Who makes a standalone TB-303-style diode ladder filter?

[dangayle]

Kilohearts has one, but I'm curious what else is out there. Something really squelchy and Acid bassline friendly.

Cytomic's The Drop has a bunch of filters, and one of them is "Cascade circuit topology, BJT ladder core, differential BJT buffers, no explicit resonance limiting circuit, the filter core and buffers do this (eg Prodigy)"

not quite the same, but maybe close enough for what you're looking for

Sugarbytes

Wow2 has a low pass called "030". I believe it is a 3-pole based on the 303.

edit: beaten to the punch by focusrite.

No matter how I use The Drop, it never really does what I think I want it to do. I like it, I use it, but unless I'm doing something wrong, this isn't what I'm looking for.

my apologies, and my condolences. maybe one day Cytomic will add a 303 filter.

Maybe you want a cascade, rather than a ladder?

Maybe this has some interest:

Did you find anything good? You’d think D16 or Audio Realism would make one using their existing code

Diode and ladder filters are some of smoothest,what makes famous 303 sound is distortion after the filter and extreme resonance,diode itself is very clean and 'soft'.
Basically man can experiment with any kind of filters and distort sonic chain after that.
Single filter is just too ordinary and boring,when work in virtual environment - nothing out of the box,which wasn't already done,but if the idea is to copy sound,better use the machine of original sound.
Lately start to use Vital more and think only with filters and distortion it can produce really nice sound...for free
Few months ago i tested almost every free available filters and just few worth attention,quality of most is under pro standard,so if it is for hobby everything is ok,but if wanna make professionally something ,better buy good filters or use lite versions of same.
Impressed by vengence philta cm,minimal audio both lite filters,plugin alliance all free plugins.
Kiloherz free stuff are good too,but only filters can't make amazing sound,definitely each track need right saturation,eq,compression so on to shine.

The sugar bytes filter does fine 303 (it's the filter from their acid synth). Using its envelope follower to modify odd parameters makes it do very weird things. Many of the Melda filters are capable of a crazy amount of sounds. I use Mwobbler as a second filter on synths sometimes. I also use the Zebra filter in zebrify quite a bit and it can do some fun things. Having control of the signal gain into the filter and through the feedback path adds a ton of flexibility in any filter but especially analog style filters. I'm curious what you're doing with this filter. 303s aren't really known for being used to process external audio. I was a bit let down when running drum machines through the filter of a friend's 303. I've had better results with digital filters in general.

Audio Damage Grind has an MS 20 filter that you could prolly do this with. (Legacy version)

Op,asks for a standalone 303 filter , not a 2 pole sallen key filter ( which is what the ms20 is )

If you are using Reaper as a DAW take a look at Filther [JSFX]. The Karlsen Ladder III is inspired by the 303 filter topology.
