There is now a Debian source package as part of the nightly builds, so it
should be much easier to build Pd-extended on Debian these days. After
downloading the two tarballs:

Hi Miller,
Thanks for the solution. The routines are in place so copying the
right channel input to output should do it. Is there any reason to
prefer copy_perform() over memcpy()? I'm trying to make the most
efficient reverb for RPi Co.
Katja
On Fri, Jan 11, 2013 at 7:57 PM, Miller Puckette
Ok so I did the ugly thing with the right channel input and output pointers:
memcpy(outR, inR, vectorsize * sizeof(t_float));
inR = outR;
Works like a charm, thanks again.

copy_perform assumes the data is 4-byte
Function copy_perform8() is also eligible for SIMD processing. I used
memcpy() because it is straightforward to use, while Pd's functions
pointed to the wrong locations for this case. On the reverb's total
load there is no significant performance difference.
