Certainly some of Logic Pro 7’s wildest effects come in this category. They let you for example add an ethereal unreal appearance to a natural voice. But Filters also play an important role in tweaking vintage keyboard or classical analog synthesizer sounds. And could you imagine a modern dance music without some funky filters?

EVOC20

EVOC20 provides three powerful tools for sound design: A classic polyphonic vocoder with built-in synthesizer, a formant filter bank and a pitch tracking vocoder. Each plug-in provides maximum flexibility and features pristine 32-bit sound quality.

Playable in realtime, EVOC20 PS combines a vocoder with a polyphonic synthesizer. Each of its 16 voices feature two oscillators that offer 50 special waveforms, FM capabilities and colored noise. This synthesis signal can be articulated by any input signal, resulting in classic vocoder sounds, such as 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 audibility. You can adjust the sensitivity of the EVOC20 PS to 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 — and further processed by the incorporated Ensemble effect, providing that familiar warm, swirling sound of vintage vocoders.

Similar in architecture to that of the EVOC020 PS, the EVOC20 TO offers 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. The EVOC20 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. For interesting effects in conjunction with the input signal, you can switch the oscillator’s waveform between sawtooth and 2 oscillator FM and limit pitch tracking to any musical scale. Truly surprising sounds can result when you use polyphonic input signals or drums with the EVOC20 TO.

Lovers of analog filter banks, prepare yourselves for 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 you can blend manually or via a syncable LFO. Each discrete filter band features independent level controls, with the option of frequency dampening by percentage, enabling precise and drastic sound sculpting. Additional filter resonance, adjustable filter slopes and distortion affords an expansive range of tonal colors. A second LFO, syncable to song tempo, facilitates the modulation of formants through the movement of filter bands. You can also achieve formant movements manually. As with the two vocoders, you can precisely tune the stereo spread, providing enhanced width to processed signals.

AutoFilter

The AutoFilter creates classic, analog-style hardware synthesizer effects. It features a selectable low pass filter slope (6, 12, 18 or 24dB), a complete ADSR and a powerful LFO, with speed modulation on the input signal. As higher resonance values cause the filter to cut the bottom end, signals tend to sound thinner. The Fatness parameter compensates for this audio artifact. The distortion effect on the input and output of the Autofilter will delight fans of aggressive sounds. The resonance controller invites you to experiment, as self-oscillation is initiated before you max out the parameter.

Vocal Transformer Audio Player

Vocal Transformer changes the pitch and formants of your audio independently, so you can transform your lead singer into a falsetto, or roboticize your chorus. Learn more...

Fuzz and Wah

The Fuzz and Wah effects — borrowed from the EVD6 Clavinet — combine in a single plug-in that for use in processing any sound source in Logic Pro 7’s Mixer. The Wah effect provides six different filter types that simulate legendary effect pedals such as the Morley or CryBaby. The envelope can be changed and automated onscreen — or controlled via MIDI. The distortion of the Fuzz-Wah works on frequencies between 2000 Hz and 20,000 Hz. You can control every sonic detail with parameters that influence intensity or compression, for example. The AutoGain function guarantees the maximum peak level, without overloads, preventing mix artifacts when you use extreme settings.

Guaranteeing Compatibility

Despite of offering much better sounding and more efficiently processing filters in its present version, Logic Pro 7 still comes with High Cut, High Pass, Low Cut and Low Pass Filter. This enables you to open projects that have been started on earlier versions of the application.
