First Recording Device:

Phonautograph:

Invented in 1857, Edouard-Leon Scott de Martinville invented the phonautograph, the first device to record sound. it used a membrane (which vibrated in response to sound.) attached to a pen, which traced a line roughly corresponding to the sounds waveform onto a roll of paper. although  able to record sound, this machine was unable to immediately play back the recording. however   in one experiment it was recorded onto a metal plate which was then able to be played back. 


Issues with this technology:


Photography, was still in its infancy, improvements to this inventions were required in order to make it as a sound recording and reproduction medium.

MOAR MIDI... :P

Midi.... well a midi cable is designed to transport digital bytes (128). with this 0 is counted a number so the volume can be expressed as 0-127.

this means that the maximum amount of data that can flow through at once is 128 bytes. Of course now most midi controllers are connected via usb 'which allows a lot more traffic' but midi still only allows 128, it has been this way from the very beginning. (hence the earlier reference about midi surviving the ages.)

Midi... The platform that survived!

                                  Midi: Musical instrument digital interface.






Midi is the standard electronic language 'spoken' between electronic instruments and the computerized devices which control them during performances. Developed in the early 1980s, MIDI technology allows a keyboardist to kick off a drum synthesizer with one key or a computer to store a sequence of composed notes as a MIDIfile, for example. The keyboard, drum synthesizer and computer all recognize the same set of binary code instructions.


Brief history:


Before midi in the early 1970's electronic musical devices were becoming increasingly common and affordable although there was no compatibility between manufacturers. 


In 1981, Dave smith(an audio engineer) proposed  digital standard for musical instruments at the Audio Engineering Society show in New York. By the time of the January, 1983 Winter NAMM Show, Smith was able to demonstrate a MIDI connection between his Prophet 600 (a later version of the groundbreaking Prophet 5 analog synthesizer) and a Roland JP-6. The MIDI Specification 1.0 was published in August 1983. 


MIDI brought an unprecedented state of compatibility which revolutionized the market by ridding musicians of the need for excessive hardware. In the early 1980s, MIDI was a major factor in bringing an end to the "wall of synthesizers" phenomenon in progressive rock band concerts, when keyboard performers were often hidden behind huge banks of analog synthesizers and electric pianos. Following the advent of MIDI, many synthesizers were released in rack-mount versions, which meant that keyboardists could control many different instruments (e.g., synthesizers) from a single keyboard.
