The application will be a simple synthesizer application. There will be no virtual midi keyboard support because this is not a practical solution. The app should work like a synthesizer with a connected midi keyboard. So it should be usable with devices like sound cards. The aux output option seems wise for this.
- Using synth via midi api.
- An easy to use synth library.
- To be able to edit the synth settings from the application.
- Output option for effectors and sound cards.
