No channel preset selection while using OmniMIDI or other midi drivers

[0xSYS]

This might be a bug because I tried everything in order to work with the driver.

I apologize for my slow response. This is currently intended -- unless a device initialization file has been specified for that output, you'll have to select presets by entering the bank and patch numbers manually.
See https://github.com/chirs241097/QMidiPlayer/blob/master/doc/SD-80_SD-90_Native.devinit for an example of how device initialization files are structured.
The UI here can definitely be made less confusing. If you have any suggestions in that regard, feel free to drop them here.
