+ rdfs:comment "Based on variant 2, with two differences. It uses the the technique described by Stilson and Smith to extend the constant-Q range, and the internal sample frequency is doubled, giving a better approximation to the non-linear behaviour at high freqencies. This variant has high Q over the entire frequency range and will oscillate up to above 10 kHz, while the two others show a decreasing Q at high frequencies. This filter is reasonably well tuned, and can be 'played' as a VCO up to at least 5 kHz." .
