i have been working on a patch for months, focusing on sounds and so on.
Now that it is almost finished i desperately need to get rid of those crackles i keep hearing once every while.
While before i just reset the vector size (with crackles temprarely going away) now i need a permanent solution, and i ask for help.
This is my setup:

i have a max patch which sends MIDI messages to Reason or Kontakt.
So MIDI goes out and comes back via Soundflower 16 ch to Max adc~.
As sound gets back i apply some effects, like reverbs and panning.
The patch itself is not very light, asking – on most stressed moments – for 20% of CPU inside Max (40% on Activity Monitor), while Reason takes another 30%.
But it doens’t seems to be CPU related to me, because crackles happens even at much lower CPU usage, *before* stressing moments.

Here’s my setup:

latest mac mini 2.4 Core 2 Duo, 2 Gb DDR3 ram.
Talking about ram, again, I hear crackles even when i have 200mb+ still completely free.
I don’t use any external audio interface for this project, but actually there’s no latency problems.

Does anybody have some suggestion?
Anything would be greatly appreciated! Pleasee
Thanks!

for example i have not understand
if the crackles exists without the effect line…

or if the soundflower has crackly problems with another patch in your system…

@tim: before i post i need to get rid of all my externals and abstractions… a lot of work, but i’ll try
@Noob4Life: i will try and see if rewire solves… btw, i still have to try Jack, maybe it’s better, don’t know…
@tada good idea: i will try and see if crackles happens if instead of routing back into max and have effects applied, i go directly to audio card
@ Macciza: I have “Scheduler in Overdrive” and “in Audio Interrupt” turned ON.
@ Timothy: I am no t sure of anything *_* so complex, damnit! but now I’ll try to figure out…

again: thanks everyone. Will dig more into the patch and report if anything solves.
