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 performance 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. 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."
