2 Problems - PTT Key + "Record to separate track"

[Fish]

I have two problems. First (and least important), I can't use my normal push to talk key. Mirillis doesn't seem to recognize scroll lock as a viable hotkey. Are there any plans to add support at some point?

Second, when I use the "Record microphone into separate audio track" setting, I get NO microphone audio, at all. =/

Are you recording to AVI or MP4?
As far as I know MP4 doesn't support recording the microphone to a separate track.

I have problem with PTT key also after the last update, I was recording mic only when I press a keybinding (CTRL) and it was fine but after the last update it is ignoring this option and record everything.
Any idea?
Thanks.

You could make your push to talk key a key that you never use like... j for example and then bind your regular mic button on the mouse to the j key.
