Emagic EVOC20 Vocoder (Mac)
The EVOC20 package actually contains three new products. Firstly, the Vocoder with up to 20 bands of filtering and advanced monophonic pitch tracking. Secondly, a Vocoder with a built-in polyphonic carrier sound engine, and thirdly a formant filter bank. All feature an elegant new graphical user interface.
The EVOC20 allows the sonic characteristic of the analysis signal to be printed to the synthesis signal. Its architecture was modelled after the finest analog vocoders. The first unit monophonically tracks the pitch of incoming audio and delivers results which "sing". High and low knobs determine which part of the signal is to be examined. Formant stretch and shift controls encompass a wider frequency range or can shift across it. Resonance controls the "sound" of the vocoder, ranging from soft and purring, through to vicious and snarling. A "freeze" function allows the sonic characteristic of the analysis signal to be captured.
The second unit accepts polyphonic MIDI input for control of its polyphonic sound source — and can be played, just like "classic" vocoders. The third unit is a formant filter bank. It features volume faders for each band, allowing levels to be set freely for unusual effects. It also allows control over filter bandwidth and range via formant stretch and shift.
EVOC20 PS - Polyphonic Synthesizer
The EVOC 20 PS combines a vocoder with a polyphonic synthesizer, playable in realtime. Each of its 16 voices features two oscillators with 50 special waveforms, FM capabilities and colored noise. This synthesis signal can be articulated by any input signal, giving you classic sounds like talking robots, singing strings, percussive choirs and more. Up to 20 filter bands can be used for the articulation process. The Unvoiced/Voiced Detector increases speech intelligibility. Adjust how fast the EVOC20 PS reacts to sound changes in the analysis signal, or capture the harmonic content of the analysis signal with the Freeze function. Formants can be spread, moved or modulated by the syncable LFO for subtle or extreme sonic transformations. Finally, the Ensemble effect provides that familiar warm, swirling sound.
EVOC20 TO - Tracking Oscillator
The EVOC 20 TO architecture is similar to that of the EVOC020 PS: up to 20 filter bands, modulatable formants, controllable filter resonance for sharp or soft vocoder sounds, Freeze, adjustable reaction times and the U/V Detection circuit. But the EVOC 20 TO differs fundamentally from the polyphonic vocoder in its use of an audio track, or the monophonic pitch tracking oscillator, for the synthesis signal. The pitch tracking oscillator follows the pitch of the analysis signal with great accuracy. The oscillator's waveform can be switched between sawtooth and 2 oscillator FM. To provide you with interesting effects in conjunction with the input signal, pitch tracking can be limited to any musical scale. Ultra-surprising sounds result when polyphonic input signals or drums are used with the EVOC20 TO.
EVOC20 FB - Filter Bank
Lovers of analogue filter banks will be thrilled with this plug-in. The EVOC20 FB offers the core of every vocoder, with two distinct, fully adjustable filter banks (A/B). The input signal runs through both filter banks in parallel. Each provides up to 20 filter bands, which can be blended manually or via a syncable LFO. Each discrete filter band features independent level controls with the option to dampen frequencies up to 100%, enabling precise and drastic sound sculpting. Additional filter resonance, adjustable filter slopes, and optional distortion ensures an expansive range of tone colorings. A second LFO, syncable to song tempo, facilitates the modulation of formants through the movement of filter bands. Formant movements can also be manually achieved. As with the two vocoders, stereo spread can be precisely tuned, affording enhanced width to processed signals.
