I wanted a 61 key controller as I only had an older M-Audio 25 key controller, (and 20 year-old Korg X5D) so I got this one based upon reviews here and on other music seller websites. I thought there'd be Midi In/Out but it turned out this was not necessary. The USB cable with a USB A to C adapter worked perfectly with GarageBand on a MacBook Pro as well as a bevy of instrument apps I had on my 2020 iPad Air, which also uses USB-C input. It's light and has a good response.
