well yes, true.
i keep forgetting of abominations like running a 32-bit Pd on a 64-bit OS.

In reality, it's even less, usually 2 GB, which is a bit more than 1,5 hours of stereo audio @44100 Hz. Pd will give you a warning when you try to exceed this limit ("pd: resizebytes() failed - out of memory").

how much RAM does that machine have?
decent OSs should be able to manage more than a total 4GB of RAM even
when the entire OS is 32bit (a single application will not be able to
address more than 2^32 bytes though; but it should get you closer to
really having 4GB, rather than 2GB)

but yes, in order to make use of 32GB of memory you need a native 64bit
application (running on a 64bit OS).

fun fact: on linux, you can use 64bit Pd for >10 years with virtually
all external libraries working.
