the Jupiter 8/Juno 106 and KORG DW8000 have some of the most musical-sounding filters ever. I wish the Renoise sampler would have something like one. Metallic self-oscillation would be crazy.

Renoise definitely needs some better stock filters. The current ZDF ones were decent over 10 years ago, but they don’t seem to currently support any internal filter-structure nonlinearities or self-oscillation, which severely limits their serviceability for sounding analog and musical.
Those Roland OTAs are indeed some of the best examples, as well as some of the ladder cascades from the same era. Cytomic’s The Drop is still the gold standard, which is a lot to ask, but that still should be the quality to aim for in current year, with many competitors offering viable options.

Agree about cytomic being the gold standard , Andrew Simper just sets the bar for almost everything ,
I also agree about the renoise filters , the drive ( especially noticeable in the instrument editor ) is always applied post filter and it shapes the amplitude (decay ) curve , which proves it’s just post filter drive
Non linear fiter drive should be part of the internal feedback loop .
That being said the standard clean filter is really good and doesn’t so much different from the gforce sem , the diode is another of my favourites .
The gforce sem filter is amazing at filter FM , and renoise…well let’s not get there 
Renoise is closed software ( and hopefully stays that way ) but there are some great sounding freeware filters some of which are implemented in surge , if these could find their way into renoise .
Renoise is just not getting enough TLC for it’s dsp devices …

I also like the filter FM in Repro. I think Hive’s filters hold up too, and the new ones in Icarus 3 are amazing.
