Just I am developing a Windows store app which generates program-inside MIDI files from graphic actions (Picture painting) which should be played then.
Unfortunately, the MediaElement class cannot play MIDI files.
If the transcoding of MIDI to WAVE (or MP3 …) would be possible, then the transcodet WAVE (or MP3) could be played
with MediaElement - but Windows.Media.Transcoder Class cannot transcode MIDI files.
Because the MIDI files are generated program-inside, the WindowsPreview.Devices.Midi API could be an alternative, while the MIDI messages timer-steered are sent directly. As far as I know the WindowsPreview.Devices.Midi API is able to serve only external
(USB-) Devices, not the internal Device (= the sound card, i.e. the software Synthesizer).
At the moment my Windows store app generates in addition to the MIDI file (which cannot be played) a WAVE file which is played with the MediaElement class (this sounds give: Sine plus some overtones instead of real music instruments).
Neither with the MediaElement class nor with Windows.Media.Transcoder Class and also not with the WindowsPreview.Devices.Midi API it is possible to treat MIDI without external synthesizers devices.
This is an untenable state. I hope as well as many other users that Microsoft takes here immediately remedial action.
Yours sincerely
