Ok, this is certainly some horror effect. But: Not that dump as you could imagine for some simple squeaky chair (appearing in your usual movie-fx thing). It is aleatoric and very tweakable (filters, tremolo, reverb, modulation) and, yes lofi. I like it for its unpredictablebilty..
This is really a surprise! You really don't need to think of conches when you play it. It is indeed somewhat meditative, reminds of a recorder / flute / soft reed instrument, and the conches were blown by a musician, who collected them. There is a free version (which I tried here) and a full version, which I probably will buy later. You have lots of otions for tweaking, too. And two .nkis, mono + polyphonic.
Just an appreciation for this. Its name sounds more boring than it is. Easy to use. And its combination of tempo-sync with the resonant filter makes it easy to make it work great on vocals eg. Very easy indeed to create panned panoramic fx. The interface is very simple and selfexplaining. Runs without troubles here on 64-bit Windows in 64-bit Host.
