In the late 60’s composer Steve
Reich stumbled across a technique he called phasing,
which was to have two identical tape loops that run
at slightly different speeds, the result is that
every possible combination of sound is cycled
through until they arrive back in sync. The result
with a melodic piece of music is that it moves
through moments of chaos and moments of melody.
Brian Eno also used this technique extensively on
some of his Ambient albums. After becoming
interested in this in 2008, I decided to build
myself a simple plugin to emulate the process as it
was surprisingly difficult to emulate with any
software I had at that time. I have now expanded it
to emulate four tape decks and many more features
such as time stretching, filters & FX so that it has
become a much more capable synthesizer.
Phase Shifter is designed more for
playing live, though full VST automation is
supported and having an external controller makes
the process a much more rewarding experience. It
also has a built in recorder so that the output can
be recorded directly to disk. It works by loading up
to 2 WAVs, and is triggered via a midi keyboard.
Middle C will play the WAV at it’s original speed.
It has a lot of potential for producing interesting
sounds, I would be pleased to hear of the different
ways people use it.
