VoMPE (Voice over MIDI Polyphonic Expression) is a unique audio tool that converts voice input into polyphonic MIDI notes by analyzing formant frequencies. By examining the distinctive characteristics of the voice, it translates vocal nuances into MIDI signals, enabling musicians and producers to creatively integrate vocal expressions with digital instruments. This process opens new possibilities for expressive performance and sound design.

The plugin works by modeling voice production, which involves the vibration of vocal cords combined with the resonance of the vocal tract. It estimates the spectral envelope of the voice, representing the resonant frequencies known as formants. These formant frequencies are key to capturing the unique tonal qualities of the voice. VoMPE divides this spectral envelope into frequency bands, each corresponding to a MIDI channel, and outputs MIDI notes based on the strongest formant amplitudes in each band.

Available as a VST 3 plug-in for Windows 11 64-bit systems, VoMPE supports sampling rates of 16kHz, 44.1kHz, and 48kHz, making it compatible with most digital audio workstations. This ensures smooth integration into music production workflows, allowing users to seamlessly harness the power of voice-driven MIDI control. VoMPE offers a fresh approach for artists seeking to expand their sonic palette through voice-controlled MIDI expression.
