[sdiy] 2164 SVF sound/noise?

[dan snazelle]

With all the recent threads on the 2164 (and seeing as how i have a few in a drawer) I am very interested in knowing a few things about filters made with them

1. Do they avoid the HISSY nature of OTA SVF filters? (the self noise of an 13700 filter can be quite noticeable with no signal)

2. do they SOUND different? or can you swear you are working with an OTA SVF?

3. how is the resonance


maybe these questions are too general but it sure seems like these chips are all the rage

thanks!
