Today even a 100$ music keyboard might be protected against polarity inversions. As for your digital piano, I'm not sure, but connectors being connected the wrong way isn't something that rare (rule rather than exception). If the chip is powered by your PC USB interface, I don't see why it would damage your motherboard if at the other end you wrongly connect it. Previously those USB options had latency issues, I don't know if it still is the case.Īs for damaging devices by wrongly connecting. You can try another or try the card option, you may have better luck.
Particularly if your Windows initial drivers aren't enough. I don't personally trust converters of the sort MIDI-USB. How old is your digital piano? I am saying this because USB is here to stay, it is a general interface unlike the initial MIDI connectors.
