Hi!
I've been using scummvm for a while on my windows server 2008 machine but unfortunately had some trouble using the windows MIDI driver. The problem arising is basically the same as for the Vista people. Scummvm uses the MIDI mapper as default output, while the controls for the MIDI mapper is removed in the os. There are some cumbersome methods to change MIDI mapper routings in Vista, but unfortunately I can't seem to get them to work in WS2008.
This problem can solved really easy in the code though by picking the desired midi output port there. I've written a small proof of concept code, but before I submit a patch I have a couple of questions. If these are better asked somewhere else, please point me in the right direction.
1. In the Wiki there is talk about a music driver redesign. Iis this something that is going to happen soon? If so, where can I find the "new" code so I can write an implementation for it.
2. How should the user be able to pick a desired MIDI device? Using the GUI? Using commandline parameters? Both? My guess is that using the GUI is currently not desired until the new music system is complete.
3. In the MusicPluginObject there is a function called getDevices() which returns all sub-devices for a music driver which is ideal for this purpose. This function does not seem to be used anywhere however, I'm i missing something?
Thanks for any help and thanks for ScummVM!
Window MIDI device selection (Dev question)

Yeah, unfortunately it doesn't work fully in WS2008. And I also can't se how installing third party control panel applets, which globally changes OS behaviour, is easier than having the ability to choose device right in scummvm. Especially since it is trivial to implement and still keep the MIDI mapper behaviour as a default device. This will benefit XP (+ older) users as well.Collector wrote:Google Putzlowitsch's Vista-MIDI Mapper
No, that is not problem. It has probably something to do with differences where the midi mapper information is stored in the registry between the os:es.Collector wrote:I don't know if this is the problem, but if you have 64 bit Windows, it will be in your 32 bit Control Panel.PelleBert wrote:Yeah, unfortunately it doesn't work fully in WS2008.
I don't need any help on getting midi to work on my computer. My point is that there is a simple Windows version-independent way of selecting midi device if it is done inside of the windows MIDI driver in scummvm. But if there is no interest in having this functionality (i can't understand why) then i guess there is no need to complete a public patch.

As i said above, my question is more about how this functionality, if added to scummvm, should be configured by the user. Since I'm new to working with the scummvm code, I have no idea how this type of functionality should be implemented so it best fits.

The patch is applied to the source code, which then has to be compiled into an executable. Of course, if the patch is accepted it will become part of the mainstream version of ScummVM.tareon wrote: Dumb question: How do I (enduser, not dev) use the patch or is this a dev-only thing?
(Since I don't run Windows myself, I have no opinions whatsoever about the patch itself.)
