@ -481,7 +481,8 @@ The following table provides details on all the settings used by the synthesizer
<li>gs: (default) CC0 becomes the bank number, CC32 is ignored.</li>
<li>xg: CC32 becomes the bank number, CC0 is ignored.</li>
<li>mma: bank is calculated as CC0*128+CC32.</li>
</ul>
</ul>
Note: Drum channels are initialized to \c DRUM_INST_BANK (==128). Since 1.1.7 mma mode also allows the bank of drum channels to be changed the same way as for melodic channels.
