matrix~ limited to 32 32?

May 13, 2006 | 8:26 pm

Hi!

I want to use a matrix~-Object with 64 inputs and 64 outputs. But i doesn’t
work, if I connect them more than 32 patch-chords to the inlets. Is there a
limitation of number of possible inlets and outlets? I use a PowerBook G4
1GHz, OS 10.4.6 Max/MSP 4.5.7.

Sorry for my posting "matrix~ limited to 32 32?". I figured out, that not
the amount of inlets and outlets is the reason. I made some effect with MSP
like filters and delays and want it route with a matrix~. At first I
connect the outlet of matrix with the effect-subpatch and than the output
signal of the effect-subpatch with any inlet of the same matrix~. An than
matrix~does’nt work anymore. Maybe matrix~ prevents a possible feedback?

Indeed. Feedback loops in MSP will stop the sound. You need to
introduce a small delay, by the use for instance of a send/receive pair
(then the delay will be as small as possible, i.e. 1 vector).

You need to delay the signal by one vector – the easiest way is to
use a send~/receive~ pair for sending the signal to the matrix~
inlet. There’s also an abstraction in the tap tools set that does the
same thing.
