Elby Designs - 1973 VCF
*EUROSERGE - 4MM BANANA JACKS*
The ES07 is a 2-pole state-variable filter with 12dB/octave slopes on the [LOWPASS] and [HIGHPASS] outputs and a 6dB/octave slope on the [BANDPASS] output.
The ES07 does not self oscillate.
By turning up the [Q] resonance control, the filter can used as a percussion sound generator - xylophone, wood block, drum, bell, gong, vibraphone.
It does not have a 1V/Octave input but does have a scalable [FC CV] input, so can be adjusted to track to play tunes, etc.
See the Patch Of The Week below from Doug for a comparison with the original 1973 VCF.
This is an updated version of the ES07 which now includes the [AUDIO - SUB-SONIC] switch as a panel mount option.
