MIDI (Musical Instrument Digital Interface) is super important for people who write electronic music. Knowing the main parts of MIDI can really improve how you make music. Let’s break it down:

1. MIDI Messages:

   • There are four main types of MIDI messages:
     • Note On
     • Note Off
     • Control Change (CC)
     • Program Change
   • Each of these messages helps talk to instruments and music software.

2. Channels:

   • MIDI has 16 channels. This helps you control different instruments separately in just one MIDI track.
   • Each channel can create a different sound. This is really important when you are making complex songs.

3. Velocity:

   • Velocity shows how hard a note is played. This affects how loud it sounds and its tone.
   • For example, changing the velocity by just 1 can make a little difference in how the music feels.

4. Pitch Bend and Modulation:

   • You can use pitch bend wheels to change the pitch of notes. This makes it possible to play expressively.
   • Studies show that about 70% of synthesized sounds get better with pitch changes to make things more interesting.

5. Resolution:

   • MIDI works with 128 different velocity values (from 0 to 127) for notes and 14-bit control values. This means there are 16,384 different options for more detailed control over your sounds.

By understanding these parts of MIDI, composers can use it to create expressive and complex music in the electronic genre.
