4600/5600 synth: any know more?

It is also HL/LP/BP.  The later version used in the 3600 (LP only, 24db)
uses two 12 db filters in series. This module has to be my favorite VCF it
has great roll off, and as far as I am concerned, a good sound.  I have used
it to drive a sub-woofer before... nothing over about 30 Hz getting though!
Of note, the control portion of this VCF can be used to drive as many
filters as required, if a little creative circuit modification is done.

The VCA's are novel in their design, and can also be used for Ring Mods.
There is a little signal breakthrough at 0v CV, but it's not bad.

The sequencer is pretty good too.
