klingt sehr gut. bedienung der filterverknüpfung manchmal etwas hakelig. wäre schön, wenn man die beiden fikter aufeinen exakten gemeinsamen wert reseten könnte (statt sie da so ungefähr hinzuschieben). klanglich toll, inbes. mit der sättigung.

Unique app

There’s still nothing else on the App Store that does what filterstation does.

The side chain input and the way you can combine it with the other settings is genius

Midi control?

According to the manual CC automation is left up to the DAW.
Great but there's no midi learn feature or list of midi implementation that I could find. Somewhat frustrating.

There’s a lot here to adjust the sound with!

Yes, I don’t feel at all qualified in any way to pronounce on this as I only just started using audio damage apps after iOS 14.2 klutzed them, they are now all working. So, I can say, there’s two blobs attach themselves to separate frequnecies, you then drag these blobs around, and can use the ‘chainlink’ that connects them, to move both at once. It can sound glitchy, or make changes that are like, but not the same as, an EQ adjustment would.

That ‘linked’ adjustment is the graphical part, and the waveform is displayed behind, ghosted in places but in full, and so you see the damage you’ve wrought, or enhancements. Then there are sliders that you can make appear, to make other adjustments to various parameters like ‘attack’ and these two main categories of adjustment combine to give the overall output of whatever you fed in.

Now I just stuck this effect on a basic synth lead sound, but I hanker to shove a guitar signal in there, and fancy that could be a spirited experience.

There, these are my observations, meagre and paltry pickings though they are. It’s capable of a wide range of adjustment, is my takeaway, and now that iOS has gotten over it’s little audio-tantrum, I can start to utilise the apps that got hit by that.

Sounds incredible until it crashes in AUM

Immediately fell in love with this app and the crazy range of sounds that can be intuitively coaxed out of it BUT it constantly crashes in AUM and forces me to restart in order to get any sound to pass through, even when disabling Filterstation2 as an effect.
Again, absolutely love the sounds and the operation but if I can only use it for a minute or two before it forces me to restart AUM (and I’ve had this problem on both iPad and iPhone) there’s definitely something wrong.
