Python midi sequencer

creating a midi sequencer in python can be quite an exciting project! midi (musical instrument digital interface) is a standard protocol for communicating musical information between electronic instruments and computers. in this tutorial, we will use the `mido` library, which is a popular library for handling midi messages in python.

### prerequisites

next, you need to install the `mido` library and a backend for playing midi files. you can use `python-rtmidi` for real-time midi input/output.

to install these libraries, run the following commands:

### basic concepts

1. **midi messages**: midi works with messages that tell devices when to play notes, how loud to play them, and when to stop.
2. **midi files**: midi files are a way to store sequences of midi messages.
3. **midi ports**: these are used to send and receive midi messages to and from midi devices.

### creating a simple midi sequencer

we'll create a simple midi sequencer that can generate a sequence of notes and play them through a midi output.

#### step 1: setting up the midi output

first, we need to set up a midi output port.

#### step 2: define a simple sequence

next, let's define a simple sequence of midi notes. we'll create a sequence that plays a c major scale.

#### step 3: closing the output port

after playing the sequence, make sure to close the output port.

#### complete example

here’s the complete code for the simple midi sequencer:

### running the code

to run the code:

1. make sure you have a midi output device connected (this could be a virtual midi device or a hardware synthesizer).
3. run the script in your terminal:
