Maneco Grone Expander Eurorack Module

Manufacturer's description

A four-voice touch-controlled drone module, featured two drone oscillators as used in the Grone Drone module, plus two wavetable oscillators, two multi-waveform LFOs, a modulated delay section and a dirt stage at the output. The Grone Expander can be used standalone or processed through Grone Drone’s external input.

Oscillators 1 and 3 (Bytebeat oscillators)

• Produces sound based on equations converted to analogue signals.
• Sixteen equations are selectable via Up and Down switches.
• Four LEDs display the equation number in binary format.
• A0, A1, A2 pots modify parameters used by the equations.
• Sample Rate pot adjusts pitch and oscillation speed.
• Output Level pot sets the oscillator output volume.
• Dedicated output jack for routing the oscillator's sound to external modules.
• Hold Mode: Toggle switches allow selection of Fast Decay, Long Decay, or Hold Mode for the touch-trigger input.
• CV inputs allow external pitch modulation.

Oscillators 2 and 4 (Wavetable oscillators)

• Digital oscillators controlled via touch or gate inputs (gate-controlled by gate jacks).
• Pitch pot adjusts oscillator pitch.
• Modulation Source: LFO A or LFO B (selectable via toggle switch).
• A0 pot selects the waveform.
• A1 pot morphs between two waveforms.
• Individual output jacks for each oscillator.

LFO 1 and 2

• Low-frequency oscillators routed to modulation inputs for Oscillators 2 and 4, as well as the delay section.
• Rate pot sets the LFO speed.
• Waveform Shape pot selects the LFO waveform.
• Available waveforms:
• Ramp up
• Ramp down
• Square
• Triangle
• Sine
• Sweep
• Random levels
• Random slopes

Delay

• Processes the combined output of all oscillators.
• Time pot adjusts delay time.
• Feedback pot controls delay feedback (capable of self-oscillation).
• Level pot sets the delay output level.
• Modulation Amount pot sets modulation depth from LFO 1 or LFO 2 (toggle-selectable).

Output section

• Grit pot adjusts the amount of overdrive.
• Level pot controls the final output volume.
