Still need to prepare

  • keyboard demo?
  • banana demo?
  • color tracker demo?

Bring

  • Amplified speakers
  • Dongle for VGA
  • Laptop and power supply
  • Makey clone
  • PS3eye
  • power strip?

Kick it off

What is Pd?

  • Dataflow or patching language
  • Created by mathematician/violinist: Miller Puckette
  • While Miller can be credited for popularizing the idea of dataflow, Pd itself follows models of other languages intended for sound synth
  • Max/MSP is the big corporate cousin, actually the older brother
  • Open Source/cross platform
  • Pd-vanilla vs. Pd-extended
    • Audio only vs. openGL (Gem) and friends
    • Matrix manipulation (iemmatrix)
    • Physical Modeling library (pmpd)
    • Careful: not everything in Pd follows the Pd-vanilla model. :-/
  • Another alternative: Pd-L2Ork
    • Actively developed
    • Linux only

Overview of Pd-extended:

I will sloppily use the terms 'Pd' and 'Pd-extended' interchangeably unless I don't

Example1: audio

  • Build 'A' with [osc~] and [dac~]
    • Show canvas help, then interactive object help
    • talk about tilde
    • keyboard shortcuts
    • inlets, outlets, creation arguments
  • Add volume control *~, number box
  • line~, snapshot~
    • audio streams (sig~) vs. control
  • bang~
  • add freq slider with line~
  • make a note

Example2: audio

  • audio scratcher
    • arrays
      • use [tabread] and [tabwrite] to show that it really is an array
      • substitute [table]

Example: video

vblank_mode=0 glxgears
  • Hello World video
  • 60 fps (and prove it with toggle, then a counter)
  • [fullscreen 1(
  • add [osc~] and [snapshot~]

Concepts

  • Hot and cold inlets
    • [+ 3]
    • feed one number to 2 [+] objects
  • subpatches
  • abstractions
    • [s] and [r] (and [s~] and [r~])
    • numbers, sliders, etc. getting messages
  • building your own objects in C
  • single threadedness [pd~], and [netsend] [netreceive]
  • cuda

Fun Stuff

  • pmpd (47 scanned synth)
  • interfacing with the arduino and friends
  • dynamic patching: Manuals -> pd-msg -> 1.msg_and_patch -> 1.2 create_patch.pd

Pd in the wild

  • Pd is really 2 separate programs
  • libPd is the sound synthesizer separated from the interface
  • libPd runs on iOS, Android. There's even a book about using it on mobile devices.
  • Pd vanilla is popular on rPi as an open-ended all-inclusive DIY effect box. One example

Examples

  • Steve's stuff

Alternatives to Pd
