Do you guys know how to make a 30Hz cut with the heat. purpose is too clean the mud live in the lower registers on the master. Mostly done by my modular. I don´t quite get the information from the manual. The values are all 0-127. Maybe with the LP4 filter ?A bit scared too cut too much.
Why don’t you trust your ears?
I don’t think I have seen any correspondence table between filter cutoff values and frequency domain on this forum.
Time to do it, if you can

all you need is a spectrum analyzer and some noise to figure out what values correspond to what frequency. I usually just adjust cutoffs by ear myself.

Or just buy the shakmat Hipass module, it does wonders, 2hp. You get two additional fixed hipass at 100 to run other stuff through.
It really helps to clean a mix, then the Heat can work on more interesting things !
I know the module. But I mix not in the rack. All different modular voice + other non modular gear goes into a mackie.

Good idea ! Thanks !
Oh ! Makes sense then.
I am still practicing mixing and sometimes its good and sometimes muddy and I try to eliminate all factors that can lend to this. At so low frequencies I am not sure if its too much cut or not or something different is wrong in the mix. If I would be sure : yes, this is a 30hz cut and its still muddy I would know to check other things. But yeah you are right. Need to practice my ears more.

30.87 Hz corresponds to a B0. I’d Play a B0 with a sine, use peak or bandpass with mid/high resonance to find the frequency.

Smart one, buddy.

Ears. I’m using it the same and it’s content dependent. Sampling a lot of vinyl and the sweetspot is btwn 2-4. Resonance has a big part to play, easy to overdo. A smidge.
The most difficult is to find the right B!
Usually 3 possibilities depending on manufacturers.
This B0 is for middle C=C4, A4=440Hz

I usually use that method because I don’t want to turn on a computer.

has anyone figured this out in the meantine?
Or is there a correspondence table out yet?
Would as well really love to bring the Heat to gigs and cut the low freq rumble a bit.
