Introduction

Product Description

Upgradable Sounds

Halo contains a new collection of presets designed for music composition
in a wide variety of styles.These sounds are rich in harmonic texture and a
perfect complement to the Z-plane filters. Halo contains three additional,
user-upgradable sound SIMM sockets, allowing you to mix and match
sound sets according to your needs. New sounds can be added as easily as
plugging in a new 16MB or 32MB SIMM module. Each sound set has been
meticulously crafted to be the finest of its kind. Samples are expertly
matched across the keyboard and perfectly looped to create realistic instru­ments which form the exceptionally playable presets.

1024 Presets & more

Halo contains 512 user presets and 512 factory ROM presets, but it can be
expanded with literally thousands of ROM presets. (ROM presets are

automatically added when sound SIMMs are installed. As an example, a 32 MB
SIMM may contain up to 1024 ROM presets.) Halo’s Sound Navigator makes it

easy to find the exact sound you want. It’s powerful, yet simple to use.

Velocity & Pressure Sensitive Keyboard

The five-octave, velocity sensitive keyboard with aftertouch allows you to
perform live or record via MIDI into an external computer/sequencer. The
keyboard action is extremely responsive, capturing all the subtle nuances of
your performance.

Multi-Function Controllers

Multi-function buttons allow you to trigger arpeggiators and notes inter­nally or on any of your other MIDI devices. They can act as preset select
buttons or Beats Mute or MIDI Trigger buttons (latched or unlatched).

Four real-time controller knobs are also multi-function controls. These
knobs make it a snap to edit and modify internal preset parameters. The
controllers are fully programmable and can control internal preset or other
MIDI equipment. They can also be programmed to adjust multiple internal
parameters at once, allowing complex levels of control. For example, a
single knob can simultaneously turn up filter cutoff, while detuning one

sample, and adjusting the release time of the volume envelope. Virtually
every synth parameter in the Halo is controllable using the real-time knobs
or by any internal or external control source.

SuperBeats

Beats Mode is a whole new way to create dynamic, original music. With
Beats, you trigger, latch and unlatch synced loops and grooves from the
sixteen trigger keys. Simply select a bts: preset and go. Then use Halo’s
perfomance controls to alter and mutate the rhythm or the sound itself.

Multi-Channel Arpeggiators

Halo’s Rhythmic Pattern Generator/Arpeggiator can play up to 16 synchro­nized arpeggiator patterns at once using a different sound for each! Patterns
can be edited using pattern flow commands such as: delay for 2 bars, play
for 4 bars, hold for 2 beats and repeat. You can program or download 100
user patterns in addition to the 200 factory patterns.

Ultra Powerful Synthesizer

The extremely flexible yet easy to use synthesizer makes it easy to build
sounds of any kind. Up to 4 four layers can be switched or crossfaded using
key position, velocity, real-time controllers or any modulation source. 64
voice polyphony ensures that you can play and sequence the most complex
material. Halo also contains 50 different 2nd to 12th order resonant &
modeling filters which are used to shape and modify over 1200 waveforms
contained in 32 megabytes (MB) of ROM.

Sixty-four modulation sources include three multistage envelopes and two
LFOs per layer, as well as full MIDI control over virtually every parameter.
The digital patch bay, with 24 cords per layer, (and 12 more cords per
preset) lets you connect modulation sources to 64 destinations in any
imaginable way. The patch bay also contains a set of arithmetic modifiers,
allowing you to create complex synthesis models. Synth parameters as well
as arpeggiator and BEAT tempos can be controlled from Halo’s internal
clock (or an external MIDI clock). Up to 8 LFOs and 12 envelopes can be
perfectly synchronized at different rates.

24-bit Effects

Once you have created your preset, you can add richness to your sound
using Halo’s 24-bit stereo effects. You can choose a different effects setup for
each preset from over 60 algorithms. Halo’s effects section is actually two
separate effects processors with control over each wet/dry mix level on four
effects sends. Effects Processor “A” contains primarily ambiance algorithms
like reverb and delays, while effects processor “B” contains primarily
spectral algorithms such as chorus, flange, phase, distortion, and delay.
Effects can be linked to each preset or used globally for increased flexibility.

ENSONIQ

Other features include multiple solo, voice assignment and performance
modes for expressive control, 12 user-definable alternate tunings, and, of
course, an extensive MIDI implementation.

Interférences
Radio et
Télévision

L’appareil décrit dans cette notice génére et utilise une énergie de
fréquence-radio. S’il n’est pas installé et utilisé correctement - c’est à dire en
suivant strictement nos instructions - il peut occasionner des interférences
avec la réception d’une radio ou d’une télévision.

avec les spécifications du paragraphe J de la section 15 des lois FCC. Ces lois
sont désignées pour fournir une protection raisonnable contre de telles
interférences dans une installation résidentielle. Toutefois, il n’est pas
garanti qu’aucune interférence n’apparaisse dans des installations
particulières, et plus spécialement lorsqu’une antenne de télévision en
«oreilles de lapin» est utilisée.

Si le Halo occasionne des interférences , vous pouvez essayer de les corriger
en utilisant une ou plusieurs des mesures suivantes:

• Tournez l’antenne de la télé ou de la radio jusqu’à ce que les inter­férences disparaissent.

• Déplacez le Halo d’un côté ou de l’autre de la télé ou de la radio.

• Eloignez le Halo de la télé ou de la radio.

• Branchez le Halo sur une prise différente que la télé ou la radio.

Power Switch & AC Receptacle

The AC power switch is located on the rear panel. There is no 110/220 Volt
power selector switch since Halo utilizes an auto-switching power supply
which accepts from 100V-250V, 50-60Hz.

MIDI Output

The Halo can control other MIDI instruments by connecting a MIDI cable
between the MIDI out of Halo and the MIDI Input of the other instrument.

Outputs

In order to reproduce Halo’s wide dynamic range and frequency response,
use a high quality amplification and speaker system and a stereo setup is
highly desirable The headphone output is the same as the Main output
signal. The headphone jack is located on the left side of the front panel.

Footswitch & Footpedal

Connect a momentary footswitch and a Control Pedal for additional
control. Halo auto-senses either normally-open or normally-closed switches
See page 15 for information about how the footpedal should be wired.

Audio Outputs

The Sub 1 output jacks are stereo jacks. The tip of each jack (accessed when
a standard phone plug is inserted) connects to the left or right output of
that group.

If you insert a stereo plug into one of the Sub Outputs, the ring of the plug
serves as a signal Return which sums into the Main outputs.

Setup

Studio Setup

Therefore, the Sub 1 jacks can serve as effect sends and returns
in order to further process selected instruments and then
return them to the main mix.

You can use the Sub 1 jacks as send/returns in order to further process
selected Halo presets without using the effects bus on the mixing board. In
a pinch, the effect returns can be used to sum additional instruments into
the main outputs. It’s like having an extra line mixer when you need more
inputs!
