Probability and Random Processes

State machine

Markov chain: a special(?) case of finite state machine

• Markov chain: definition
• (math...)
• Perfectly Random Sampling with Markov Chains

Cellular Automata / Game of Life

Pd examples

• Random process
• Weighted random process
• Markov chain

Data preparation

Overview

1. Getting the data in / parsing
2. Conditioning the data
3. Mapping to synthesis

Numeric preparation

• Scaling / normailzation
• Modulo
• Transpose / shift
• Linear / log / exponential

Possible I/Os

Input

• numeric data (or control data)
  - pre-stored: .txt
  - real-time: OSC, PD input
• audio data
  - pre-stored: sound file
  - real-time: adc in

Output

• MIDI
  - note
  - control messages (to control effects, etc.)
• audio
  - sample data - by some sound synthesis method(s)
  - real-time playback / sound file
