Maneco Labs GRONE MANECOLIN (Table Top)


This model takes remote inspiration from Rob Hordijk ‘s Benjolin, but based on different architecture and electronics.



The whole concept takes place around two digital oscillators , Oscillator one is based on Wavetable , and the second is a wavefolder one . Several cross modulation options exist , and both are combined to generate chaotic modulations via a shift register, which is called Rungler .



Both oscillators are also combined by a comparator that outputs square waves with variable duty cycles .



Further processing includes an MS20 filter, also with modulation options , and a final reverb capable of massive self oscillation.



Oscillators:

Contain controls for Pitch , Rungler modulation, external CV with 1v/ oct (approx) , normalized to the other oscillator audio output for FM type generation , LFO modulation , Wave 1 in osc1 is wave select , wave 2 is crossfade between two waves , while in oscillator 2 Wave 1 is wave folding and wave 2 is overtones .

connections for both oscillators are CV control and individual output.



Noise : adds white noise to the oscillators mix

PWM mix : sums square wave from oscillators comparator

LFO : controls for rate and wave selection, led indicator and corresponding output.

Filter: Low pass MS20 like filter , controls for cut frequency and resonance ,with LFO and Rungler modulation , connections for external audio input , external CV control and direct filter output .

Rungler :Shift register whose data is derived from oscillator one square wave output , and clock from selectable oscillator two square out or LFO rate , switch control.



Both clock and data have external inputs normalized to the internal sources.



its output and XOR signal also has dedicated outs Reverb :



Datorro architecture reverb with controls for blend and decay, will turn infinite on higher decay settings. Can also process external signals via dedicated input

Output finally has a GRIT option for saturating audio and level control



Power: 9VDC center negative Tip (Boss style), not included
