I feel like I've landed on a realization with my use of envelope filters and bass guitar... And that is that Envelope filters/Low Pass are not as useful as band pass with a clean blend.
Obviously this is just my opinion, YMMV, this is all just us stepping on boxes to make different noises, blah-blah who gives a crap, etc...
It's taken me a while to get here. I had always assumed "for bass, it needs to be a low pass filter"...
...Yet I always keep coming back to the MXR Bass Envelope Filter. I think the opening/closing of a band pass filter is much more "musical" than just the low pass variant. Having the dry signal gives the note enough "heft" in the low end/midrange that you need in a mix without sounding like something has dropped out of the mix, yet you still have the attack of the filter prominent.
I think I probably would like low pass env filters on an actual synth when I can slam the pedal with an aggressive signal.
So I offer this simple post in praise of the humble MXR BEF. It's good enough.
