I have installed the latest version and applied my license today.
I am just now testing to verify my options for my incoming sound and I plan to try to record a video of me singing and playing guitar.
I am recording directly into VideoPad using a scarlett solo which is plugged into a mac computer through the USB.
I also noticed that if I also plug in my guitar to the scarlett line 2 the audio and guitar are both recorded when creating the video however, the vocal [microphone] is only playing back on the left side and the guitar is only playing on the right.
So, it seems like VideoPad is receiving the audio as line 1 = left and line 2 = right.
I am not sure how to configure this in VideoPad.
