Is that the Bluetooth Adapter for iOS ?
It would be the same on iPhone.
The description for that video includes links to the cable you can use to connect your keyboard to an iPhone.
Thanks for your time and the explanation .
i saw that video but is that the same to record a MIDI file via iPhone or I have to use the Mac for that ?
SeeMusic cannot automatically create particles from a video file. You’ll need to also record a MIDI file. Please see this video for help: https://youtu.be/QdZbZW-hO94
