The core of the VCO is borrowed from famous Russian synth Polivoks VCO and in exponential converter we use the original matched transistor IC that was used in Polivoks. But there are significant updated schematics to have the most out of your modular setup.
Control your drum modules and trigger events on your modular from any MIDI sequencer!
If you want to use a MIDI sequencer to trigger events on your modular synthesizer (e.g. using the hexinverter.net Mutant drums range or Tiptop Audio classical drum modules or envelope generators to control VCAs), Erica Synths MIDI to trigger module is just what you need; it converts ANY MIDI notes to eight 10ms Trigger signals. When designing the module, we put usability as priority; it will take you seconds to program the module. It works with any MIDI sequencer & controller so there is no need to change MIDI controller settings, instead, you reprogram the module.
Polivoks VCF is famous for its’ crazy resonance sweeps and deep, bassy sound which makes it ideal for acid basslines.
We believe, this is one of most is one of most authentic sounding famous Russian synth Polivoks VCF emulations available. 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 buffered inputs, extended Cutoff knob range, eliminated clicks, when switching filter modes, and output stage added to eliminate signal inversion.
The SWAMP is a random CV and audio generator inspired by the famous Wiard Wogglebug module; it’s often the heart of self-generating patches and brings controllable randomness to your modular system.
In the SWAMP module we introduced numerous modifications and improvements to extend potentiometer range, added an audio input, which, when connected, replaces the internal Tone oscillator, replaced the expensive dual vactrol, built S&H circuit around the made in Riga S&H IC AS1100CK2, added audio waveform selection switches, CV output configuration jumpers and much more.
Three random audio frequency outputs
External audio input routed to ring modulator
Three random CV outputs
Clock input and output to sync the module to your modular system
CV control over internal clock for even more extreme randomness
