simple answer is…yes (at least on the melodic stuff…there is a mix of colored noise bursts too seperate from the DFS results)
the complicated answer is, to call this thing a filter is to do it a disservice. i would argue that is more of a waveshaper than anything else. the signal is being fed into a 4 bit A/D stage, and then again through shift registers in this really tangled feedback web and it comes out the other end really choppy and sputtery. you can get filter-like effects out of if (sorta) but its not filtering the way one would think traditionally it might. and this is my ‘will it chill?’ attempt…it can go 1000% bat shit crazy, and you can actually lock it up to if you push it hard enough.
…and everything this thing is doing is in turn actually being filtered by a polivoks vcf, which has its own unique grit that its adding.
