 0/1 in Binary, float 0..1 in Non Binary Mode)

Have Fun!

cheers, thanks for posting the solution.
