[PD] How can I weave multiple signals together?

What comes to my mind is to write the three signals on three new arrays
which are three times the size of the original ones. These arrays would
have each sample from the original signal zero-padded by two samples. That
can be done by reading the original signals with tabread~ at a rate which
is 1/3 of the initial one (hence repeating each sample three times) and
multiply that by a function which is 1 every three samples (the first
sample should be 1). That, for example, could be a phasor~ with a period of
three samples followed by a [<~ 1/3] (it can be implemented with a max~,
-~, and /~). (44.1kHz SR seems to be too tight; use 48kHz.) Of course,
you'll need to sync all the phasors and writers involved with a bang. The
resulting signal could then be obtained by summing the three arrays,
delaying the second by 1 sample, and the third one by 2 samples.

I hope it works.
