Why it matters
This objective helps connect Musical Instrument Digital Interface (MIDI) to exam-style questions, flashcards, and revision notes for Representing images, sound and other data.
Quick student answer
What is the main purpose of MIDI?
Direct answer
To store instructions describing musical performance events
Key terms
- MIDI: A system for representing a musical performance using instructions and event messages rather than a complete recording of the sound.
- Event message: A piece of MIDI information that describes a musical event, such as a note starting or stopping, as part of a timed sequence.
Common trap
Confusing MIDI with recorded audio: Explain that MIDI stores event messages and performance instructions; the playback system produces the sound.

- Analogue/digital conversion: Describe the principles of operation of: • an analogue to digital converter (ADC) • a digital to analogue converter (DAC). Know that ADCs are used with analogue sensors. Know that the most common use for a DAC is to convert a digital audio signal to an analogue signal.

- Bitmapped graphics: Explain how bitmaps are represented. Explain the following for bitmaps: • resolution • colour depth • size in pixels. The size of an image is also alternatively sometimes described as the resolution of an image. Size of an image in pixels is width of image in pixels x height of image in pixels. Resolution is expressed as number of dots per inch where a dot is a pixel. Colour depth = number of bits stored for each pixel. Calculate storage requirements for bitmapped images and be aware that bitmap image files may also contain metadata. Ignoring metadata, storage requirements = size in pixels x colour depth where size in pixels is width in pixels x height in pixels. Be familiar with typical metadata. eg width, height, colour depth.

- Vector graphics: Explain how vector graphics represents images using lists of objects. The properties of each geometric object/shape in the vector graphic image are stored as a list. Give examples of typical properties of objects. Use vector graphic primitives to create a simple vector graphic. 70
