Same buffer for input and output?
by Evan Buswell 02 Sep '15

Hello, I'm new to the community so apologies if this isn't the best place to post this. I'm currently working on a pd external that's wrapping an synthesis library I've been working on for a few years. I'll share it when it's in working shape, but it may not be of interest as the library is not specifically tailored to pd and so there's a lot of redundancy with other people's work. I've noticed that sometimes input and output buffers will be identical, e.g. logging the arguments from a lowpass filter, I get: *filter=0x261ab0, n=64, *y=0x32a360, *x=0x329fd0, *f=0x32a100, *Q=0x32a360 -- meaning that Q and y share the same buffer. This leads to weird results when history (i.e. x[i-1], x[i-2], etc.) is needed. My questions are: is this intentional? why? is this sharing somehow deterministic? can it somehow be deterministically disabled with a flag somewhere? There are multiple workarounds, of course, but I figured I'd ask first. Thanks for your help, Evan
