This formant-based vowel synthesizer and filter is crafted for sound designers seeking realistic vocal textures and unique synthetic sounds. It excels at creating lifelike choirs and vocal solos without speech, while also offering creative possibilities for original sound design. The synthesizer features a three-band stereo formant filter bank with a flat response, enabling authentic vowel synthesis with precise control.

Users benefit from two fully morphable datasets and fully automatable parameters, allowing dynamic sound shaping throughout a project. The filter bank can process either its built-in synth or an external stereo signal, providing flexibility in sound manipulation. The interface offers advanced visual feedback, including spectrum analysis with overlaid band controls, jog-shuttles for fine-tuning frequency bands, and global controls for shifting bands and scaling bandwidth.

The built-in stereo sawtooth choir synthesizer includes eight voices, six independent sawtooth oscillators, and a stereo noise source, enhanced by extensive modulation options such as six independent LFOs and Aftertouch support. Its monophonic glider adds expressive playability with glide velocity scaling. Designed to minimize the need for external equalization and ambience effects, this synthesizer delivers naturally wide stereo output for rich, immersive soundscapes.
