|I can't play a mid file. What should I do?|
mid files are different from regular music files in that they only contain info on how the sound should be generated.
For example, it can be considered as the sheet music for how an orchestral piece should be played rather than the recording of an orchestral performance. GOM Audio requests each instrument to generate the relevant sound according to the sheet music. The data is relayed to the SoundFont (a collection of instruments) where the proper sound is generated and sent to the output device.
As such, output of the audio is possible if the system provides the basic SoundFont. If there isn't any, it is similar to not having an instrument to play, which results in no sound being generated.
Even if there is a SoundFont, it may not have the definitions for all of the instruments, which may result in specific instruments not sounding as it should.
If there are no SoundFonts, connection method is as follows.
If the SoundFont info is output after selection, it is ready to be used.
