Polivoks Filter Arrives
It sounds awesome! It's not as dirty as I thought it would be based on the description at Analogue Haven. I was expecting something different by the "self-oscillates with a dirty pulse" line. It sounds very similar to my SSM A-105 Doepfer LP filter, but a little edgier. The bandpass output is also pretty edgy, especially at high resonances. Overloading the filter (by using both inputs and turning them up all the way) sounds really cool too; a little more mean sounding that the Frequensteiner can be.
The bipolar attenuator for the one frequency CV input is a really nice touch. I wish the second input had one as well; it has no attenuator.
I did some FM of the filter while it was self-oscillating (no input) and I was very pleased. The Frequensteiner tends to saturate a bit when doing the same thing but the Polivoks stays nice and biting. I will enjoy using this as an extra sine wave source; something that I find the frequensteiner doesn't do as well. When you are really FM'ing the heck of it, it sounds really gritty and dirty, almost like noise (as in white, not "hiss")...very cool. One of my favorite sounds I have discovered so far is to listen to the LP out while the Polivoks is self-oscillating (no audio input) and patch the BP output into the non-attenuated freq CV in. The result is this saw-like sounding hybrid. I wish I had a scope so I could see what it looks like, but it sounds very interesting.
The one downside I have experienced is a personal one. The knobs, while very smooth and easy to turn, are a bit "wobbly". If anyone has a Dual Cyclotron, it's similar to the 3 selector pots which have a slight wobble to them. I've begun to get used to it, but it was a bit disappointing at first. I've noticed that no complaints have come from anyone on the harvestman list or back to Analogue Haven about this on the Polivoks or the Malgorithm so I think I'm being a bit overly anal; something that is not a rare occurrence. ;) I'm sure once I have a few more Harvestman modules in my collection, it won't stand out as much. It of course has no impact on the sound, just my OCD.
All in all, it's an awesome filter and definitely needs to be in your collection, especially if you like having many different filter flavors.
