OPL3 (YMF262 bug) - 4op patch interrupted by unrelated channel

[James Alan Nguyen]

Channels D10-D12 appear to be interfering with D0104 D0205 D0306 when mixng 4op and 2op patches.

Example:

'{

	TitleName   = YMF262(OPL3) test
	TitleNameJ  =
	GameName    =
	GameNameJ   =
	SystemName  =
	SystemNameJ =
	Composer    =
	ComposerJ   =
	ReleaseDate =
	Converted   =
	Notes       =

}

Disable and enable Line 71 ('D10,12 under Bass) and you will hear a difference in patch tone for the 4op channels (Melody).

Also interesting: setting p1 or p2 after @5 breaks the 4op mode, but placing it before the @5 works OK.

First bug is fixed.

There is still one bug for panning.

Replace Line 62-67 (Melody) with the following:

Melody

'D0104 m1p3@5v127l8o4q1
'D0205 m1p1@5v125l8o4q1D1r16.
'D0306 m1p2@5v123l8o4q1D-1r8.
'D01-03 [d&<a&>d&e&a^^ p1 a&b^^ba^g^f+^b^>c+^d^ p2 <f+e^ddc+de]2

1. Incorrect patch after panning set after 4op instrument (OK if before 4op instrument)
2. Panning command not obeyed.
