The heart of Frames is a 4-channel digitally controlled analog VCA. Through flexible input/output mixing and normalling options, it can be patched to serve the following purposes (among others): * 4-channel attenuator/VCA. * 4-channel mixer. * 4-channel programmable CV source. * Quadraphonic panner.
I/O: * 4x DC-coupled signal inputs * 4x Attenuated signal outputs * Global signal input normalled to all inputs * Mix output * Frame control CV input * Frame change trigger output
Controls: * 4x Channel level control with LEDs for visualizing levels * Frame control with RGB LED backlight * Frame CV attenuverter * Keyframe creation/suppression buttons
Technical characteristics: * CV inputs impedance: 100k. * Audio input impedance: 100k (25k for the global input in some configurations due to normalling). * Cortex-M3 ARM processor. * Open-source hardware and firmware. * Easy firmware updates through an audio interface.
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!
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.
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.
