I have a Yamaha P45 whose audio I want to record — I use headphones when I practice so I know there is an audio output that's not MIDI. Does anyone know what kind of cables / equipment / software I can use to directly record the audio output of the Yamaha P45 to my laptop live as I am playing? I have looked in the user manual and browsed around online without much success
It sounds like you're just looking to make a quick and dirty recording, without any particular processing. In that case, you just need a cable to go from the keyboard audio out (the headphones plug) to the MacBook's audio in (the microphone plug). From there, you can use any on-board sound recording software, like QuickTime (instructions) or Voice Memos (instructions).
