“MIDI is a technical standard that describes a protocol, digital interface and connectors and allows a wide variety of electronic musical instruments, computers and other related devices to connect and communicate with one another. A single MIDI link can carry up to sixteen channels of information, each of which can be routed to a separate device.”
There’s a misconception about the use of MIDI. It is often referred to describe 8-bit video game sounds, artificial drums etc. But the truth is that MIDI is just a language not a sound.
This language may enable the communication between a tube amp and a DAW such as Cubase. Even between your smart phone and your soft synth inside the DAW.
So, what can this language convey between devices?
