Wow. That looks really painful. I have multiple pianos, always used cable because I wanted it to work without problems in Linux and Mac. Also I can't stand delays.
I have created 20 utils or so with the help of Claude, in order to practice multiple things like reading sheet music, or rhythms, or different scales. I never expected it to be that useful as my new Yamaha was bought before Claude existed, and having a cable that just works is so great.
I have spent way less effort doing all my utils than this man into just connecting its machine.
Before using it with Claude I used them a lot with Synthesia and GarageBand, but with Claude is like having a personal trainer.
