Example for 10*21 grid pattern: (Please note, real patterns are 32*61)

The way to indicate a Dot/Note in each column is simply by the row position. (if no number present then this position is empty). The value 0 is used to indicate a totally empty column. C1 // channel 1 01 02 03 09 10 21 // Column 1 0 // Column 2 03 09 10 21 // Column 3 0 05 21 20 07 10 11 21 0 04 09 10 11 16 17 18 19 21 04 20 // Column 10 *The process is the same for each one of the 4 channels that compose the whole pattern.

Real pattern scheme:

* Please check the music examples below (.SEQ,.MID and .MP3 format) for a better understanding. 
Note: the midi files are not .MID converted to .SEQ but .SEQ converted to .MID (the SEq-Blaster 
program has an export module included). If you want to convert your own SEQ files to MID you 
may set the speed (beats) manually for better results.
