Leploop 12db lp Filter test by val pastel published on 2012-02-16T22:12:56Z some test of the leploop filter - thanks to tonylight for the schematics http://tonylight-leploop.blogspot.com/2012/01/12-db-low-pass-lep-filter.html as you can see, it can be built very small. i used 9v battery. the thing is really strange, when resonance is cranked up. the effect of resonance changes dramatic over the cutoff range. with cutoff closed, there is almost no filtering at all. the more cutoff is opened, the more resonance there is with nasty self oscillation in some settings. i probably should have used a log pot for the cutoff, because it closes really fast. Genre sound demo Comment by lassé des faits Haha i've built 2 of these and both sounded like that. 2012-10-01T17:27:39Z Comment by `▂ ▄ ▅ ▆ JANXEN with an X kabooooooooom 2012-07-15T10:54:54Z Comment by val pastel full resonance 2012-02-17T09:31:12Z Comment by val pastel medium resonance 2012-02-17T09:30:43Z Comment by val pastel no resonance, slowly closing filter 2012-02-17T09:30:18Z Comment by val pastel original Sample 2012-02-17T09:29:07Z
