Lightning II Description
LIGHTNING II is a specialized MIDI controller that senses the position and movement of handheld wands and transforms this information to MIDI signals for expressive control of electronic musical instrumentation. In addition to functioning as a powerful MIDI controller, LIGHTNING II, with its self contained 32 voice synthesizer, comprises a complete, ready to play instrument.

[IMAGE] Based on principles of optical triangulation, LIGHTNING gathers its information by tracking tiny infrared transmitters that are built into baton-like wands. Unencumbered by wires, these wands provide complete freedom of movement within a performance space that can be as large as 12 feet high by 20 feet wide.
Basically, LIGHTNING II senses the horizontal and vertical position of each hand, for a total of four independent coordinates. From this information, LIGHTNING's digital signal processor computes instantaneous velocity and acceleration, and performs detailed analysis of gesture. An easily mastered, musically oriented interface language allows the user to define relationships between various gestures and potential musical responses.
In one sort of implementation, LIGHTNING's coordinates might be mapped to various MIDI controllers on multiple channels. Spatial pitch wheels, pan pots, level sliders and modulation wheels are easily defined and great fun to play. Performance gestures can be analyzed for direction and velocity and can be used to generate a variety of notes as well as other musical events. Multi-dimensional zoning capability can be used to create different musical responses in different regions. Everything you need to create the conceptual ensemble (an invisible, acoustic virtual reality).
User definable scale and tuning tables allow one to determine the range and selection of notes occurring along a horizontal or vertical axis. Pitches can be in any order, and the boundaries can be set where ever desired, facilitating the creation of spatial instruments and imaginary orchestras.
LIGHTNING II features a conducting facility that can analyze a conductor's gestures, display deviations from a preset tempo, and signal errors such as missed beats. Simultaneously, LIGHTNING can transmit a synchronous MIDI clock for controlling external sequencers and output programmed note data to accompany specific beats within a measure.

An additional thirty presets can be stored in RAM, and yet another thirty ROM based presets are provided as tutorial examples (good places to begin the LIGHTNING experience).
To facilitate its use in conjunction with other controllers, LIGHTNING possesses intelligent MIDI merging capability. A complete system exclusive implementation enables LIGHTNING presets to be stored and edited via external computers and sequencers.

Lightning II Frequently Asked Questions
What are the differences between the original Lightning and Lightning II?
Quite a few features were added to Lightning II. Some of the more significant are: * The original Lightning housed the electronics and optics in the same box, requiring that the box be mounted on a stand. Lightning II remotes the optics, and houses the electronics in a separate half rack cabinet. This results in simpler editing, an unobtrusive optical pickup (the remote head), and easily viewed displays of zones and preset numbers (now contained in the remote). * Lightning II exhibits substantially increased operating range, through improvements in electronics, optics, and wand design. * Lightning II wands utilize replaceable batteries, and transmit for many more hours before requiring battery replacement (15 hours versus 2). The new wands are dual range - for patch design or relatively close playing, use the low range and your battery will go for around 60 hours. A blinking L.E.D provides ample advance warning that the battery is about to expire. * The number of internal, RAM based presets has been increased from 12 to 30. Fixed presets are increased from 3 to 30. * Lightning II accommodates a memory card, which can store an additional 30 presets per card. These cards make great backups, provide immediate access to an unlimited number of presets, and simplify the transmission of presets between users. * Lightning II contains a synthesizer, facilitating demos and augmenting the performance possibilities. We still regard Lightning as basically a controller, but that built-in synth does come in handy. * Numerous software improvements (too many to list) are incorporated into Lightning II.
Can Lightning I be upgraded to Lightning II? * Unfortunately not. The expense of implementing the required changes would approach the cost of a new Lightning II. The one exception is the improved Lightning II wands; these can be substituted for the original wands.
Where can I see a Lightning II? * That's a hard one. Musical instrument stores are reluctant to deal with alternative controllers (or alternatives to anything, for that matter), so a trip to your local guitar center probably won't pan out. * A few learn of Lightning from friends and associates that already have one, but for most, that's not too likely. * Others first see Lightning used on stage - musicians and dancers are often happy to show people the instrument - try checking out the stage after the show. * While not the same as a personal encounter, reviewers do try to provide reasonably accurate and unbiased assessments, and product reviews may provide useful third party input. The original Lightning was reviewed in the September, 1991 issue of Keyboard, and the October, 1991 issue of Electronic Musician; Lightning II reviews will likely show up in mid 1996.
What kind of Synth is built into Lightning II?
Lightning II's synthesizer utilizes the Kurzweil chip set, which has the following characteristics: * Uses the Kurzweil Multimedia Audio Sample-playback System (MASS) technology. * 16 MIDI channels with dynamic voice allocation and 32 voice polyphony. * A 6 megabyte wavetable memory contains 357 sound programs (but with some redundancy), including General MIDI, Roland MT-32, Roland LAPC-1, and Kurzweil Super-Orchestral patches. Additionally, there are a bunch of drum kits, containing a few hundred additional sounds. (Lightning II supports bank selection, even for individual channels.) * Digital sound effects processor provides global delays and reverb. * The audio converter is the 64x oversampled sigma-delta, 18 bit variety. Bandwidth is 20 kHz; the dynamic range is way up there; and it sounds clean (like the Kurzweil 2000).
