very newbie question.
I'm just starting playing with MIDI and digital piano connection. The goal is to let my son use Synthesia or similar software to practice and have fun.
Piano is a Yamaha Arius YDP141, I have a very good notebook and I buy this adapter https://www.amazon.it/PROZOR-Cavo-USB-MIDI-Entrata-Uscita/dp/B01LYU2CFX
I connected them (IN vs OUT and OUT vs IN, then power on piano) but the MIDI-OX just recognize few note ON and few note off, missing several signals (note on and note off, too).
Am I missing anything important?
Thanks in advance
