 | |
|  * This effect acts like a waveform monitor on each line.
 | |
|  * It was originally done by deflecting the electron beam on a monitor using
 | |
|  * additional electromagnets on the yoke of a b/w CRT. 
 | |
|  * Here it is emulated digitally.
 | |
| 
 | |
|  * Experimaental tapes were made with this system by Bill and 
 | |
|  * Louise Etra and Woody and Steina Vasulka
 | |
| 
 | |
|  * The line spacing can be controlled using the 1 and 2 Keys.
 | |
|  * The gain is controlled using the 3 and 4 keys.
 | |
|  * The update rate is controlled using the 0 and - keys.
