LouD has released a set of YouTube shorts that highlight the USBSID-Pico stereo demos, using mirrored dual-MOS8580 setups. These demos demonstrate the project’s ability to simulate a stereo listening experience from mono SID data.
The USBSID-Pico isn’t true stereo—it mirrors all SID writes to both chips simultaneously. Each chip outputs the same three channels, but one is routed to the left audio channel and the other to the right. This creates a faux stereo effect that widens the soundstage and makes playback feel more immersive.
Let’s dive into all four demos currently online.
1. Hypersonic Lovers – Atlantis & MultiStyle Labs (2025)
This track is a sonic showcase of power, polish, and polish—yes, it’s that smooth. Played via the USBSID-Pico using dual MOS8580 chips in mirrored stereo, Hypersonic Lovers delivers sweeping stereo motion, ultra-defined textures, and a crystal-clear playback that punches well above what traditional SID emulation can offer.
LouD’s setup runs through VICE SDL2, emphasizing separation between channels that enhances each melodic layer. This is no lo-fi C64 hiss; this is high-fidelity SID music that breathes new life into the Atlantis & MultiStyle Labs collab.
2. Coma Light 13 – Oxyron (2012)
Oxyron’s 2012 demo Coma Light 13 may not be new, but hearing it in full stereo through the USBSID-Pico stereo demos gives it a modern edge. The mirrored dual 8580 setup transforms the composition, spreading arpeggios and effects across the stereo field while preserving the aggressive character of the original.
Running the demo through VICE SDL2, LouD proves that older productions can benefit from today’s enhanced SID platforms—bringing a deeper dimension to classic demo scene staples.
3. What Is The Matrix 2 – Censor Design (2024)
Closing out the trio is Censor Design’s What Is The Matrix 2. This demo packs a cinematic SID punch, and when rendered via the USBSID-Pico’s stereo mode, it hits differently. The mirrored output offers a clean spatial separation that gives each instrument its own breathing room.
The futuristic tones and rhythmic effects feel far more dynamic than in mono. It’s a short video, but one that’ll leave you rethinking how SID music can sound in 2025 and beyond.
4. Next Level – Performers (2023)
This stylish production from Performers shows how well the USBSID-Pico handles dynamic and melodic content. With mirrored output sent to dual MOS8580s, each element in Next Level feels bolder, particularly during fast-paced passages.
The faux stereo enhances layering and rhythm without overprocessing the SID’s natural voice. It’s a standout example of how this board upgrades playback for modern SID fans.

LouD’s USBSID-Pico stereo demos demonstrate what’s possible with mirrored SID playback. Though it’s not true stereo, this faux stereo setup using two MOS8580 chips delivers a surprisingly effective upgrade in sound clarity and width.
