Use your computer as an instrument.
What is MIDI?.
Basically MIDI are instructions that allow the computer interpret notes. These instructions use inputs, like a keyboard, an electronic drum kit, even a mouse.
How to use MIDI?
First you need a software MIDI-compatible and VST-compatible (Digital audio workstation, DAW).A few DAWs:
- Cubase
- Pro tools
- Ableton
- Flstudio
- Logic(Mac)
- Reason
- Reaper
- Qtractor(Linux)
- Nuendo
- Acid pro
- Sonar
What I can do with MIDI?
A lot, really A LOT. If you find the right VSTs you can emulate instruments like pianos, drums, synths, voices, basses, etc.
Important: remember you are EMULATING, the VSTs won't sound like a real instrument but if don't have a choice they sound great.
Today electronic music use MIDI (95%) and VSTs (synths and frequency modulators mostly).
Personally I use MIDI to create drum patterns (EzDrummer). Really simple but powerful tool.
So if need a drum, a piano or maybe a synth, a MIDI(with VST) is a always a great option.
