I attempted to do the 02 Round Saw patch from On Your Own and was looking at which filter would best suit.
The Serum lesson pack mentioned that Primer used a Moog style filter. So this leads me to believe that the Monark Filter is the closest matching one. The controls also look very similar.
SVF seems like the second closest but I think that one is a cleaner sort of filter.
I am asking about this because i'm struggling to replicate the sound exactly and considering that maybe its the Synth's Filters that could be like... um... EQing things different (idk the right terms here)
It could also be the Gain knob is effecting things more than a simple volume would. If you attempt this yourself, a Utility Insert Effect for added volume will help.
