I guess you can check a few things. As shown in this wiki section are the checkboxes set as explained over there? How is your Yeti Classic Microphone connected? If Bluetooth then that can cause an issue. If USB then it should work, well unless the software of Yeti for this mic isn't playing nice with Equalizer APO.
Whatever you use, Josh, I'll try to support you.
Equalizer APO engine's reads and processes line by line. So in your case this is done by the engine: Config.txt is opened Device HC2 is selected Pre amp on HC2 GraphicEQ on HC2 Microphone file opened Commands in microphone file processed Back to config.txt: Mic device is selected Plugin is done on mic Of course the Microphone file needs a Mic device command in its first line. Or you could put that one before the microphone file in config.txt. Great to hear that you got it working. Btw. I'm the developer...
So i need to put an Include command under the Graphics EQ for the microphone txt file to work in the microphone. Exactly. Or alternatively, above the Device: Headphones Astell&Kern HC2 command. Everything what's beneath a Device: command is done on that device, until another Device: command is encountered by the audio manipulation engine of Equalizer APO) as all commands are sequentially processed. So: Device: A all commands which need to be performed on A (like pre amp, graphicEQ, include, etc.)...
Looking at config.txt I see the microphone won't be manipulated by Microphone (XLR2020).txt as there isn't an include command like this: Include: Microphone (XLR2020).txt
Ok.
I'm not sure about your files. For instance, I see you have included "Microphone.txt" in "Microphone.txt" itself, basically a loop. Perhaps the config.txt screenshot isn't showing it but I don't see the necessary include command. Also, I don't see the microphone selection command in "Microphone.txt" causing the VST plugins be done on all devices, input and output. Although I'm not sure why the VST's aren't working perhaps I should take a look at your files.
That's fine, Josh.
