Audio examples in Sound Controller chapter

Audio examples for most elements of each sound channel would greatly help to understand what it actually does and put it in some hearable perspective, but also present how some parameters will act or feel differently depending on other parameters:

Example 1
Wave duty could be presented using notes C2, C4 and C6 in 1st available duty, then C2,C4,C6 in 2nd etc etc
This way user can easily hear how each of them performs on various octaves, notice how 50% duty sounds full and bassy at C2, and how 12.5% duty sounds thin and squeaky, and how there isn't hearable difference between 2 other duties

Example 2
Sweep could be represented using few intensities and in each direction, repeating over sequence of 2 notes (C6,C3)
This way user can easily notice how slide behaves on different octaves, usually slower on lower

Start by locating the Sound Controller chapter and reviewing how its channel elements and parameters are currently documented. Done means adding useful audio examples for the proposed duty-cycle and sweep cases, with the examples explaining how the parameters sound in context.
