If I have used all 16 channels, 1 instrument per channel, and want to add a 17th which is the same as one of the other instruments, how does that work?
I guess its simple enough if they do not play the same note.
But if the 2 instrument in the channel plays the same note, how do I handle that?
How does MIDI software usually solve that?
Do they attempt to increase the note velocity by some dB as to make it double loud to simulate its 2 instruments playing the same note?
If yes, is there a good algorithm for how much to increase the velocity?
