The source of thisĮrratic temporal performance seems to be context switches between the X Is that the elapsed times greater than 1 ms averaged about 28 ms and wereĭistributed more or less in a bell curve around 28 ms. Parameter updates came within 1 ms of the previous update. Of position, tilt, and pressure while continually moving the stylus so as We performed timing experiments on SGI machines using theirįast UST clock, measuring the elapsed time between events reporting values It is important to evaluate the temporal behavior of computer systemsįor music. Tip side or eraser side) enters or leaves proximity. For the stylus, this event indicates which side (stylus Kind of event is generated when either device enters or leaves the proximity Stylus into the tablet will cause the same kind of button event. Each tip of the stylus can be considered a button pressing the The puck has 4 buttons, and the stylus has two buttonsĪs well. In addition to these continuous control variables, there are many ways Tablet, within about a centimeter of the surface. Reported whenever the stylus or puck is in "proximity" of the In two dimensions, in the range -60 to 60 degrees. When only the stylus is used, the Wacom tablet also outputs tilt values Tip on the other end) that produces pressure readings in the range 0 toĢ55. Has a pressure-sensitive tip (and a pressure-sensitive "eraser" The Wacom tablet accurately outputs the absolute X and Y dimensions ofīoth the puck and stylus as integers in the range 0 to 32480. We've had no trouble running the cable at distances of about 30 feet.
#The synthesizer has virtually no standard repertoire. serial#
Power and control information on the other side of the cable is a mini-dinĬonnector suitable for the serial port on a Macintosh, PC, or SGI workstation. The tablet has a single DB-9 connector that carries both The stylus and puck are cordless, batteryless, and Model with both a stylus (pen) and a puck (mouse-like device) that allows We use a Wacom ArtZ II 1212 digitizing tablet, a 12 inch by 12 inch These controllers can be used for musical control in a variety of interestingĪnd musically expressive ways. Such as pen or pointing device position, pressure, and tilt. These tabletsĪre broadly available and low cost, and they sense many control dimensions "artist's tablet") primarily for the purpose ofĭrawing shapes in computer graphics illustration programs. The computer industry has developed the digitizing Throughout history, people have adapted objects in their environment We define a powerful, high-level model for mapping tablet data to musical control information and conclude with a list of example applications. We characteristize the device in terms of the data it outputs, the resolution of that data, and temporal behavior. We have adapted a digitizing tablet as a musical gestural controller.
