micro-OSC is a sensor/actuation interface firmware for the PIC18F USB-FS series embedded microprocessor that runs on low-cost general purpose prototype boards.  micro-OSC implements the Open Sound Control protocol directly in the hardware, including support for clock synchronization, state-machine-free operation, scheduling and high-speed floating point data streams. The project is supported by CNMAT and driven by needs in research and design of new electronic musical instruments.

Objects for Max/MSP/Jitter

I have written several objects for the Max/MSP/Jitter graphical dataflow environment, they are available here:
  • accumulate~: signal integration and leaky integration with signal control model
  • firbank~: an efficient FIR filterbank implemented with FFT overlap-save
  • OSC-timetag: support for high-resolution NTP timestamps
  • OSC-schedule: millisecond-accuracy scheduling for timestamped OSC bundles


Jack client for Python. This project project is now on

Open Sound Control for PHP

A small PHP class which can format and send OSC messages. It has no parsing capability, so it can only be used for uni-directional communication.

18K 2007 OSC.php


Version 0.2: March 22, 2007. Fixes a bug in timetag encoding for bundles.
Version 0.1: 2004 Initial release.

Open Sound Control for MATLAB

A very fast OSC implementation for Matlab with good type support that maps naturally into the native Matlab type system. Formatting and parsing is done in C using liblo. Precompiled binaries are provided for Windows (so you don't have to suffer what I did) and Mac-Intel (YMMV). The windows binaries are known to work with Matlab 6.5 or later.

A small collection of utilities for server management (typically Debian or a related distro (Ubuntu)).
  • multithreaded "reload" performance benchmark for a webserver
  • keep rotating backups on multiple schedules (for mysql dumps, svn exports, file system snapshots)
  • automatically monitor SSH bruteforce-attacks and temporarily block offenders
  • automate the task of propagating a public key for passwordless SSH authentication
