csoundapi~ in Pd

notes

A preliminary test before trying this in Raspberry-Pi, I used the general instructions for csound in pd from Victor Lazzarini found here:

http://booki.flossmanuals.net/csound/_draft/_v/1.0/csound-in-pd/

to get csound running in pd-extended in Mac OS.

Looks pretty straightforward – biggest question will be compiling the external if it doesn’t install via package manager.

local test files are in tkzic/rpi/pd/csound

Here’s something from Victor Lazzarini which shows csound running on R-Pi

Here is installation instructions from Richard Dobson

Running http: requests from Max

notes
  1. How to separate the status return code  from the actual response data?

For jit.uldl-  status reports get sent out the right outlet and errors are reported in the Max window. However their doesn’t appear to be a way to get the http: status codes or other header data.

For curl, you can write the response (JSON for example) to a file. Then you can read the file using the [js] object and parse the JSON. If you are using [aka.shell] to run the curl command, the stdout and stderr can be routed from the object – for instance, into the Max window. The -v flag (verbose mode) causes curl to output a bunch of header data.

Car engine enhancement with Max and OBD-II

Much of our driving experience is wrapped up in sounds that happen when you press the pedal to the metal. Like Superman emerging from a phone booth, this 2006 Jetta seems different.  The project connects RPM data from an OBD2 diagnostic sensor with the input of the car radio. Via synthesizers.

[update 11/2013 – source code is available at https://github.com/tkzic/automax  – this version features

  • V8 engine
  • Jet engine
  • Spaceship
  • Star Trek TOS transporter button
  • Korg nano-control Midi controller interface]

This project uses the RPM data from an automobile OBD-II port to control the engine speed of an engine simulation from Andy Farnell’s book “Designing Sound”

Here’s the patch that polls and translates OBD-II data

patch is tkzic/automax/rpm4.maxpat

Here’s a Max version of the Farnell car engine simulation:

patch is tkzic/automax/waveguide_engine2e-1.maxpat

Using a Wiimote with Osculator in Max

Update 6/2014: The Max patch is available from the max-projects archive: https://reactivemusic.net/?p=11130

original post

I had a difficult day with wiimotes…

Here’s a general purpose Max patch to read Wiimote Osc data from Osculator:

Some tips…

  • Use a real Wii remote, not the Nyko. If you do get the Nyko, get the one with motion-plus.
  • update Osculator to the latest version
  • Under parameters (in osculator) press + to add the little pacman symbol labeled “same address”, and set the the OSC URL to whatever you’ll be using like 9000 for Max
  • remember to add the Event type (OSC routing) and value (pacman thing) for every wiimote event you’ll be using
  • remember to enter checkbox on the wiimote window for every type of data you want to send
