Kevin Nozari- Moving Colorful Spheres

Moving Colorful Spheres

The link above is the patch that I created which involves 3 colorful spheres moving in different directions. While messing with the patch, you can see that you are able to turn on and off the lighting of the window. Also you can also see that you are able to turn on the moving spheres by either clicking on the “bang” buttons and/or clicking on a specific key. If you are interested on giving the patch a whirl, feel free to download it and let it rip!

Mitchell Crow, Austin Crane, Noal Andersen – Audio Patches

Here were a couple audio patches I threw together over the weekend. The first patch is an example of AM sythesis using the computers microphone and an sine carrier wave that can be adjusted. It’s pretty need to listen to the effect, especially when you whistle. It also has plots so you can see what’s happening with the waveform.

AM Synthesis

The second patch is another audio patch that takes user input from the keyboard and plays the corresponding midi note for a particular keystroke. I’ve also incorporated an envelope to give a more preferred sound when attacking and releasing a note rather than the immediate attack and immediate stop otherwise. I’ve got a very musical background and have a decent amount of experience in audio engineering so hopefully I can share some of that knowledge with the student and this is a great example of why we have envelope filters.

Fun with Enveloped Keystrokes

I could easily combine these two projects to have the keystroke generated pitches be AM synthesized by a specific frequency and may put together another patch doing that tomorrow before we meet the students.

Austin Crane and Team!

I started playing more with some of the example patches that are in the “apple” section of the help tutorials and found one that i think would be cool to show off because i think it could be a cool way to play music with using the trackpad. If i knew more on how to use PD i would like to have it play a different tone depending how many fingers i have on the keypad, where they are on the keypad, and how fast i touch and let go. I think this will inspire the students to play with different ways to use the technology to get cooler sounds.

you can personally use this patch if you go under help/pd_help_browser/apple/examples/trackfivefingers.pd

Space Command Central – Video & Audio Recorder


It’s nice to rip videos for the video scratcher, but I thought it might be more fun to make our own videos. This Video/Audio recorder will record video and audio files that the video scratcher can use. It’s pretty basic, nothing fancy. Just records and plays back videos. Tested on Win7 only so far. I’d call it “alpha” quality: if your computer blows up half your house using this patch, I claim no responsibility.

To use:

  • if you need, choose the webcam you will use with the [device( message
  • click on the “bang” to choose a base filename. Don’t add an extension.
  • set your audio record level if you need with the vertical slider.
  • record, playback, re-record, etc. until you get what you want.
  • 2 files will be saved: an mp4 and a wav. These will load right into the scratcher.

Space Command Central – Video Scratcher

Enter Team Space Command Central with a simple video scratcher.

Scratchity Scratch Scratch and welcome to 1991.

To use this patch, you next a video to scratch through. You’ll have to separate the audio out of the video into a separate file and make sure the video is of a format Pd can read. A how-to for youtube videos is here. Name the video and audio files the same basename so only the extensions are different (example: myGreatVideo.mp4 and myGreatVideo.wav). Put them in the same directory.

Once you have a video to play with:

  • Open the patch and click on the “open file” bang button to choose a video. You can click on either  the mp4 or wav file, it doesn’t matter.
  • scratch through the video with the long horizontal slider
  • play the video by clicking on the “play” toggle
  • change the speed of the video with the horizontal speed radio buttons
  • set start and end samples by clicking on the “set” and “end” bangs
  • jump to the start sample by clicking on the “jp” bang
  • loop between the start and end samples by clicking on the “loop” toggle
  • save your start/end sample loop by creating a message box, attaching to [r loopParams] and clicking the “write Params” bang.
  • attach your new message box to the [s targetSamples] object and click on your message to activate the loop area
  • assign the loop area to a key by attaching to the [select box]
Or just watch the video, play with it, and figure it out yourself:
