    Anyone know of an envelope filter that can sweep up, down, and not sweep at all (so that it functions as a band pass filter)?

    Yeah I was looking at that pedal, but I don't think it can do the 3rd thing which is to act as a variable low pass filter. i.e., no sweep -- your signal just gets lopped off after a certain specified frequency.

    Moogerfooger MF-101 can act as strictly a lowpass filter, just turn the envelope amount to zero. It doesn't sweep down.

    What about the Maxon AF-9 guys?

    I'm pretty sure the old Ibanez 9 series AF9? does that.

    Both the Maxon and the Ibanez AF9 won't filter down to an E :( Their frequency responses only go to 100hz on the low end.

    The envelope effect is best on the mids only anyways.

  12. Since no one has mentioned it, I will
    The EMMA discumBOBulator can sweep up and down, don't know about flat
  13. the boss ft-2 can do it, plus it has an expression pedal input so you can adjust the freq that it's at in real-time.... like a wah

    I think I'm going to go with the Agent 00Funk Mk II because it has that CV output which would be fun especially plugged into the MF-102. If you turn the sweep knob all the way towards "narrow" I think it'll come close to the flat thing.

    the ebs does up and down as good as any I've tried (except a mutron) don't remember exactly about flat.... I'm sure someone here can set me straight.

    if you turn the sensitivity knob way down on any envelope filter and pluck a certain way so that the envelope doesnt open it sounds close enough to a low pass filter, right?
  17. Typically, it actually is a low pass filter. So, yes. Some EF's also allow you to set the filter to be either low pass, band pass or high pass (i.e. AF-9, meatball...). So, if you turn down the sensitivity so that the envelope doesn't open, there will be no sweep (flat?), and you'll get whichever type of filter you have it set to.
