eleVAta SYNTHESIS

Introduction

VIRTUAL

16 VOICE POLYPHONIC SYNTHESIZER

Thank you for purchasing the RED Sound eleVAta 16-voice polyphonic synthesizer.

The Analogue Synthesizer, mainstay of Seventies' and Eighties' music, is back, reinvented in a new, more reliable
and flexible form. Physical modelling via powerful DSPs (Digital Signal Processors) allow all the warmth and control
of the synthesizers of yesteryear without the problems of unstable tuning and unrepeatable sounds, and with
modern benefits like realtime control and multitimbral access.

Welcome to eleVAta, a 16-voice polyphonic synthesizer with all the highlights of the analog tradition, Pulse Width
Modulation, Ring Mod, Resonant Filtering and ADSR Enveloping, combined with all the advantages of modern
MIDI instruments like rock-solid tuning, perfect program recall, velocity response and 8 different timbres
simultaneously available via 6 independent outputs.

So whether your aim is to recreate 'classic' timbres like 70's Disco Bassline / Screaming PWM Lead, chart new
sonic territory with realtime joystick manipulation of parameters such as filter frequency/resonance, or even
combine both approaches in the same MIDI sequence, eleVAta is the perfect tool for you.

With its ingenious ‘elevating’ front panel, eleVAta is as much at home on your studio desktop as it is in any
conventional 3U rack space giving total flexibility in one unit like never before.

In the future, eleVAta's capabilities will grow thanks to the ability to plug-in up to 3 extra EPROM-based DSP
algorithms. This will allow you to use eleVAta’s hardware to produce many different sound generating applications
such as a vocoders.

ANALOG

But eleVAta already offers so much with its marriage of proven synthesis techniques and state-of-the-art control.
Now it's time to unlock the potential of analogue-style synthesis with modern control techniques in your music.

Be creative and elevate your music to new levels!

The evolution of synthesis!

AUDITION

The chrome supports on either side of the chassis automatically drop into 3 sets of locators in the runners of the
side panels to lock the control panel in one of three pre-determined positions, as shown below:

POSITION ONE - FLAT

POSITION TWO - 45 DEGREES

19” Rack

POSITION THREE - 65 DEGREES

POSITION FOUR - VERTICAL

(use this position to mount in 19” rack)

LOWERING THE PANEL:

First you need to release the support arms from their locators. Tilt the control panel
forwards then, using one hand at either side, lift the chrome supports with your index fingers simultaneously before
lowering the panel backwards to the next set of locators, or all the way down to the flat ‘parked’ position. During
panel movements like this you will need to keep continuous upwards pressure on the supports to avoid them
dropping down into their locators.

eleVAta 16-Voice Synthesizer has to offer.

GETTING STARTED

After connecting eleVAta to your system as detailed on page 5, press IN the power switch on the rear panel to turn
the power on. As the software initialises (takes approximately 3 seconds) the main display will show a welcome
message indicating the software version fitted to your unit, as shown below:

PROGRAM MODE - Selecting, editing and saving sounds

eleVAta has two basic modes of operation, PROGRAM mode and MULTI mode. Program mode allows you to work
on single sounds with up to 16 note polyphony and you can store these sounds in any of the 128 USER program
memories. There are also 128 factory ROM programs which cannot be overwritten. For further details on MULTI
mode operation please see page 27 later in the manual.

Operation

OSCILLATOR SECTION

Oscillators

OSC 1

This section of eleVAta produces the musical tones which form the basis of subtractive synthesis. There are two
oscillators per ‘voice’ (musical note), each producing audible vibrations to act as a sound source. The timbre of
each oscillator depends on its harmonic content which is determined by the waveform. There are basically two
waveforms available, SAWTOOTH and SQUARE each with its own specific set of harmonics.

Controls for changing the amount of modulation to the waveform, pitch timbre and pulse width of the oscillators are
also included in this section. These timbral and pitch modulations give the oscillator sound more depth and
stimulate musical appeal to the ear. The oscillator source can also be changed in the MENU section with Formant,
Sine wave and Noise selections on offer as well as two inputs for processing external audio signals.

OSC 1 / OSC 2 SELECT buttons

These two buttons are used to select the ‘active’ oscillator [the one that will be edited by the controls in this
section]. When the [OSC1] button indicator is on oscillator 1 will be selected/edited. When the [OSC2] button
indicator is on oscillator 2 will be selected/edited. Selecting each button automatically cancels the other.

WAVEFORM

This control sets the selected oscillator’s waveform. At the minimum setting [WAVE = 0] the waveform will be
shaped like a SAWTOOTH ( ) . This waveform contains every harmonic in decreasing volume and produces a
very rich sound. As the control is moved in a clockwise direction the shape progressively changes, becoming more
and more ‘squared-off’ until, at the maximum setting [WAVE = 127] the shape will be a SQUARE or ‘pulse’
waveform ( ) . As a pure square wave (max and min values equal) the harmonic content will be all the odd­numbered harmonics in decreasing volume which gives the sound a hollow or ‘woody’ timbre. The width of the
pulse can also be altered by the [PULSE WIDTH] knob to make the sound thinner.

WAVEFORM PITCH PULSE WIDTH

MOD

MOD MOD

DETUNE

MENUOSC 2

PITCH

This control sets the basic pitch of each oscillator. At the mid setting [PITCH = 0] the oscillator pitch will be normal.
Example: when a middle C note is played, the oscillator pitch will be true. The pitch can be in semitone steps
by rotating the control clockwise [+12, +24, +36 etc on the display indicating each octave normal]. Similarly,
the pitch can be in semitone steps by rotating the control anti-clockwise [-12, -24, -36 etc on the display
indicating each octave normal]. Interim semitone settings can be used for 3rd, 5th, 7th tuning etc.

PULSE WIDTH

When the [WAVEFORM] control is set to 64 or above (i.e. a pulse waveform), this control will set the width of the
pulse waveform element. At the minimum setting [PULSE = 0] the fundamental will be at its minimum producing an
extremely thin sound. As the knob is moved in a clockwise direction the pulse width gets wider, with progressively
less high harmonics being added giving the sound a fuller timbre. At the maximum setting [PULSE = 127] the
minimum and maximum values of the pulse width will be equal.
