Extended Play of some of the 2011's BYTEBEAT greatest hits on-a-chip:

How it works
The main module accept parameters from 4x 4-bit parameters buses and generate PWM audio signal on each output pins according to the following bytebeat formulas:
| Pin |
Formula |
Original Params |
out0 |
t*({b,a}&t>>{d,c}) |
a=0xa,b=0x2,c=0xa,d=0x0 |
out1 |
`t |
t%{b,a} |
out2 |
t>>a&b?t>>c:-t>>d |
a=0x6,b=0x1,c=0x5,d=0x4 |
out3 |
`t*(t>>a |
t>>b)&{d,c}` |
out7 |
`t*a&(t>>b) |
t*c&(t>>d)` |
How to test
- Connect a speaker to the pin you want to "play".
- Tweak parameters pins using binary rotary switches.
