  1. Please tell me it's a middle age father.
    I would like to use Equalizer APO in OBS Studio
    Can you use it?

  2. I'm looking for a PCDJ-like operation of the Equalizer APO with midi-con knobs and pads ... I don't know if it's similar to Equalizer APO and is compatible with midi-con.

    1. I checked a little, but I couldn't find a "similar to Equalizer APO and compatible with midi".
      It is just an idea, but it may be possible if there is a "VST wrapper that can inject midi input".
      If delay ants are acceptable, you may be able to do it with "VST that can communicate between DAWs".
      Neither of them was found, but it seems that there is a higher probability of existing than “similar to Equalizer APO and compatible with midi-con”.
