"Microsoft GS Wavetable Synth" on Windows 10 not working with midiOutOpen

Hi,

we use the "Microsoft GS Wavetable Synth" through midi port Windows functions in Visual Studio. We have created a little routine to check the availability of "Microsoft GS Wavetable Synth" on Windows 10 which we use it since many years.

Opening the MIDI port=0 which is "Microsoft GS Wavetable Synth" with the Windows function "midiOutOpen" causes an MMSYSERR_ERROR (unspecified error). Below you can find a C++ code snipset we used. This code snipset works fine for XP through Windows 8.1 but on Windows 10, the MIDI port=0 cannot be opened with this procedure. (this procedure was created with VS2010, Win32 and tested on Windows 10 Build 9879)

With regards to the "Microsoft GS Wavetable Synth", we have a few questions:

- will it be part of the delivery of Windows 10 as it was part in former Windows versions?

- will the interface of the Windows midi functions like midiOutOpen supported?

- does VS2010 with its libs work for Windows 10?

Any comments or help is highly appreciated.

Thanks

Reinhold
