[PD] Audio Matrix~

[Gintaras Lau.]

Hello,

I'm having fun to create audio signal router with [matrix~].
Everything seems easy, just why I got DSP loop error when trying to
conect a signal from [pd effect 1] back to matrix free inlets

0  1         2   3
|    |         |    |
[matrix~ 4 4 1]
|0    |1     |    |
|      |
[pd effect 1]
|      | <-to 2 3

?
