Information regarding service, upgrade support, and external technical resources for orphaned or proprietary player piano legacy formats.
While modern digital frameworks from Yamaha (Disklavier), QRS (PNOmation), and PianoDisc can be updated with current wireless hardware, certain vintage, proprietary, or short-lived electronic player systems cannot be upgraded or retrofitted using modern components.
We do not provide technical service, parts fabrication, or modern wireless retrofits for legacy proprietary setups, including the early Bösendorfer SE reproducing system or specialized digital platforms from other niche European manufacturers.
The vintage Marantz Pianocorder system (which typically operates via cassette tapes or early digital cartridges) cannot be integrated into modern Bluetooth or Wi-Fi platforms. While Burd and Sons does not service or restore these legacy tape-driven setups, excellent specialized technical documentation, replacement parts, and enthusiast communities exist online. For dedicated troubleshooting and repair advice on these systems, the Pianocorder Forum & Registry serves as the industry’s premier resource.
