The MIDI Association has two types of members; Corporate and Individual.
Corporate membership is open to any commercial entity that designs, develops, or produces products that use MIDI technology. This includes platform/OS developers like Apple, Google and Microsoft, and musical instrument and software companies (such as Ableton, Make Music, Mark Of The Unicorn, Native Instruments, Nektar, Roland, Roli, Steinberg, Yamaha, etc.).
Individual membership in the MIDI Association is free to musicians, artists, educators, retail salespeople, DIY/Arduino enthusiasts, DJs, game developers, and sound designers. MIDI Association individual members can download the adopted MIDI specifications, receive the MIDI Message newsletter, access MIDI Association tutorials and webinars and enjoy all the benefits of The MIDI Association, other than those that are exclusive to corporate members.
