Hi, I have recently received several hundred .mid and .kar files and after doing some research on the net, this is my understanding. If I have misunderstood something, I would appreciate known what is the correct interpretation. The reason for wanting to understand this is that I would like to perform with my guitar and would like to have some backing tracks to help in the background with drums and other instruments. However, I am deeply disappointment at the quality of the sound of both the mid and kar files and wonder if there is a way to make the instruments sound more realistic instead of toy like instruments.
Here is my understanding;
Midi files are created similar to a computer program in that it creates commands to sound like a particular instrument, the length of time a note should be pressed, etc. etc. but it does not record the actual sound. The sound is generated by a sound card inside my computer and thus it makes the sound called for by the midi file.
Kar files are created the same way except they have an additional option which allows for the video display.
In other words, neither the Mid or Kar files store real instruments. Now, is there a way for me to make the sounds sound like real instruments using my computer? If not, why are these formats so popular when the sound is so inferior to real instruments. It could be that a software program might do that but I'm not familiar with any. Lastly, is there a place that sells backing tracks created with real instruments. Thank you for helping me understand this.
