Handling MIDI input

[carlo-bramini]

Hello,
I would like to send to WildMidi some MIDI events received by a physical instruments connected to a MIDI port or via USB.
But it seems to me that the library does not provide a function for sending directly MIDI events to the generator. None of the functions exported by the DLL seem to be good for this purpose.
At the moment I implemented a code for opening a MIDI input port and receive the MIDI events on Windows, and this was the easy part.
Now I would like to send to the library those events, like note_on for example, and here I'm blocked.
Have you some suggestions for this problem?

Sincerely.

Hi!
Sorry, post is two years old, but has still no answer.
As far as I understand WildMIDI is a simple software midi player. It should include a core software synthesizer (softsynth) library that can be use with other applications. But actually I really have not found it in the source tree.

Hello,
I did some changes to the library and I implemented the function for sending the events to the synthesizer.
But I remember that it has not been so easy...
Perhaps, this issue could be used as a reminder for adding a new feature in the future.

Absolutely! A clear MIDI interface in wildmidi for the synthesizer would be more valuable than just to have a sequencer.

I did something similar for a CSharp synthesizer library a few years ago and remember it being difficult too.

I also thought of the same thing you mentioned (the MIDI input could also come from programs in the computer; it is not necessarily external, although it can be).
So, I thought you should add a function: int WildMidi_Send(midi*handle,const uint8_t*data,size_t size);
The data is in the raw MIDI format (without timing or anything else; not the MIDI file format), and would be interpreted immediately.
You would then call WildMidi_GetOutput to advance the timing and to receive the output for that time.
In this mode, there is no input file, so it does not have a duration and the output doesn't stop, and seeking will not work.
Another function or option or something else might be needed in order to tell it to use it in this non-file operation mode (WildMidi_Open and WildMidi_OpenBuffer will not be suitable in this mode).
