[Bug 47502] New: Wine names MIDI devices not the same as Windows

Bug ID: 47502
           Summary: Wine names MIDI devices not the same as Windows
           Product: Wine
           Version: 4.12.1
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winealsa.drv
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

I'm trying to run Yamaha's DSP controller for AG06 mixer, but it doesn't detect
MIDI device. The reason it can't find it is because it looks for a device named
"AG06/AG03", however Wine transforms the name to "AG06/AG03 - AG06/AG03 MIDI
1".

To make application work I made a quickfix (not for merging, just for my self)
https://github.com/demin-dmitriy/wine/commit/5497db48db29363af332f1f68b2c755...
, and indeed application works smoothly after that.

Yamaha's DSP controller is not the only program that suffers from that. Here's
a reddit post by somebody with exactly the same issue and same solution but
with Rekordbox:

I had a similar problem with a program that uses the MIDI port for data
transfer with an electric piano.

It turned out that the program does not only check the the name but also the
"wVid" and "wPid" fields of the MIDI port.

Having a look at the latest (as of 2021-01-03) version of
"winealsa.drv/midi.c", I found out that only dummy values are returned by Wine.
A comment is saying: "FIXME Product ID".

According to another comment I have found in the sources, it is not possible to
return the same data Windows returns.

My suggestion is to allow overwriting the fields of the "MIDIINCAPS" and
"MIDIOUTCAPS" structures in a registry key so it is possible to run
vendor-specific programs.

Example registry keys:

[HKEY_CURRENT_USER\Software\Wine\Drivers\winealsa.drv\midiinports\EXAMPLE
USB-MIDI MIDI 1]
"dwSupport"=dword:00000001
"wChannelMask"=dword:0000ffff
"wPid"=dword:0000ffff
"wVoices"=dword:00000020

[HKEY_CURRENT_USER\Software\Wine\Drivers\winealsa.drv\midioutports\EXAMPLE
USB-MIDI MIDI 1]
"szPname"="Example Industries MIDI OUT"
"wMid"=dword:00001234
"wPid"=dword:0000ABCD

The registry key name ("EXAMPLE USB-MIDI MIDI 1") would be the name that would
normally be returned by Wine (the name returned by ALSA).

The values inside the key are the values that shall actually be returned in the
MIDIINCAPS and MIDIOUTCAPS structures. For values not specified in the registry
key, Wine should return the "default" (or the correct) values.
