Re: BFD filters nothing like predicted response.


Hi there,

I've never used the 1100, but I think it's pretty similar to the 1124. You can select the program you're using by turning the scroll wheel. It should be OK to use any you choose. I happen to use 5.

I'm not sure why you're getting a weird response... See if there's a dot in front of the frequency you set. If so, it will set your filter to be in the kHz range rather than Hz. That might be it, especially if your peaks/dips have moved higher than you'd expect.

When you say "close the filter window and REW erases the filters," I'm not sure. For each measurement in the left hand side, REW maintains filters in the filter window. You shouldn't have to reload. However, if you did a new measurement, the filters will not follow forward. Flip through your various measurements in REW. If you've calculated a filter for that measurement, then it will show up in the "Filters" window.

Using the MIDI connection does make things easier for me. I never have to think about scrolling and setting filter values, especially if I want to do a bunch of quick measurements and tweaks to filters. Of course, once you get the hang of it, it's not really that hard to set the filters by hand, but the MIDI connection does make it a little easier.

Good luck!
