MIDI-LAB, a Powerful Visual Basic Program for Creating MIDI Music

Creating MIDI music can be a practical challenge. In the past, working with it was difficult and frustrating to all but the most accomplished and determined. Now, however, we are offering a powerful Visual Basic program called MIDI-LAB, that is easy to learn, and instantly rewarding to even the newest users. MIDI-LAB has been developed to give users the ability to quickly create music with a limitless variety of tunes, tempos, speeds, volumes, instruments, rhythms and major scales. This program has a simple, intuitive, and user-friendly interface, which provides a straightforward way to enter musical data with Numbered Musical Notation (NMN) and immediately create MIDI music. The key feature of this program is the digitalization of music input. It vastly simplifies creating, editing, and saving MIDI music. MIDI-LAB can be used virtually anywhere to write music for entertainment, teaching, computer games, and mobile phone ringtones.

💡 Research Summary

The paper presents MIDI‑LAB, a Visual Basic‑based application designed to lower the barrier to creating MIDI music. Its core innovation lies in the use of Numbered Musical Notation (NMN), a simple numeric representation of pitch, octave, and duration, which users type directly into a multi‑line text box. Each line corresponds to a separate MIDI track, allowing the construction of polyphonic pieces without any prior knowledge of traditional staff notation.

MIDI‑LAB’s architecture is straightforward: the front‑end UI is built with Visual Basic, leveraging the Windows Multimedia API (MMSystem) to send short MIDI messages (via midiOutShortMsg) for real‑time playback. The interface is divided into three main sections. The data‑entry pane accepts raw NMN strings; the instrument/tempo/volume panel provides a drop‑down list of the 128 General MIDI instruments, a BPM slider for tempo, and per‑channel volume sliders; and the control bar offers Play, Stop, Save, and Load functions. When the user presses “Play,” the NMN strings are parsed, converted into a sequence of MIDI events, and streamed to the selected output device, delivering immediate auditory feedback.

File handling follows the standard MIDI file (.mid) specification. Upon saving, each track’s event list is wrapped in a proper track chunk, and a header chunk defines format type, track count, and timing resolution, ensuring compatibility with any conventional MIDI sequencer. However, the reverse operation—importing an existing .mid file and converting it back to NMN—is not implemented, limiting the tool to a “write‑only” workflow.

Performance considerations are addressed briefly. Because the program is written in Visual Basic, it benefits from rapid development and tight integration with Windows, but it lacks multi‑core optimization. In scenarios involving many simultaneous tracks or high‑resolution timing, users may notice latency or jitter. Moreover, the Windows‑only nature of the software restricts its accessibility to macOS and Linux users, a notable drawback for cross‑platform development teams.

From an educational perspective, NMN’s numeric simplicity encourages novices to experiment with melody and rhythm while implicitly teaching scale degrees and interval relationships. Real‑time playback reinforces learning through instant auditory verification. Nevertheless, the absence of a visual staff representation means that students cannot see traditional notation, and advanced composers will likely need to export the MIDI file to a full‑featured notation editor for further refinement.

The authors conclude that MIDI‑LAB successfully achieves its goal of providing a low‑cost, user‑friendly environment for rapid MIDI composition, suitable for entertainment, teaching, game soundtracks, and mobile ringtone creation. They propose several avenues for future enhancement: (1) porting the application to a cross‑platform framework such as Electron or JavaScript to reach non‑Windows users; (2) integrating a staff‑based visual editor that synchronizes with NMN input; (3) implementing a bidirectional conversion engine to translate between MIDI and NMN; and (4) optimizing the audio pipeline to reduce latency for complex arrangements. With these improvements, MIDI‑LAB could evolve from a prototype into a robust, widely adopted tool for both beginners and seasoned musicians.
