Musical Instrument Digital Interface

When was the MIDI Spec. 1.0 defined and put into practice?
|
MIDI Spec 1.0 was defined and put into practice in the early 1980s with the discovery of digital vs. analog recording. Though MIDI was simple and limited, it has come a long way in such a short time and completely changed the way music was recorded and produced.
|
What were the main goals put forward by the MIDI Spec. 1.0?
|
The main goals were to be able to send data from one place to another, instead of recorded analog. This could allow musicians, writers, and editors all over the world to work on the same tracks using the same digital data. It was also allowed many different sounds from one or a few controllers which revolutionized the way music has been recorded and edited ever since. Since MIDI Spec 1.0, you don't need a musician for each desired instrument at the same place at the same time (and to resolve synch issues)
|
What does a MIDI thru port do?
|
A MIDI thru port allows another controller to be hooked up to a receiver. The thru port acts as the input port, copying the messages that are transferred there. Completes the circuit and allows for more than 1 controller at a time.
|
What is the function of a MIDI interface?
|
Most computers only have one or two USB ports and a firewire port. A MIDI interface allows several cables and several different types of cables to be plugged into the interface (depending on the size and make of the interface), and the interface or receiver than plugs into the computer so that notes played on controllers can be edited using a sequencer.

The term patch refers to a sound on a synthesizer. How did this term originate?
|
The term patch originated from older equipment that actually called for someone to physically switch cables or "patch" in order to get different sounds. An example are old phone landlines that were controlled by operators that would patch two lines together in order to send and receive sound and have a conversation, synthesizers used (some still do) a similar idea, where band members physically patched to get different sounds . Now patch refers to a sound on a synth, even though actually "patching" has been replaced with motions as simple as clicking a mouse.

What are MIDI note numbers? Give an example.
|
MIDI note numbers tell us what pitch a note is recorded in. The standard numbers are (1-88) with middle cat # 60. Modulators on keyboards allow for a wider range of note numbers, but in general each number corresponds to each black or white key on a standard piano. 0-127 is also used for velocity, so when you open up the list of actions in the sequencer, you can actually see a number and pitch and one for velocity.
