34 #include "wine/unicode.h"
35 #include "wine/debug.h"
38 * Here's how Windows stores the midiOut mapping information.
40 * Full form (in HKU) is:
42 * [Software\\Microsoft\\Windows\\CurrentVersion\\Multimedia\\MIDIMap] 988836060
43 * "AutoScheme"=dword:00000000
44 * "ConfigureCount"=dword:00000004
45 * "CurrentInstrument"="Wine OSS midi"
46 * "CurrentScheme"="epp"
48 * "UseScheme"=dword:00000000
51 * CurrentInstrument: name of midiOut device to use when UseScheme is 0. Wine uses an extension
52 * of the form #n to link to n'th midiOut device of the system
53 * CurrentScheme: when UseScheme is non null, it's the scheme to use (see below)
55 * UseScheme: trigger for simple/complex mapping
57 * A scheme is defined (in HKLM) as:
59 * [System\\CurrentControlSet\\Control\\MediaProperties\\PrivateProperties\\Midi\\Schemes\\<nameScheme>]
60 * <nameScheme>: one key for each defined scheme (system wide)
61 * under each one of these <nameScheme> keys, there's:
62 * [...\\<nameScheme>\\<idxDevice>]
63 * "Channels"="<bitMask>"
64 * (the default value of this key also refers to the name of the device).
66 * this defines, for each midiOut device (identified by its index in <idxDevice>), which
67 * channels have to be mapped onto it. The <bitMask> defines the channels (from 0 to 15)
68 * will be mapped (mapping occurs for channel <ch> if bit <ch> is set in <bitMask>
70 * Further mapping information can also be defined in:
71 * [System\\CurrentControlSet\\Control\\MediaProperties\\PrivateProperties\\Midi\\Ports\\<nameDevice>\\Instruments\\<idx>]
72 * "Definition"="<.idf file>"
73 * "FriendlyName"="#for .idx file#"
76 * This last part isn't implemented (.idf file support).
