The resonance of the '485/GX-1 is done in a very odd way, and is a function of 
the harmonic content of the output. There is a trim pot that allows you to 
"tame" this down to a degree. The original VCF was done as cheaply as possible 
using diodes as the control elements. And Sallen-Key filters sound a little odd 
as well.

The GX-1 has limited waveform selection and really not that wide of a tonal 
palette (I call it 'squonky'). Also, the cutoff frequency range of this topology 
is not nearly as wide as OTA-type filters (it's about 100Hz to 8Khz).

But it does sound *completely different* than any other MOTM filter, and that's 
a good thing :)
