I have a Casio Privia PX-100, and a Dell laptop. The electronic piano has a MIDI input-output set, and TWO headphone jacks. The laptop has HDMI, USB, microphone, and headphone inputs/outputs. I am looking to record the SOUND of the piano - NOT MIDI. Two questions:
(1) Do I need a headphone splitter, or may I plug headphones into the remaining jack (while the other one is being used for recording)?
(2) My jack size is 3.5mm (1/8 inch). Will the following product work? Can I get anything better instead? https://www.amazon.com/3-5mm-8-Inch-Stereo-Audio-Cable/dp/B001QDB7R0/ref=pd_sim_23_2?_encoding=UTF8&pd_rd_i=B001QDB7R0&pd_rd_r=QPKJC9BJX6393A47G5GH&pd_rd_w=7zZOk&pd_rd_wg=UrLxN&psc=1&refRID=QPKJC9BJX6393A47G5GH
