[sdiy] to opamp buffer or NOT with ota's

[Dan Snazelle]

ok

so having some trouble get clean resonance out of the OTA filters i try and build....everything is coming out very piercing with high Q values

not very smooth sounding.

now...could this be because i am using the INTERNAL buffers of the 13700 instead of using opamps?

do the 13700 buffers even invert?

i see some schematics use em and some dont. just wondering if this could make a difference

thanks
