Before I started taking audio engineering seriously, id often see my friends with their mini keyboards and think, “why don’t they just record on an actual piano? It probably sounds much better.” But I learned they were messing round with MIDI compositions, a set of binary numbers that have been predetermined in your DAW that allow an infinite amount of sounds. It is actually quite incredible when you think about it.
You can make arrangements using every instrument know to man. You can adjust their attack and their release, and everything you can possibly imagine about a certain instrument.
Using Midi can take the capabilities of a home recording studio and turn them into a professional one. They can take an ordinary drum loop and make it into a professional sounding killer beat and if the producer wanted it to, sound like a synth.
Many of my newer productions have encorporated Midi event, many of them having to use different synth sounds as well as replacing acoustic instruments that I don’t have access to such as a piano or violin.
