Introduction
Digital music production relies heavily on tools that allow musicians and enthusiasts to explore ideas quickly and interact with existing compositions effortlessly. Synthesiser is built precisely for this purpose—a lightweight, intuitive, and highly capable MIDI playback tool designed for Windows users of all ages. Whether you are studying musical arrangements, testing MIDI instruments, analyzing note structures, or simply enjoying classic MIDI tunes, Synthesiser provides a smooth, reliable, and enjoyable experience.
With built-in sample MIDIs, dual playback systems, playlist support, an advanced information panel, and a custom MIDI engine, Synthesiser ensures that anyone can play .mid, .midi, and .rmi files without complexity. Its feature-rich design empowers users to customize playback behavior, adjust speed, control volume, switch devices, view lyrics, and handle thousands of files effortlessly. As a portable and open-source tool, Synthesiser offers flexibility for musicians on the go, students in computer-music classes, and hobbyists exploring the beauty of MIDI-based sound.
A Smooth MIDI Playback Experience Designed for Everyone
Simple Interface With Powerful Controls
At its core, Synthesiser is designed to be easy to use. Its layout presents essential controls clearly, giving users immediate access to playback, playlists, progress tracking, and device selection. Even those new to digital music can start playing MIDI files within seconds.
Whether browsing through folders of music or building custom playlists, Synthesiser maintains a smooth navigation experience that matches modern media-player standards while staying lightweight and efficient.
Dual Play Systems for Flexible Organization
Synthesiser includes two primary playback modes:
- Play Folder – Automatically scans a directory and plays available MIDI files
- Play List – Enables users to build, save, load, and edit playlists
This dual system gives users full control over how they organize their MIDI libraries. For those working with large collections, playlist support is especially valuable. Users can easily copy, paste, open, or save .m3u playlists directly inside Synthesiser.
Advanced Playback Tools for Musicians and Hobbyists
Wide Range of Playback Modes
To accommodate different listening preferences and musical uses, Synthesiser offers several playback modes:
- Once – Play a single file once
- Repeat One – Loop a single file
- Repeat All – Loop an entire folder or playlist
- All Once – Play every file a single time
- Random – Shuffle playback
These modes let users shape their listening sessions based on mood, practice goals, or analysis needs.
Speed Adjustment for Music Study
Synthesiser allows playback speed adjustments from 50% to 200%, making it perfect for:
- Slowing down complex passages
- Speed-testing compositions
- Studying instrumental layers
- Practicing instruments at different tempos
Musicians studying challenging solos or orchestral arrangements gain a significant advantage through speed control.
Intro Mode for Quick File Preview
Instead of playing an entire song, users can preview only:
- 2 seconds
- 5 seconds
- 10 seconds
- 30 seconds
This helps users quickly find the melodies they want without loading entire tracks.
Precision Navigation and Smooth Playback
Rewind and Fast-Forward Controls
Users can jump through a piece by:
- 1 second
- 2 seconds
- 5 seconds
- 10 seconds
- 30 seconds
These precise movements are ideal for analyzing transitions, repeating chord progressions, or studying rhythm patterns in MIDI compositions.
Playback Progress Bar
A clickable bar makes it easy to reposition playback. Users can jump forward or backward instantly during study or casual listening.
Auto Fade-In for Seamless Transitions
One major problem in MIDI playback tools is sudden loud notes when rewinding or jumping. Synthesiser solves this with an Auto Fade In feature that smooths transitions and avoids jarring volume spikes.
Device Management and Audio Control
Volume Boost and Mixer Access
Synthesiser includes:
- Volume control
- Boost up to 200%
- One-click access to the Windows Volume Mixer
This gives users fine-grained control over playback loudness across different devices and sound cards.
Up to 10 MIDI Device Outputs
Musicians can switch between different MIDI playback engines connected to their system. This is especially useful for:
- External synthesizers
- Virtual instrument engines
- MIDI-compatible hardware
- SoundFont-based players
Synthesiser makes device switching smooth and immediate, helping users test audio through various setups.
Rich Information Panels for Learning and Analysis
Detailed MIDI Information Panel
Synthesiser provides an in-depth metadata overview of every MIDI file. This may include:
- Track details
- Event information
- Timing structures
- Channel usage
- Instrument mapping
Musicians studying orchestration, arranging, or digital composition benefit greatly from this level of insight.
Device Status and Count Readouts
Users can see:
- How many MIDI devices are active
- Whether the engine is properly connected
- Current playback status
This ensures stability and prevents issues during performance or study sessions.
Scrolling Lyrics Viewer
Some MIDI files contain embedded lyrics. Synthesiser displays these in a scrolling panel, making it a great tool for:
- Singers
- Karaoke usage
- Educational settings
This transforms Synthesiser into a multifunction music player.
Large Library Capacity and Smooth File Handling
Handles Thousands of MIDI Files Effortlessly
Many media players struggle with large playlists, but Synthesiser is built to handle large collections. Users working with archival MIDI libraries or extensive composition folders will find that Synthesiser loads and manages files quickly without performance issues.
Drag-and-Drop Support
Users can simply drag .mid, .midi, or .rmi files into the interface to:
- Play them instantly
- Add them to the playlist
This makes music organization more intuitive.
Native “.m3u” Playlist Support
Users can:
- Open
- Build
- Edit
- Save
- Copy or paste
.m3u playlists directly within the app, making Synthesiser compatible with widely used playlist formats.
Portability, Stability, and Usability
Custom MIDI Engine for Reliable Playback
Unlike generic audio players, Synthesiser features a specially built MIDI engine designed for stability. This ensures:
- Accurate timing
- Reliable looping
- Smooth transitions
- Low latency
This makes Synthesiser ideal for performances, practice, and technical study.
Portable and Lightweight
Synthesiser runs without installation, allowing users to use it on:
- USB drives

Its portability makes it an excellent tool for classrooms, studios, and travel.
