Orpho Vollrausch | Vacuum Tube VCO / Noise Generator Eurorack Module

Vollrausch | Vacuum Tube VCO / Noise Generator

The Orpho "Fullrush" is a combination of Tube-VCO and Noise Generator. It is a non-standard VCO module designed primarily as a noise generator. Two Russian military tubes (6SH1P) are used. The noise can be mixed in with a scope controller. When the noise component increases, the frequency of the oscillator varies until it is completely full. If you reduce the noise completely, the pure VCO signal is left over. Due to the "curved" characteristics of the tube oscillator, the module does not have a precisely defined control characteristic (e.g., V / octave). The inevitable tolerances of the tube oscillator will also make each module sound a little different. The tubes can also be replaced by two EF95 or similar. be exchanged, which then sound different again. By applying a control voltage to the CV input, e.g. LFO, sequencer, etc. can be varied in the usual way the sound varied.

  1. One has to know that "Vollrausch" is an intended german pun: It can be interpreted as "complete noise" if your are into synths. But in the normal german it means "drunken stupor".
