(fixes bug no. 1248 - "SAM: some MIDI channels missing on MT-32") This is a very obvious bug if the speech is turned off (otherwise the speech will kind of cover it up). In the SAMNMAX intro it is hardly playing anything. The reason is that the newer sound system has an extra driver layer between the imuse parts and the actual hardware which mananges the channels (similar to what we already do for AdLib, Amiga, FM-Towns...). Whenever the songs are attempting to use a Midi part > 9 our current system will fail. I have written the MT-32 player to also handle the older games music and sound effects. This will allow cleaning up various more hacks in the common sound code. I have done only little cleanup here, since it is not the main purpose of the commit. I will also write a GM driver. This is going to be easier. Currently, there is a only some init and skeleton code for it, the rest is just pass-through...
