A look back at some items in our archives.
I have experienced one of the most interesting
1. open AudioSculpt
2. open your file
3. do a Sonagram Analysis
4. do a Fundamental Frequency Analysis (only if the sound is harmonic)
5. do a Partial Tracking Analysis
6. File: Save Analysis As... -> Save Partial Tracking As...
Notes:
The [http://pyserial.sourceforge.net/|py-serial] module is required. This is not provided with the OS/X default python install. After download, to build an install, run "sudo python ./setup.py install" from the Terminal, within the source code directory.
# Catserial
These pages offer an overview of filters and their use in electroacoustic music.
There are many ways to debug code:
- In circuit debugger: Use the ICSD/ICSP port, a debugger, and the appropriate host software. Lets you step through, watch memory, set breakpoints. This probably does not work well when the USB module is enabled, since its operations are time-sensitive.
# Startup
On platforms with an on-board status LED, the LED will be lit or blinking when the device first initializes. The light will turn off when the user opens the device and begins communication. From this point onward the status lights are under user control.
# Pin Configuration

The foot/switch interface is provided by a soft but “grippy”
toroidal ring of molded rubber embedded in a hard PVC disk.
These disks are sold as “floor protectors” for furniture. A flat
ring of polyurethane foam with a peel-off adhesive is on the
opposite face of the disk. This foam provides the restoring force

This pressure sensor use a printed circuit board (PCB)
containing dozens of adjacent conducting strips and a patch of
piezoresistive fabric made by EEonyx (http://eeonyx.com). The
measuring principle is basically that of the FSR except we have
exchanged the position of the conducting elements and
piezoresistor with respect to the foot.
[inline-left:agile2.jpg]This sensor uses a conductor on either side of the
fabric instead of an interdigitated pair of conductors at the base. The base conductor is a series of overlapped adhesive
copper strips. They form a single conductor because the adhesive itself is a conductive acrylic.
The top conductor is a copper coated nylon fabric. The
[inline-left:Figure4.jpg]The previous designs are limited by the sizes of floor protecting
disks available. This construction is free
of these size constraints.
A half-round wooden strip is cut to the desired length and two
separate strips of copper tape are employed on the flat length
and the curve. A strip of piezoresistive fabric is trapped and
The previous examples use the same physical sensing
principle: gesture modulating current flow. Capacitive or e-field
proximity sensing is an interesting alternative principle to apply
for rapid prototyping. Only one conductor is needed and more
flexibility about where the conductor is placed is available. It
can be under glass, plastic or wood or other non-conducting
material.
To create multiple foot switches we can simply tile out arrays
of the previously described devices. There is a better, faster
way with the additional convenience that the switch functions
are built into a single strip that is constructed quickly in a few
steps. Instead of employing the principal of piezoresistivity
change we employ a printed-resistor position-sensing strip such
This book is an overview of materials, designs and techniques for constructing Foot, Shoe and Sock Controllers with Fiber, Fabric and Other Malleable Materials
A simple gestural controller indeed, but the humble footswitch finds
wide use in technology-based musical performance contexts
because the performer’s hands are usually actively engaged
playing an instrument.
The traditional approach is to mount a
heavy-duty mechanical switch into a solid metal box. These
“stomp boxes” are standard tools of the electric guitarist. As a

Introduction to Joy Slippers project
Then example sections (as child pages of this page) of more fabric based approach covering the various Joy Slippers versions.
Here is a small collection basic use information.
Information about specific platforms / targets.
The OSC address schema of micro-OSC is broken down into a number of modules. Not all modules may be present depending on the hardware support and compile-configuration. Some addresses may change in the future--this document will be updated to reflect the current state of the OSC message address schema.
Enables control over on-board status lights.

**/status/0** : Get/set status light state
Some boards have more status lights, which are numbered /0 /1, etc.
Understands "on", "off", 0, 1.
TX: [ /status/0 ]
RX: [ /status/0 ,i 0 ]
TX: [ /status/0 ,s "on" ]

The profiling system is enabled by a compile-time switch.
