'''X3I''' is a new instrument bank format developed by [[Oerg866]] for use in his [[xm3smps/oerg]] music conversion tool. It is the successor to [[X3V]]. It can contain up to 65535 [[YM2612]] (X3V can just hold 255) instruments formatted according to the [[SMPS]] specifications; additionally, it can store a description for each instrument.

=File Structure=
 
The internal structure of an X3I instrument bank is simple. The first three bytes spell "X3I", the next two bytes specify how many instruments there are in the bank (0 to 65535); after that, the actual instrument table begins, in the following format:
 
{|class="prettytable"
 
! Voice||Description length||Description
 
|-
 
|25 bytes||<center>1 byte</center>||0 to 255 bytes
 
|}
 
 
 
Note: The X3I format was created to eliminate the limit of just 255 instruments.
 
 
 
Opposed to [[YMX]] files, which store instruments in the format used by ''[[Sonic 2]]'', X3I banks store instruments in the format used by all the other Sonic games.
