Audio interface so that I can put everything onto the computer and I can hear everything back.
Drum machine with Midi keyboard as it is a useful piece of technology to have two in one. A drum machine is good for creating hip-hop drum beats.
DAW, preferably Logic Pro X or Ableton so I can actually create music and have good sounds. I will also be able to create more than just one genre.
Microphone so I can have acoustic instruments as well as electric, which means I can make different styles of music. Also for a vocalist to come in.
Headphones so that I can hear it all in a good sound, and I could hear stereo audio.
