[PD] B16.long-varispeed.pd different pitches and tabread4~ interpolation wrappers

[Peter P.]

Hi list,

I am playing around with pd/doc/3.examples/B16.long-varispeed.pd in
order to see if I can write a wrapper abstraction around it. So far I
have a very hard time to understand how to do it. Has anyone attempted
this so far (apart from Miller having it on his dolist, see his reply
from a few months below)? 

Furthermore I just discovered that the example plays back the sine wave
in the table at slightly different speed, hence pitch. I tried a
playback speed of 294 samples/seconds and the two versions of playback
sound a few hertz apart. Can anyone confirm this by setting the playback
speed to 294 and listening to both versions in that patch either
alternatingly or together (some beating should be audible)?

thanks, P
