Protracker...

I was busy studying this subject here in my spare time...
Questions arose:

Are there people here who know this program well?
If so, then I would like to know what the parameters are in the editing mode
tools in more detail than in the description that was included
with the program. There they were simply numbered, but there was nothing about the effects that they impart. Some are already clear; Noise, volume, and the rest
it’s unknown what they’re doing.
And not everything is clear about special commands like “Portamento”, etc. I’m not asking how to change
speed (via B.-.-.08, for example). What about the rest? Does
anyone have a more detailed and clear description or not?
If anyone is interested, I invite you to the soap. :)
You can also use the Internet...
