hm .. virtually no official information about that: even in the manual it’s just 
“For true HIGHPASS or LOWPASS, make sure the RESONANCE is at zero.”


I don’t have a 904B at hand but just for fun I dared to try the Arturia Modular emulation.
Patching a feedback on the 904B there results in a very vocal type sound when sweeping the frequency.
The useable feedback range itself is very narrow, the VCFs frequency range seems odd too, even without feedback.
But since it’s software it could be virtually anything. ;)
