My project is to harmonize audio output from F-keys with audio from my headset mic. I noticed that audio from F-keys, recorded on the fly, is much lower than the audio directly from mic. I have set monitor level on my IC-7300 to 100% Levels on PC: Main level 100% Mic and Speaker levels 100% N1MM Audio Setup and Monitor: Max on Radio1 Record. I have tested with a local, and there is a big difference. My signal using mic is far louder than the recorded one.
