Gigatron TTL gtBASIC : bytebeat procedurally generated music, (CROWD).
Fully coded in gtBASIC, it makes maximum use of the Gigatron's new instruction's and sys call's in ROMvX0.
Uses shifts and adds to generate music from math in real-time.
Generates an 8bit waveform and stuffs the generated samples into the Gigatron's audio wave memory around 30 times a second, (60 when the oscilloscope is disabled).
CROWD was originally discovered by kragen, see http://canonical.org/~kragen/bytebeat/
Renders a basic oscilloscope using the new ROMvX0 instructions whilst generating the sound samples.
