Does the "Fine Tuning" lamp stay lit, does it flicker or does it stay off? The Pianocorder gets its clock signals and note data from the tape. Missing even one of the clock signals will cause the lamp to light. If this occurs, two correct frames must be received before it will play again.

Do you hear a high pitched squeal from the cassette? Is the tape evenly wound on the hubs? Anything which slows the tape as it goes past the playback head will prevent proper playback.

Have you tried varying the tempo control to see if that makes any difference?

Exercise the Record button on the cassette player as suggested in the next post to the forum. Check that the felt pressure pad in the tape cassette hasn't fallen off. Watch the cassette when you press Play. Be sure that the cassette engages the playback head as it moves forward.

Look for excessive oxide as you clean the heads. That would indicate serious deterioration of the binder which glues the oxide to the mylar.
