Ultra-Rare Vintage Roland WS-1 Writing Switch / Programmer for the legendary Roland CR-78 CompuRhythm!This is an incredibly clean, collector-grade example of the original hardware programmer required to unlock custom pattern creation and step programming on your CR-78.

Condition: Excellent aesthetic condition. The chassis is super clean, text is crisp, and the original cables still look excellent.

Power & Care: The 9V battery has been removed for storage to guarantee zero battery leakage or corrosion damage.

Packaging: Includes the highly sought-after original Roland factory box.

Functionality: Unit is being sold in fully working order.

Perfect for studio use or completing a museum-grade vintage Roland system setup. Safe, tracked, and fully insured international shipping from Sweden!
