What is a midi map ?</A ></H1 ><P >A Midi Map is something that maps midi events in other midi events .</P ><P >This is totally needed if a synthesizer doesn't understand the standard events (that is, if a synthesizer is not General Midi compliant), in this case, a midi map will translate General Midi events in the events that that synthesizer understands.</P ><P >For example you can make a midi map that converts all the <TT CLASS="LITERAL" >Change patch to Bright Piano</TT > events, to <TT CLASS="LITERAL" >Change patch to Trumpet</TT > events, and so when a song tries to play a piano, it will play a trumpet instead.</P ><P >This may sound odd, (why playing a trumpet when the song is made to play a piano ?), but it is very useful. The GM standard specifies that when a midi keyboard receives an event to change patch to <TT CLASS="LITERAL" >0</TT >, it will change the current patch to <TT CLASS="LITERAL" >Grand Piano</TT >, but older synthesizer will change for example to a <TT CLASS="LITERAL" >Electric Guitar</TT > when it receives a <TT CLASS="LITERAL" >0</TT >. This old keyboard, needed to receive a <TT CLASS="LITERAL" >3</TT > (for example) to change to a <TT CLASS="LITERAL" >Piano</TT >. And here comes the midi map in action, changing all <TT CLASS="LITERAL" >change patch to 0</TT > to <TT CLASS="LITERAL" >change patch to 3</TT > and thus really playing the correct instrument when it has to.</P ></DIV ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="deletingacollection.html" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="doineedamidimap.html" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >Deleting a collection</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" > </TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >Do I need a midi map ?</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
