ASM1 filter self oscillation

[John Speth]

I have been experimenting with a VC Q circuit for my ASM1 VCF I found in
Chamberlin's Musical Applications of Microprocessors.  I think this is
right out of Electronotes.  One of my goals is to get the filter to self
oscillate at a high Q setting with no signal input.  I realize that there
is a Q limiter in the feedback path.  So if I take it out, does anybody
know if a state variable filter can self oscillate in a controllable manner
like its' 4 pole LPF conterparts?  Or is there something about this circuit
that makes this impossible?
