I am a beatmaker. Teach me how to input MIDI from a hummed melody.

Converting a hummed melody into MIDI data generally involves the following steps:

1. Recording: Record your hummed melody using a high-quality recording device. You can use a smartphone voice recording app or a Digital Audio Workstation (DAW) software on your computer.
2. Audio Import: Import the recorded audio file into your DAW.
3. Pitch Analysis: Some DAWs offer the ability to analyze the pitch from an audio track. Use this feature to get a basic idea of the pitch and rhythm of each note in your humming.
4. Create MIDI Track: Create a new MIDI track within your DAW, and input the MIDI notes based on your pitch analysis.
5. Timing Adjustment: Adjust the position and duration of each MIDI note to match the timing of your recorded humming.
6. Instrument Selection: Select the instrument for the MIDI track and pick the sound that best matches your hummed melody.
7. Fine-tuning: Adjust other MIDI parameters like velocity, expression, and dynamics to make your melody more expressive and realistic.
8. Save & Export: Once you’ve completed all the adjustments, save your project and export it as a MIDI file if needed.

Note that some software offers the functionality to automatically convert audio into MIDI, but the accuracy of such features is usually not perfect, requiring manual adjustments for better results.

These steps serve as a basic guideline, and specific operations can differ depending on the DAW or software you’re using. Nonetheless, this should give you a general idea of the process.
