    This thread is to, hopefully, help those of us that do not have a firm grasp on filters and how to use them. Too often filters are discussed in terms of audio wave forms and although I understand that this is the correct terminology (ok, I don't really but I am told it is) it would be very very helpful to have filters explained in a (setting) = (effect) manner.

    I will start off with an example of Washout:

    These are some posts from the XSimulator Discord server that may help to better understand washout.

    What do you want to do?

    Insecta Tech - The Roach02/04/2020
    lower EMALP to make it more responsive and increase EMAHP to slow the return(edited)

    First create a EMALP filter and change it to 50, then add a second filter on top of this for EMAHP and range that one to 500 and you'll see what I mean.HANNIBAL02/05/2020
    thanks.. ill try it out!!!! nice!

    I had not thought of upping the high pass filter to 500. For some reason I thought of it as a percentage with 100 being the highest possible. Thanks @Insecta Tech - The Roach for the tip.

    You're welcome

    Here is what I have learned (which is not much): I set the low pass filter higher to get the return to slow down. Higher LP = Slower movement. (I will freely admit that I do not understand what the HP filter does). My final filter settings for DCS is LP=200 HP=500 (EM)

    EDIT: Here is a screenshot showing how I set it up.

    To avoid confusion it would help to be clear about what filters are being discussed, so as to not have SimTools newbies scratching their heads and asking questions about missing SimTools filter fields ;)

    Edited the title as likely to turn up in a search on 'filters', where newbies could easily miss the thread section.
