PERFormant is a sound designer-oriented formant vowel synthesizer / filter.
It is ideal to design realistic choirs or vocal solos (non-speech), can also be used creatively to design original synthetic sounds and textures.

3-bands, non-resonating stereo formant filter bank with flat (Butterworth-like) response, for astonishingly realistic vowel synthesis.
2 fully morphable datasets.
Fully automatable parameters.
The filter bank can be switched to process either the builtin synth or an external stereo signal.
Very advanced and carefully designed graphical user interface: bands controls overlaid on the builtin spectrum analyzer for visual feedback; jog-shuttles for accurate fine-tuning of the three frequency bands; global band shifter and bandwidth scaler.
Builtin stereo sawtooth-choir synthesizer (eight voices, six independent sawtooth oscillators plus stereo noise source) with extensive modulation controls; six independent LFO (sine or random) working in FM, AM or both; extensive Aftertouch support; monophonic glider with glide velocity scaling.
By design, need for external equalization is dramatically reduced / eliminated.
Naturally wide stereo output, no needs for external ambience simulators.
