REVPITCH M5000
One of the common purposes for using a pitch shifter is to get the instrument or vocalist to
sound "richer" as a plain effect. Yet, through time the pitch shifter has become more
intelligent and the purposes more complicated. Today there are several different forms of
pitch shifters which can be used in many different applications. An instrument or maybe more
obvious - a vocalist who sings a bit out of tune can through the use of a pitch shifter appear to
sing in key. Another use is to produce harmonies with a single source signal, creating your
own choir in real time. In the basic software there are a few high quality pitch shifting
algorithms that demonstrates the power of the M5000. Specific for the REVPITCH algorithm
you are able to add some ambiance to the signal. The diagram below is an addition to the
signal flow diagram found in the "BASIC ALGORITHMS" module, page 2.
A pitch shift effect is produced as the source signal is replayed either faster (pitch up) or
slower (pitch down) The signals can then be mixed and the harmonies will be produced.
