MIDI editor complete explanation?

Hello. I’m new to the BB. I’m loving it so far!

I have dabbled in the midi editor and I have lots and lots of questions. :slightly_smiling_face:
I have searched high and low for resources. I find the same very basic tutorials every time.
Are there some resources that explain what the heck everything is? What are “ticks” and how many should I have in a file, and why do I see vertical red lines running down some midi files? I can hear beats but see no representation of the note. Why?

I would like to see a diagram that explains what everything is in there and what the purpose of it is. Does anything like this exist anywhere? I am anxious to learn as much as I can about the BB, BB Manager software and the midi editor.

I will greatly appreciate any info you can share.

Thank you for reading and for your input,
