Hi Fred, I am chiming in here beacause I discovered that partconv~ plays
its convolution kernel (table) once out of its output when DSP is turned
on. 

And I discovered a similar related a few weeks ago (and reported them to
the original author). IOhannes, do you want me to file this as debian
package bug?

I found that the object plays a part of its convolution kernel out of
its outlet when switching tables using a "set ..." message with another
table name. At least this happens in my case. I somehow was able to
measure the length of this unintentional playback. In my case I have a
Pd table of 2048 samples length, partconv~ with 2048 as partition size,
and when I ask the object to (re)read the audio data from the table, it
plays a loud burping noise of approx. 4096 samples length.

It would of course be fantastic to be able to switch between tables without this.

best, Peter
