That allows you to expand the band till it covers the whole spectrum or conversely narrow it instead of moving the center of the band? Anyone have any ideas how to accomplish this in reason 4?

Automate an EQ to do this? Should a bandpass filter with a Q control allow this?

don't know about reason, but i would imagine that just taking a parametric EQ and automating both a lowpass and highpass and their Q's at the same time would accomplish this

simplon from fabfilter has a low cut and a high cut, which is what you are looking for, not really a bandpass.

Yeah I thought about the EQ thing but that's not very precise. Hadn't thought about just doing a low/high pass combo, feel dumb for not thinking of it. Thanks!

I wanna say that such a beast is called a Dynamic All-Pass, but can't find any plugs that fall in that category. Seems to apply more to phase issues as well...

W/ the combined lo/hi pass make sure you're running them in parallel, i.e. the dry signal goes into each filter discretely and are summed at the end.

Filtershaper3 is in beta right now and if you buy it now (version 2) you get the upgrade to 3 for free. I guarantee this would be able to handle that (and a lot, lot more.)

Dynamic All-Pass? I've never heard of "Dynamic" All-Pass, but as far as I know, all-pass filters ALWAYS pass the whole frequency spectrum untouched, and what they do is they change the phase between frequencies. He wanted to have a really wide bandpass filter, which obviously cuts some of the frequencies off, so why are you bringing an all-pass filter to the conversation?

And you said for combined lowpass and highpass you have to run them in parallel. No. You have to run them in series.
By the way, I literally started writing equations in LaTeX to prove it, but when I was in just half I felt it isn't worth it.

What difference would it make if they're in parallel or in series?

Because if they're run in parallel, the frequencies that would be passed are only half the amount that are intended to be passed, because one filter is cutting out those frequencies as the other one is passing them through. If run in series, all the frequencies that are intended to be passed actually do get passed

Thanks for the links guys. I think the high/low pass combo would definitely have to be in series to get the effect I'm looking for.
