I am looking for a device to record my piano lessons and then play them back for learning purposes. I have been looking at Sony mini disc player/recorders but it seems that they require that the input captured through a microphone be downloaded to a computer or stereo system and then played back through those devices. Is there a mini disc player/recorder that will record and play back? I want something similar to the old cassette tape player but with better sound quality. Thanks for any help you can give me.
