I'm really curious about the foldable piano and would love to get some detailed insights on its specifications. Specifically, could you shed some light on whether the keys are weighted? Also, I'm interested in knowing how many octaves it contains and the maximum polyphony available. Additionally, it would be helpful to understand its dimensions and weight. If there are any standout features or unique aspects of the piano that set it apart from others, please let me know. This info will really help me in making an informed decision, so I appreciate your help with this inquiry!
