A number of advanced computer applications and MIDI devices were used in the creation of the compositions. Pieces were primarily created using three tools: MAX/MSP software, the Pro Tools digital audio workstation, and the MPC-2000.
MAX software, by Cycling '74, is an object-oriented graphic programming environment that lets the musician develop processors that create, analyze and manipulate MIDI data. Typically, this data includes notes, timbre changes and various types of controllers that affect such parameters as vibrato depth, sustain pedal and volume. MAX also contains objects that handle scheduling tasks, make decisions, and perform mathematical functions on this data. MSP is a set of additional software objects that extend MAX's capabilities into the realm of digital audio processing, sampling and synthesis.
Digidesign's industry-leading Pro Tools System features a combination of digital audio hardware interfaces and Pro Tools software. This software lets the musician record, edit, process and mix multi-channel audio projects that equal, or exceed, the sound quality of Compact Discs. This system is being run from the Mackie Designs' Baby HUI Human Interface Controller. This portable unit provides the user with physical control of eight audio channels simultaneously, allowing complex movements during a mix that would never be possible using a computer's mouse cursor to control the software.
The MPC-2000 MIDI Production Center, from Akai, has a legendary place in the history of music, particularly in the Electronica and Hip-Hop genres. The function of a 16-pad drum controller is combined with a MIDI sequencer and sampler into a compact, user-friendly device.
Several other MIDI devices have been employed for the concert, notably several Roland XP-10 General MIDI Synthesizers and a Korg KP2 KaoSS Pad.
