Technology
The Mandala pad represents patented membrane sensor technology that was developed over several years by Vince DeFranco and was released to the public in May 2006.
Because a Mandala surface is divided into 128 position rings and can detect 127 strike velocities (greater than 0) it can produce up to 16,256 (128 x 127) individual triggers. For practical playing the pad can be concentrically divided into as little as one or as many as six playing zones via its Virtual Brain software. The individual zones, position rings, and velocity levels can be used to trigger different instruments, effects parameters, or volume changes.
The newest version of the Mandala, mk2.9, is a standard class-compliant USB MIDI controller (no special drivers required) which uses a computer as its sound source. When the pad is struck it sends a MIDI trigger note with velocity as well as a position value (in the form of a MIDI continuous controller) across a USB cable into a computer. A Virtual Brain program is included with mk2.9 and has a set of included instrument samples and multiple effects (filters, delay, distortion, etc.) which can be applied to individual zones or to the overall surface. Unlimited user samples can also be added to the included sound library. Any parameter of any effect can be controlled by the position (0-127) or velocity (0-127) of a surface strike, resulting in effects such as bending pitch, changing delay time, or increasing reverb as the pad is played from center to edge. The position controller and velocity controller can be scaled to the player's liking. Factory preset sound configurations are included with the Virtual Brain as well as unlimited empty slots for user created presets. Drummers can also modify panning and note settings for each zone. The Virtual Brain program is not required to play the Mandala because the pad is a MIDI controller that can trigger any software that accepts MIDI input.
Mk2.9 demonstrates the resolution of its sensitivity by including a bonus of over 1500 position and velocity based samples of a single vintage snare drum which get laid out over the Mandala surface for an accurate playing representation.
Version 1.0 of the Mandala included a standalone hardware 'brain' with an onboard sound chip and effects. That version is no longer available.

Famous quotes containing the word technology:
“One can prove or refute anything at all with words. Soon people will perfect language technology to such an extent that they’ll be proving with mathematical precision that twice two is seven.”
—Anton Pavlovich Chekhov (1860–1904)
“Primitive peoples tried to annul death by portraying the human body—we do it by finding substitutes for the human body. Technology instead of mysticism!”
—Max Frisch (1911–1991)
“If the technology cannot shoulder the entire burden of strategic change, it nevertheless can set into motion a series of dynamics that present an important challenge to imperative control and the industrial division of labor. The more blurred the distinction between what workers know and what managers know, the more fragile and pointless any traditional relationships of domination and subordination between them will become.”
—Shoshana Zuboff (b. 1951)
