The MIOSimplePitchShifter provides one parameter ( Steps), which is the amount of pitch shift to apply to the signal. The shift parameter has a range of -24 half-steps (-2 Octaves) to +24 half-steps (+2 Octaves), and may take on any fractional value in the range.
There is a small amount of effective delay on the pitch shifted signal, but it is generally not noticable when the shifted signal is summed back with the original signal. Depending upon the frequency of the input signal there may be a small amount of AM modulation in the output signal. This will appear as apparent tremolo on the output.
