Further information from nonlinearcircuits:

The Feague is a 4 pole VCF and quadrature oscillator with 0, 90, 180 & 270 degree outputs. It is based on the design in electronotes 41. 

It features a lo/hi switch to run it at audio rates or LFO rates, plus a nonlinear Q pot which makes for interesting behaviour when using as a VCF.  

When using as a QUO, the nonlinQ pot is used to increase the amplitude of the output signal, which is known to shrink somewhat at low frequencies in these kind of oscillators.

Inputs

SIGNAL: audio input 
CV: for controlling cutoff in VCF or frequence in LFO/VCO 
SYNC: sync in/freeze/hold control  
1V/OCT: for controlling cutoff in VCF or frequence in LFO/VCO 

Outputs

Each ouputs are 90 degrees in out of phase : 0, 90, 190 and 270. 
In VCF, the two outputs closest to the side edge of the panel are low-pass outputs, and the other two are band-pass.
