    摘要： There is disclosed an electronically adaptive player piano roll to magnetic tape formatting system which adapts itself to play the expression music generated from different sources. A plurality of control bits are inserted into vacant or unused bit positions of a prior art time division multiplex frame of musical data encoded, preferably, in a bi-phase mark/space code. The control bits identify the particular type of player piano roll music which has been well known in the prior art, such as a Welte, Ampico or Duo-Art, each of which have different manners of expression for reproducing the playing style of the original artist. During the playback, a circuit is provided for recognizing the control bits and decoding same and automatically varying the split between the bass and treble expression points of the particular source, whether it be the Welte roll, the Duo-Art roll, or the Ampico roll, or any other roll provided the code has been entered during the time the roll is being formatted into the word or frame of the time division multiplexed musical data.
