Schlappi Engineering Angle Grinder

Schlappi Engineering’s Angle Grinder is a quadrature sine wave oscillator with integrated filter and waveshaper. It features a dedicated Spin section, which houses its quad sine wave oscillator. An adjacent Grind section evaluates each phase in relation to the input signal before removing the resulting increment from the input signal. If the Spin section is excessively damped, the Grind section will cease oscillation and the module can be used as a crude state variable filter.

Angle Grinder Features

  • Quadrature sine wave oscillator
  • Can be oriented as a state variable filter or wave shaping effect
  • Spin section features 4x phase related outputs: 0°, 90°, 180°, 270°
  • Grind sliders mix signal to Grind section
  • Audio/CV input
  • Output: direct our from Grind section
  • Inject input patches straight to Spin section
  • 1v/Oct cv control over Spin
  • Damping section neutralizes oscillations
  • Range switch moves between Low (0.1Hz to 500Hz) and High (10Hz to above 20kHz)
  • Eurorack module
  • Width: 18hp
  • Depth: 81mA @ +12V / 78mA @ -12V

Schlappi Engineering Angle Grinder & Interstellar Radio
Schlappi Engineering has two gritty and noisy eurorack modules. The Angle Grinder (https://www.perfectcircuit.com/schlappi-engineering-angle-grinder.html?utm_source=perfectcircuit_youtube&utm_medium=video&utm_campaign=schlappi) is a quadrature oscillator and filter with built in complex feedback paths for squaring up and distorting the signal. The Interstellar Radio (https://www.perfectcircuit.com/schlappi-engineering-interstellar-radio.html?utm_source=perfectcircuit_youtube&utm_medium=video&utm_campaign=schlappi) modulates and then demodulates a signal with the options of adding lots of odd aliases from the transmission. This patch is sequenced with Noise Engineering modules, the Integra Solum, Mimetic Digitalis and Zularic Repetitior. The Sinc Iter is used as the sound input for the Interstellar Radio to create a noisy snare sound. The Mutable Instruments Stages is used as five envelopes to modulate the bass sound of the Angle Grinder. Intellijel’s Quad VCA is used as VCAs and Mixers and the WMD/SSF DPLR adds a delay effect to the snare sound.
