Modern Sampling: High-quality versions of the soundfont, such as the Edirol SD-90 Pack I, feature every note sampled to ensure realistic playback across the entire keyboard range.

File Size: Because of this "every-note" sampling technique, uncompressed versions can exceed 5 GB in size.

Legacy Sound: It is a favorite for creators of "Touhou-style" arrangements or retro-MIDI compositions, as it captures the specific "lo-fi" yet professional sheen of early-2000s Roland hardware. Implementation

To use this soundfont, you need a software MIDI synthesizer or "Soundfont Player" (such as Sforzando, FluidSynth, or VirtualMIDISynth) that can load .sf2 files. While the original hardware required specific drivers for modern OS versions, the soundfont version allows these classic tones to be used directly in any modern DAW (Digital Audio Workstation) without hardware constraints.

To use Edirol SD-90 sounds without the original hardware, you must use SoundFonts (.sf2 files) that consist of high-quality samples recorded directly from the unit. This module is highly sought after by composers (notably ZUN for the Touhou Project) for its distinct orchestral and synth patches. 1. Locate the SoundFont Files

Since the Edirol SD-90 is a discontinued hardware unit, its sound library is primarily preserved through community-made sample packs.

Edirol SD-90 Pack I (Complete): A massive library (approx. 5.46 GB) containing heavily sampled instruments from the original hardware, including the "Bully Set" and "Power Kit".

Edirol SD-90 Pack II: A supplemental collection of 7 instruments including "Viola 2 vib," "Br.Bone vib," and "Classic oboe".

Specific Instrument Patches: Smaller, focused files like the Blow Tenor (sax) and the D.L.A. Pad are also available for individual download.

Where to Download: These are hosted on platforms like Musical Artifacts and Internet Archive. 2. Required Software (Player)

You need a "player" or virtual instrument plugin to load these .sf2 files into your music software (DAW).

Free Players: Use the sforzando player (loads SF2/SFZ) or the FL Studio Soundfont Player.

DAW Compatibility: Most modern DAWs like FL Studio, Cubase, and Ableton support these via third-party plugins.

Notation & Games: You can also use these sounds in MuseScore for sheet music or Synthesia for piano tutorials. SoundFonts - MuseScore Studio Handbook The Edirol SD-90 Studio Canvas Go to product

Title: The Chameleon of Zeroes and Ones: Deconstructing the Edirol SD-90’s SoundFont Capability and its Legacy in Sample-Based Synthesis

Abstract: The Edirol SD-90, released by Roland’s then-subsidiary Edirol in the early 2000s, remains one of the most enigmatic devices in the history of computer-based audio production. Marketed primarily as a high-end USB audio interface and a 128-voice General MIDI 2 (GM2) sound module, the SD-90 harbored a secret weapon: a native, hardware-accelerated SoundFont engine. This paper argues that while the SD-90’s native synthesis engine was competent, its ability to load and play external SoundFonts (.SF2) transformed it from a mere ROMpler into a hybrid synthesizer. By examining the technical architecture, the limitations of its DSP, the workflow integration with legacy operating systems, and its cult status among 2000s soundtrack composers, we uncover why the SD-90 remains a relevant, if flawed, artifact for sample-based sound design.

The Cons:

Loss of real-time control: A SoundFont of the SD-90 is a static sample map. You lose filter sweeps, envelope adjustments, and the TSD effects. It’s a photograph, not the camera.
Large file size: A full GM2 sound set from the SD-90, sampled properly, would exceed 2 GB. Most "SD-90 SoundFonts" you find are compressed or missing articulations.
Legality: Roland has never authorized these conversions. Distributing them violates the hardware’s EULA.

2. Technical Architecture: The Dual-Engine Design

To understand the SD-90’s SoundFont implementation, one must first separate its two audio personalities.

2.1 The Native GS/GM2 Engine The core of the SD-90 was based on Roland’s extended GS format (General Standard), which superseded GM and rivaled Yamaha’s XG. It contained 1,114 tones, 42 drum kits, and a comprehensive effects suite (reverb, chorus, and a 3-band compressor). This engine was pristine, clinical, and distinctly "Roland" — perfect for pop and television scoring.

2.2 The SoundFont Subsystem The SD-90 supported SoundFont 2.0 and 2.1 specifications. Critically, it did not sample in real-time; rather, it allowed users to load pre-existing .SF2 files into its volatile RAM (upgradable to 512MB, though practically limited to 256MB due to addressing).

Loading Mechanism: Via a Windows 9x/XP utility, the user would flush the native ROM’s instrument mapping for specific MIDI channels and replace it with the SoundFont map.
Voice Allocation: The SD-90 had 128 voices shared between the native engine and the SoundFont engine. If you loaded a complex piano SoundFont using 64 voices, the GM2 engine had 64 left. This was a source of contention—unlike a dedicated E-mu or Creative hardware sampler, there was no separate voice pool.

3. Sound Generation vs. Soundfonts

A common point of confusion regarding the SD-90 is its compatibility with Soundfonts (.sf2).

Clarification of Architecture:

Soundfont Compatibility: The Edirol SD-90 cannot load external Soundfont files (.sf2) into its internal memory. It is a ROMpler (Read-Only Memory sampler). The sounds are burned into the hardware chips at the factory.
Comparison to Soundfonts: While it does not load .sf2 files, the SD-90’s internal sound set is vastly superior to most Soundfonts available during its release era. While a typical Soundfont might use 4MB to 16MB of compressed samples, the SD-90 utilizes a 32MB wave ROM derived from Roland’s professional XV synthesizer line, offering higher fidelity, better dynamic layers, and smoother note transitions.

The "Roland Sound Canvas" Sound: Instead of Soundfonts, the SD-90 uses the GS Format. This is Roland’s proprietary extension of General MIDI. It includes:

Capital Tones: High-quality main instruments (Pianos, Strings, Guitars).
Variation Tones: Hundreds of alternate instruments accessible via Control Change (CC) messages or SysEx.
Drum Kits: Over 9 different drum sets, including Standard, Jazz, Brush, Orchestra, and various electronic kits.

7. Conclusion: The Last Hardware SoundFont Player

The Edirol SD-90 represents the final evolutionary stage of the hardware sampler before software samplers like Kontakt and HALion became ubiquitous. Its SoundFont capability was a Trojan horse—allowing a professional audio interface to masquerade as a limitless sampling workstation.

However, the device was flawed. Its memory management was brittle; its driver support was abandoned; and its reliance on the legacy SoundFont format (which lacked disk streaming) meant it could never compete with modern samplers. Yet, for a brief window between 2002 and 2005, the SD-90 offered the best of both worlds: the sound of Roland and the freedom of user samples.

The SD-90’s ultimate lesson is that "obsolete" does not mean "silent." For those willing to maintain vintage PCs, the chameleon-like ability of the SD-90 to transform itself via a .SF2 file remains a uniquely tactile and satisfying method of sound design—a final bow for the hardware SoundFont player.
