Hi,
Since a few days, these yellow messaages appear in the Max window when i load my (big) patch :

mc.mixdown~: adding more than one perform routine to dsp chain is not recommended
mc.sig~: adding more than one perform routine to dsp chain is not recommended
mcs.matrix~: adding.......
........

all works fine, but I do not know what it is ?
Thx

I have the same message in a regular MSP~ patch. No idea what's causing it!

Max version? Platform? Patch that demonstrates the behavior quickly and simply? Better questions get you better answers.

Hello,
I'm getting the same alert message.
"[object:] adding more than one perform routine to dsp chain is not recommended".
I noticed the problem when I did freeze in my M4L patch, before everything seems to be running smoothly.
And apparently I got the same alert for every MSP object present in the patch.
I'm using bpatchers inside the M4L device, could that be the cause of problems?

I got the same error with a simple polyphonic synth. As I was on this page typing out my question to ask if anyone had solved it, I realised where the error was coming for me.

I got the error 7 times and had a poly~ set to 8 voices, so knew it was something contained in the poly~
My mistake was that instead of out~ I had out for signal output. Changing it solved the problem.

The patch still worked but it is much nicer now not having Max shout at me for reasons I didn't understand.

Posting anyway in case someone else has the problem in the future.
