This Application will take a single-pitched audio source and transpose it in real time
according to the supplied MIDI notes. My main motivation to create MIDI Choir was to be
able to sing harmonies live, however the product may also be used for studio work.
Below are some of its key features.
Reliable ASDF pitch tracker with voiced/unvoiced recognition
Pitch tracking indicator
Separate processing of voiced vs. unvoiced input, thereby preserving a natural, intelligible sound
Voiced input will be re-pitched according to the keys pressed
Octave, semitone and fine tunig controls
Built-in noise gate with indicator
Built-in soft knee limiter with color-coded LED indicator
Built-in stereo reverb with controls for room size, damping, stereo width and dry/wet mix,
Master volume control with output clipping indicator
Effects may also be used without MIDI input
Option of VST plugin or stand-alone executable
