*Tricks, notes, and differences (?) from the usual mod:

*    effects:
        effect dont work the mod way, instead you set what effect you
        want and it keep on until turned off or another effect is 
        enabled.

        this does not apply for one-shot commands like "set volume".

*    size limits:
        instruments and order list (4 bytes per order) must fit in 16KB

        the multibank version has a pattern size limit of 16KB
        no limit on total song size
        
        the single-bank version has a TOTAL size limit of around 12KB
        (instruments, order list, sound effects, and pattern data)

*    pattern speeds:
        every pattern have their own speed setting.
        
*    notes & instruments:
        C-4 00    play instrument 00 at note C-4

        ... 00    play instrument 00 at the last note 
        (or the instrument's internal note)

        C-4 ..    invalid

        ... ..    nothing

*    Pattern end command:
        the end of the pattern is immediate, and the next pattern start 
        playing right after the command (not even one frame later) so 
        normally you should put it on the next line.
