The Erica Black Multimode VCF has simultaneous HP, BP and LP outputs, CV control over cutoff and resonance for serious modular patches.The core of the VCF is highly stable, custom multimode VCF chip AS3320 (produced in Riga, btw). Bonus feature – unique, adjustable germanium diode overdrive circuit ..
Our Erica Black Polivoks VCF is one of the most authentic sounding emulations of the famous Russian synth, the Formanta Radio Factory Polivoks.The original Russian ICs K140UD12 are used in the sound circuit. We did several updates to adapt the VCF for contemporary modular synth demands.Independently..
As its name suggests, the Erica Synths DJ VCF STEREO module provides sound treatment functionality typically found on DJ decks – it is fully open when the cutoff knob is at 12:00. When turned counter-clockwise, lowpass filtering is applied and when turned clockwise, highpass filtering is initiated. ..
The Fusion VCF3 is resonant 24dB/oct lowpass filter of unique design that combines vacuum tubes and vactrols, providing distinct, soft filtering. For more versatility, the independent audio mixer and buffered multiple is incorporated in the module, and, most importantly – a CV recorder that records ..
Erica Pico LPG is our take on classical Don Buchla LPG designs. We use vactrols in the circuit for that signature sound, and we added some more features, like configurable resonance and built-in decay envelope.FEATURES:Classical LPG soundVCA and VCF modesConfigurable resonanceBuilt-in Decay envelope..
Erica Pico VCF1 is a younger brother of Erica Black Polivoks VCF, designed on the similar topology using rare Russian opamps.As result you get a filter for great acid basslines, screaming resonance sweeps and deep wobbles. Features:Lowpass and bandpass modesSelf o..
'Ivo' is a resonant low-pass VCF (Voltage Controlled Filter), switchable between 2-pole (12dB/octave) and 3-pole (18dB/octave) responses, with voltage control over feedback (resonance) as well as cutoff frequency. It will self-oscillate in 2-pole mode.The module has two audio inputs, one with an att..
'Pandora' is a bandpass filter/distortion processor, based on an unusual combination of power MOSFET transistors and vactrols. Voltage control is provided over the two sides of the filter, the gain, and the filter feedback. A wet/dry mixer is provided, also under voltage control.A range switch is pr..
Cunsa is Frap Tools' quadruple analog pingable multimode resonant filter, saturator, mixer, and oscillator. The module consists of four multimode resonant filters with saturation and feedback control that you can use independently or in various combinations and roles thanks to a series of ..
The FUMANA is an all analog dual filter bank with various control to access dynamically these bands. Each filter bank is composed of an array of 16 independent 48dB/oct bandpass filters. Having two identical filter arrays, allows you to use one of those for spectral analysis (of a modulato..
FIL3 Spectral DevastatorThe FIL3 from Future Sound Systems is a revised form of the sought-after FIL2 Spectral Devastator - a high-pass and low-pass filter coupling, both with unmistakeable character. Originally designed between 2011 and 2012, the Spectral Devastator was designed by Finlay Shakespea..
FIL4 Timbral SculptorThe Timbral Sculptor from Future Sound Systems together several synthesis elements designed for altering the harmonic content of audio signals at its input. The module is comprised of a multi-mode filter, VCAs, a deadband wavefolder, and a rectifier and Lockhart wavefolder in th..
