1. Sequencing Systems & Techniques MIDI Setup

2. Learning Outcomes Define 2 or more examples of MIDI CC data and explain their purpose. Setup a computer and peripheral MIDI hardware to record both audio and MIDI into a DAW program. Explain the terminology associated with music sequencing techniques through research activity / quiz.

3. MIDI Musical Instrument Digital Interface. A technical standard for a variety of electronic musical instruments. Allows instruments to communicate, control and synchroniser with each other. Standardised in 1983. Revised in 1991 Prior to MIDI? Control Voltage (CV) and Gate or play very precisely!

4. MIDI Data - Types Note Length (Note on / Note off) Note Pitch. Note Velocity. Continuous Control (CC) Data. All MIDI messages include a channel number A single MIDI connection can carry 16 channels of information. Why might this be useful? Find examples of MIDI CC data online.

5. Computer Language MIDI messages are 8-bit (Bit = Binary Digit) Each binary digit has 2 possible values… 0 or 1 8 bit = 2 8 = 256 possible values (0 – 255) (-128 – 127) 1 bit = 2 1 = 2 2 bit = 2 2 = 4 3 bit = 2 3 = 8 4 bit = 2 4 = 16 5 bit = 2 5 = 32

6. 2 x 4 bit = 8 bit The first 4 bits of a MIDI message are used to for a command (Note on, Pitch bend, etc). The last 4 bits of a MIDI message are used to allocate the message to the channel where it is being sent (1 – 16). Thus, each MIDI message can have 128 (256 ÷ 2 = 128 possible values on up to 16 channels

8. MIDI Connections 5 Pin DIN MIDI data travels 1 way The modern solution! MIDI data flows IN and OUT

9. Key USB / Firewire USB / MIDI Audio Jack
