It all depends on the Synthesizers and how you want your music to sound. But with the help of MIDI Keyboard, there is no limit of variations in the sound. Using Piano, we can only produce a single type of sound that it already has of its own. The Synthesizer produces Music that gets amplified through the Studio Monitors. Whenever a person presses any key of MIDI Keyboard, data releases from it and passes through the Software which produces the music. Unlike Piano or Digital Keyboards, MIDI Controllers do not have any sound of their own. This is how music is made using MIDI Keyboard. So basically, it is an instrument that transfers the data into already MIDI-enabled devices to produce sounds in a controlled parameter. The full form of MIDI is Musical Instrument Digital Interface.
