The Pianocorder Reproducing System is a solenoid-driven player piano retrofit developed by Superscope in the late 1970s (also available factory-installed in the Marantz Reproducing Piano). Instead, the Pianocorder splits the keyboard into two halves, much like the pneumatic reproducing systems of the 1920's, using 5-bit treble and bass intensity values to control the expression. Superscope and QRS jointly created a fairly extensive library of material for the Pianocorder system, available on over 350 40-minute cassette tapes. A large portion of these recordings were made by converting reproducing piano rolls to Pianocorder format.
