The Erica Synths Black 3109 VCF/VCA is a lowpass filter and voltage-controlled amplifier combo built around the AS3109 VCF integrated circuit, a contemporary version of the IR3109 chip, found on vintage Roland synths such as the Jupiter series, Juno series and the SH-101.Features24dB/oct lowpass VCF..
Erica Synths Black Quad VCA, despite its compact size, is designed in line with the Black Series Hi-Fi philosophy, our custom pre-emphasis – de-emphasis circuits preserve all the nuances of the original signal.Features4 independent VCAsSelectable lin/log response for each channelManual CV bias and s..
The Erica Synths Black Ring-Xfade is an extremely versatile module for sound shaping. It consists of two unconventional ringmodulators/waveshapers, a crossfader that works both for audio and CV and a VCA. Unlike conventional ringmodulator that works only with a signal present on both signal and carr..
Erica Synths Black Voltage Controlled Amplifier is unique design, hi-fi level VCA with improved attenuation and CV reject levels, and bias control for great tremolo effects.Smooth fading between linear and logarithnic response allows you create versatile percussion sounds. LED bargraph gives visual ..
Fusion Modulator is complex, all analogue modulation source with lots of distinct features. It consists of several blocks – two EMS Synthi functionality inspired looping envelope generators with simultaneous unipolar (0V-10V) and bipolar (-5V-+5V), VCA, Noise generator and Sample&Hold. This make..
The Fusion VCA/Waveshaper/Ringmodulator is a complex sound processor that combines VCA, waveshaper and ringmodulator. It’s not a regular VCA; it can operate as one, but most of the power of the module is in advanced modulations – with two CVs applied simultaneously to different stages of the VCA, au..
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 Modulator combines Envelope Generator and VCA in one module with straight-forward controls for live performances. Features:Selectable AD or ASR modesSelectable lin or log envelope shapesLoop mode without Gate inEnvelope outputGate in and output signal control LEDsWith Pico Series we ..
The Erica Synths Pico VCA2 is compact voltage controlled amplifier module, based on reliable AS3330 chip. It features two independent channels, and the first one comes with the manual offset adjustment, useful for full span vibrato effects. Audio and CV inputs of the first VCA are normalled to the s..
'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..
'Persephone' is a VCA (Voltage Controlled Amplifier) using a discrete JFET as the gain element. The JFET can be tastefully (or violently) overdriven for saturation/distortion effects.Persephone also includes a zero-crossing detector, which can be used to restrict gain changes to zeros in the audio w..
Entangled Sound SourceBrenso is Frap Tools’ primary analog source of articulated waveforms whose degree of entanglement can be precisely set by the musician.Its concept developed from a reflection on the very meaning of the word ‘complex,’ which comes from the Latin verb plector, literally meaning ‘..
