020- What is "old Apple" sound and how is it produced?
All Apple II computers can produce "Old Apple" sound without any special
boards or add-ons. The system BEEP you hear upon a Reset is an example.
The sound is produced by code which addresses memory location $C030. Each
time $C030 is referenced the output of a flip-flop going to a simple audio
amplfier stage changes state.
For example, in BASIC, X= PEEK(49200) will produce a single click. In
machine code, so would AD 30 C0 (Load Accum from address $C030). Duration and
Frequency of sound can be set by placing the address reference instruction
inside a loop and using other loops to control speed of references.
Although the signal going to the internal amplifier is always a square
wave, creative coding by music enthusiasts, game developers, and other users has
produced remarkable effects ranging from two-voiced music and game sounds to
speech.

021- What is a good source for .WAV and .BNK files?
Have a look on Ground at ...
http://www.apple2.org.za/mirrors/ground.icaen.uiowa.edu/apple16/Music/ .
You should find a couple of different custom made instrument banks for
MIDIsynth. A few to look for: 'Europe.bnk', MIDI.bnk', 'InstF.bnk', 'InstA.bnk',
'GrandPiano.bnk', 'Jazz.bnk', 'MT32.bnk'.
And check TFFE: ftp://apple2.tffenterprises.com/pub/apple2/music/ .
Another good source is commercial IIgs sound software from the What is the
IIgs? site at ...
