i've never had a problem with [pix_data] at audio rate, using something
like the following:

[inlet~]
|
[tabsend~ $0-x]

[bang~]
|
[64(
[until]
|
[i]
[+ 1]
[% 64]
|
[tabread $0-x]
|
[pix_data]

there's two "tricks":
- converting the signals to message domain, using [table]
- accessing multiple pixels in zero logical time (using [until])
