MIDI production is the most technical but also the most valuable operation in digital audio workstations. It not only requires the operator to have high musical accomplishment, but also requires strong ability to use the software. Such tasks are widely used in film, television, animation, and song creation.

Main hardware participating in the task: MIDI keyboard, PC

Main software participating in the task: Cake walk pro9.0, Midi2wave

Task analysis: Use MIDI keyboard to input the main melody Finally, input the remaining parts; make overall adjustments, adjust the volume, sound and image of each track, and add various effects through MIDI plug-ins. Use MIDI2WAV to convert to WAV music for widespread use.

1. Device connection and settings

1. Connect the MIDI keyboard to the 15-pin MPU401 port on the sound card through the MIDI cable.

2． In the sound control properties, remove the mute option in front of "Synthesizer"; select "line in" in "Playback" to set linear input, and adjust the volume control scale, making sure it is not too high.

3． Set MIDI port. Start Cake walk and set up "MIDI Ports". After selecting the "Options" → "MIDI Device" command in the menu, open the settings dialog box for the MIDI device port.

Note: The MIDI input device on the left side of the window. Generally refers to the sound card. When a MIDI keyboard is connected to the MIDI port of the sound card, when playing the MIDI keyboard, Cake-walk will receive the MIDI keyboard signal transmitted through the sound card. The right side of the window is the MIDI output device. When no external sound source is connected, the MIDI synthesizer that comes with the sound card should be selected as the output device. Otherwise, the MIDI sound will not be heard.

4. Set the music beat. Select the "View" → "Time Signature, Key Signature" command in the menu, double-click the default setting, and the metronome setting dialog box will pop up. This should be set to "4/4 beat, 1 sharp G".

2. Cake Walk Operation

Start Cake Walk. Select the "File" → "New" command in the menu bar to pop up the new file dialog box. Cake walk provides us with many music templates, here we choose "normal". Set the speed. Select "View" → "Speed" in the menu bar to pop up the speed

settings dialog box. "95" should be filled in here. Of course, if the keyboard level is not very high, the speed can be set a little slower. After we finish typing, we can just adjust it to the normal speed.

1. MIDI Main Melody Production

Oh, why haven’t I finished it after talking so much? Don’t panic, the important part begins. Now let’s start making the main melody.

1) Have you seen the audio track window below? Learn to name it first. In the first audio track, double-click the blank space under "Name" and fill in "Main Melody".

2) Double-click in "Source" to open the audio track property settings and set the correct MIDI source. Of course we should choose "MIDI Omni" here. Play the MIDI keyboard to see if the sound and timbre are normal.

3) Officially record MIDI: Press the "R" button indicating recording in the "Main Track" and it will turn red, indicating that this track can be recorded. Call up the rewind button on the transport toolbar, return the music pointer to the starting position, press the record button, and enter the recording state. Don't play in a hurry. At this time, the metronome is beating the beat. When the metronome completes the preparatory beat, the MIDI keyboard starts to be played. When playing, be sure to keep the same beat as the metronome.

4) After playing the main melody, press the stop key in the playback tool. In the window on the right side of the track, you can see the MIDI information of the main melody we just recorded. Then click the "R" button indicating recording in the "Main Audio Track" to return to the original color and cancel the recording. Try playing it to see if it plays well. If you are not satisfied, you can try it again.

2． Main melody modification

Even if you are a good keyboard expert, you cannot guarantee that the score you play is consistent with the music score. It is inevitable that you will play the wrong note and miss the beat.

Therefore, we should also modify the input spectrum.

1) Click the "Main Melody" track, and then click the switch button on the toolbar; or double-click the "Main Melody" track directly to enter the piano roll view.

2) Use the "Pencil" and "Eraser" tools to correct wrong notes in the upper window. "Pencil" adds notes and "Eraser" reduces notes. In the window below, you can use a pencil to adjust the velocity line, and just draw the line directly with a pencil.

3) In this way, the adjusted score is very close to the real score, and there is no need to make precise adjustments, because human ears may not be able to hear it, and even if they hear it, they will not feel it. To what deviation. Select "File" → "Save As" in the menu and name the file as "Main Melody". At this point, the key MIDI keyboard recording of the main melody ends.

3． The operation of the remaining tracks

Mastered the recording and modification of the main melody. The production methods of the other chords, treble parts, bass parts, and percussion parts are all similar. The main purpose is to set the MIDI of each track. Sound source, channel, adjust different intensity, etc. For the same section, you can use the "copy" and "paste" methods to solve it. Due to space constraints, I will not repeat it here. Friends can refer to the relevant books on Cake walk pro9.0.

4. All-round comprehensive adjustment of the music

Each audio track has been basically completed, but the effect when played back is unacceptable and there is no overall sense. Therefore, later adjustments are mainly made from the aspects of volume, sound and image, adding effects, and speed adjustment.

1) Volume and sound image adjustment
