- filters with tons of modes tend to be mediocre at most of them with just a few stand outs
- and even if the filter does have more than a few of decent modes, a few modes end up dominating anyway
- filters that implement distortion tend to be a bit honky or scratchy so I end up not using this much
- but, perhaps most importantly, I have yet to encounter an expensive filter that justified its price. I have had many of these and all are sold now. I had decided just to have a bunch of best-in-class single mode filters (I have and have had lots of these)
One reservation: I think this is a filter for people who deeply appreciate filters. At first pass with low-ish resonance the character positions don't sound that different so I could see this being a bit disappointing - particularly at the price - for someone who is looking for a wide variety of easily achievable different filter tones in a single module (as would be provided by e.g. the polaris or ebbe-und-flut on the analogue side, or vult on the digital side). And it's certainly not a set of classic filters in a single package (since the filter sound of classic instruments depends on everything else in the signal path as well). However, this turns out to be a benefit rather than a detriment. Classic filter sounds are the start of the journey with the NF not the destination. And it is the space between these starting points that turns out to be really interesting. For example, a blend between liquid and sour places you firmly into roland space, but it's no roland filter that has ever existed. And when I say filter I should really say filters because even small adjustments in one direction or the other change the response. Most importantly, all of this is extremely playable: provided you set up the poles correctly, these adjustments are extremely smooth and natural. The knobs feel terrific and classy and really contribute to this. This is a very good thing because given that you can modulate character and mode and drive as well as changing poles, well, let's just say you could be at this for a very long time.
For me the NF is to filters what joranalogue's generate 3 is to oscillators: the next level of a concept that has increasingly looked like it might be played out. So, so impressed.
