MIDI KEYBOARD AND CONTROLLER guide different types

During the late 70’s early 80’s, analog synthesizers manufactured by different brands were using their proprietary standards to synchronize instruments, such as CV/gate, while musicians who chose different synthesizers for their studio set-ups or live performances found difficulty in coordinating their gear with the absence of synchronization. This is when a new protocol called MIDI (Musical Instrument Digital Interface) was introduced by Roland founder Ikutaro Kakehashi, and along with Dave Smith & Sequential Circuit MIDI got implemented in 1983. This standard allowed different instruments to communicate with each other and with computers, and this spurred a rapid expansion of the sales and production of electronic instruments and music software.
