The tELHARMONIC is a Multi-Voice, Multi-Algorithm synthesizer module named for the music hall considered by some to be the location of the first electronic music concerts. It was coded by Tom Erbe with the goal of presenting three historically important pioneering electronic tone generation techniques less often implemented within the modular synthesizer.
The tELHARMONIC’s roots go back further than the advent of electronic music, as it also takes a new approach to handling music theory in the modular context. TONIC, INTERVAL, DEGREE and D-GATE, allow for patch-programming of complex chord progressions, scales, melodies and playing styles. This Voltage Controlled Music Theory guides the Algorithms in a unified way, whereas CENTROID, FLUX and H-LOCK sculpt the timbre of each Algorithm uniquely, allowing for complex sounds to be created around a unified melodic structure and pattern.
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
The core of the Envelope Generator is borrowed from famous Russian synth Polivoks, but significantly updated schematics – eurorack standard positive gates, envelope amplitude, inverted envelope output, looping feature (looping on gate on). Bonus feature Gate Delay – the module outputs delayed gate signal after Attack stage. Chain up several (4-5) Envelope Generators, each with delayed gate to create evolving polyphonic synth-like pads!
Use Fusion Mixer as two independent 3-input mixers (also for stereo signal mixing) or 6-input mixer. Special feature of the Fusion Mixer – great tube overdrive effects when level knobs are set to 3 o’clock and above. When used with drum machines, it even emulates side chain compressors. When used to mix signals from VCOs Fusion Mixer works as wave shaper, especially, if pulse width modulated pulse signals is used in one of inputs.
All Fusion modules by default are configured to work with regular eurorack PSU.
