The Edirol Super Quartet (HQ-QT1) was a popular high-quality software synthesizer by Roland/Edirol that focused on four core instruments: Piano, Guitar, Bass, and Drums.
However, because this product has been discontinued for several years, finding an official download for version 1.52 can be difficult. Most "high quality" download links found on social media or forums are unofficial and may carry security risks. Official and Alternative Status
Discontinued Status: Roland officially lists the product as discontinued, meaning they no longer sell it or provide direct installer downloads.
Compatibility Issues: The original VST is quite old and often struggles to run on modern 64-bit operating systems without a "bridge" (like jBridge) or specific workarounds.
Legacy Retailers: Sites like zZounds and Musician's Friend still have product pages for it, but they typically list it as "out of stock" or "unavailable". High-Quality Alternatives
If you are looking for the specific sound of the Super Quartet in a modern format, you might consider these safer alternatives:
Soundfonts: Modern repositories like Musical Artifacts host high-quality soundfonts sampled directly from the Super Quartet. These can be used in any modern DAW with a free soundfont player.
Roland Cloud: Roland has updated many of their classic "HQ" series instruments for their Roland Cloud subscription service, which offers much better stability on current Windows and macOS versions. HQ Super Quartet | Software Synth - Roland

Although it has been discontinued by Roland, its legacy remains significant in the history of virtual studio technology (VST). Overview and Historical Significance
Developed by the Edirol division of Roland, the Super Quartet was part of a suite of high-end software synthesizers that included Edirol Orchestral and HyperCanvas. It was designed to provide realistic, sample-based representations of a "quartet" of core band instruments: Piano, Guitar, Bass, and Drums. Internal reverb/chorus: Good but dated – disable and

Instrument Library: Included 60 high-quality presets with variations totaling up to 384 instrument tones and 128 drum kit variations.
Performance: Supported 16-part multitimbrality and up to 128-voice polyphony. Resolution: Capable of up to 24-bit/96kHz resolution.

Some communities have preserved its sounds by creating SoundFonts and sample libraries, such as those found on Musical Artifacts. Key Features Summary
If you have a legal license from 2005 (on a CD-ROM) or a trusted backup, you will need a bit bridge (like jBridge on Windows or 32 Lives on macOS) to run the 32-bit plugin in a 64-bit DAW.
