About This Tool
Vintage digital and hybrid synthesizers from the 1980s and 1990s store voice parameters and patch libraries as binary System Exclusive (SysEx) dumps formatted with `.syx` file extensions. Accessing these sound banks typically required obsolete MS-DOS or Windows 98 utility tools or dedicated serial MIDI interfaces. This browser inspector decodes and inspects patch configurations for iconic synthesizer architectures directly in your browser.
### Hardware Synthesizer Architectures The inspector evaluates patch banks across classic hardware synthesis platforms: - **Yamaha DX7 FM Synthesis:** 6-operator frequency modulation engine mapping operator routing algorithms (1 to 32) and operator feedback loops. - **Roland Juno Series:** Digitally controlled analog oscillator (DCO) patches with sub-oscillators, resonant low-pass filters, and analog bucket-brigade stereo chorus settings. - **Korg M1 AI Synthesis:** 16-bit PCM multi-sample waveforms combined with digital multi-effects processing.
### Patch Inspection & JSON Data Export When an architecture is selected, the inspector parses voice bank entries into structured voice records displaying patch numbers, voice names (such as "E.PIANO 1" or "BRASS 1"), algorithm assignments, and operator feedback depths. Selecting any voice isolates its synthesis configuration, while the **Export Decoded JSON** button packages the entire patch array into a clean JSON document for modern software synthesis mapping.
### Worked Preset Inspection Inspecting the default factory bank `DX7_ROM1A_FACTORY.syx`: 1. Select the **Yamaha DX7** architecture button. 2. Select Voice #6: **E.PIANO 1**. 3. The inspector reads Algorithm 5 with Feedback level 6. 4. Clicking **Export Decoded JSON** downloads `DX7_ROM1A_FACTORY-decoded-patches.json` containing all 8 bank voice definitions with id, name, algorithm, and feedback attributes.
### Sound Library Privacy All voice bank parsing, parameter decoding, and JSON file generation execute inside client browser memory. No audio patch files or synthesizer presets are transmitted to external servers.
How to Use
- 1
Choose your synthesizer architecture: Yamaha DX7, Roland Juno, or Korg M1.
- 2
Browse the decoded voice bank table showing patch names, algorithms, and feedback values.
- 3
Click on an individual voice row to inspect its active synthesis parameters.
- 4
Click Export Decoded JSON to download the complete voice library as a structured JSON file.
Frequently Asked Questions
Do I need a physical MIDI interface to inspect SysEx files?
No. The tool parses SysEx patch structures directly in software without requiring physical MIDI DIN cables or USB interfaces.
What data format does the export produce?
The export generates standard JSON containing array objects with voice IDs, alphanumeric patch names, algorithm indexes, and feedback parameters.
Are my proprietary sound patches uploaded to a server?
No. All SysEx parsing and JSON file compilation happen entirely in local browser memory.
