This software is an editor / librarian for the YAMAHA DSR-1000 and DSR-2000 synthesizers that allows you to access the deep, hidden architecture of the 4-Operator FM engine.
For decades, the DSR series was often overlooked as an entry level keyboard. However, underneath the hood lies the YM2414 (OPZ) sound chip—the same legendary FM chip found in the Yamaha TX81Z and DX11. While the original hardware limits you to basic "Spectrum" and "Brilliance", and a few more edits, this software unlocks the full potential of the machine, granting you total control over every internal FM register.
Developed through extensive reverse engineering, this editor bypasses the simplified front-panel controls and gives you the surgical precision of a studio-grade synthesizer.
Total Operator Control: Manipulate all 4 operators independently. Access all 8 waveforms (including the famous non-sine waves) to create everything from gritty, aggressive basses to crystalline bells.
Complete Algorithm Access: Choose from all available algorithms to route your operators, moving far beyond the factory-defined presets.
Advanced Envelope Shaping: Fine-tune the multi-stage ADSR envelopes for each operator to create evolving pads and complex percussive textures.
Librarian & Patch Management: Effortlessly save, organize, and bank your custom sounds. The DSR’s limited internal memory is no longer a bottleneck.
Real-Time Tweaking: Experience the tactile joy of sound design with a modern, intuitive interface that brings 1987 technology into the modern studio workflow.
The DSR-2000 is often called the "Sleeper DX11." With its 61 velocity-sensitive keys, pitch/mod wheels, and built-in speakers, it is one of the most unique FM performance instruments ever made. This software is the "missing link" that finally provides the professional editing environment this hardware deserves.
