this is a fully featured and intuitive pattern state variable filter and trem with joystick control and every bell and whistle you can imagine like tempo sync and level driven filter and amp envelopes, but it falls down because the filter models are not superb and on a lot of sources they sound downright bad. There can be some delay in them too and there's definitely aliasing with extreme pattern and high resonances. On the other hand you really can drive like any parameter with the pattern GUI or automate random controls.... I have a love hate relationship with this effect. Its a lower CPU hit than either Wow filter.... eh, I use it sometimes, lets just say that.
