13<P>This program demonstrates the use of the AX, SEQ, SYN, and AXFX libraries. This program uses the Roland GM16 wavetable and standard MIDI files.</P>
14<P><B>Note:</B> The GM16.DLS file was converted using the <font face="Courier New, Courier, mono">DLS1WT</font> tool. The tool is included in the GCN SDK under:</P>

17</BLOCKQUOTE>
18<P>The tool basically converts a standard DLS file into an arbitrary format implemented specifically for the AX application libraries. Full source code for the tool is provided. Please refer to the &quot;AX Applications&quot; document for more details on the SEQ library and DLS1WT file conversion.</P>
19<P>The Roland wavetable is also included in the SDK:</P>
