Only plain text and emojis can be input as comments in the player meaning images, gifs, sound clips, and all other media types cannot be left as feedback.
NOTE:
Emojis are filtered out when downloading comments as they corrupt MIDI files and cannot be displayed on DAW timelines.
Q: Can I add a hyperlink in a comment?
A: The hyperlink will not be clickable, but you can add the URL link which could be copied and pasted into a web browser
