EKSSPERIMENTAL SOUNDS STUDIO ESO1 Manuel utilisateur

USER GUIDE

Thank you for choosing Ekssperimental Sounds ES01 Analog Synthesizer.

The ES01 incorporates advanced synthesizer technology and features

developed for the Reason rack environment with the added convenience

and versatility of a powerful Touch Data Programmer for advanced

internal routing and customization.

We urge you to read this user guide thoroughly in order to make the most

of your ES01 Analog Synthesizer.

INTRODUCTION

Power/Volume

This control serves the multi function of power switch, volume control

and note indicator.

If rotated clockwise the unit is turned ON and the indicator LED is lit.

Volume increases as the control is rotated towards the “10” at the end

of its scale. The LED will ash when ES01 receives notes via CV Gate or

MIDI.

GLOBAL SETTINGS

The ES01 is a by default a monophonic synthesizer but can be

congured to play up to 16 voices simultaneously in the Polyphonic

Mode, with Unison activated the total voices is reduced to 8.

Find all settings for polyphony, lters and oscillators under the tab

“GLOBAL SETTINGS” in the Touch Data Programmer.

Further information about the global settings on page 9.

BASIC SETTINGS

Feet Selector

This selector determines the ground

range of the ES01 pitch. If this

selector is set to “WN” white noise

is produced. By applying ltration to

this noise with the VCF the sound of

wind, waves and other cool effects

can be created.

Sub Oscillator

ES01 has one Sub Oscillator that

can be set to -1 or -2 octaves.

It follows the regular oscillator.

Activate and adjust the level and

waveform of the Sub Oscillator in

the GLOBAL SETTINGS tab in the

Touch Data Programmer.

Pitch Lever

This is the ES01 tuning control It

permits a tuning of -/+50 cents so

that you can match the pitch of

ES01 with that of other instruments.

Waveform Selector

Determines the waveform produced by the VCO. The different waveforms

have different types and numbers of harmonics and therefor different

sounds.

The ES01 offers four waveforms and a pulse width modulation feature as

shown in this chart:

Triangular wave Subdued, ideal for ute sounds.

Sawtooth wave Bright, perfect for string and brass sounds.

Square wave Woody tone, good for clarinet sound.

Rectangular wave Vibrant, great for trumpet, oboe etc.

PWM Thick, rich sound. Awesome for acid techno and synthetic sounds.

The Voltage Controlled Oscillator is the basic sound generator of the ES01.

The pitch of its signal is determined by the input of CV and MIDI message from your keyboard or sequencer.

Try switching the FEET and/or the wave selector while

playing or modulating it with the LFO, CV input or other

sources via the MOD panel in the Touch Data Programmer.

VCO

Glissando

Creates a glissando between notes played. The transition between notes

can be set to either “Stepped” or “Smooth” via GLOBAL SETTINGS in

the Touch Data programmer.

Freq Cut Off

Setting the VCF to the “H” end

allows upper harmonics to pass,

thereby creating a bright tonality.

Moving the control towards the

“L” end of the scale gradually cuts

off more and more harmonics,

creating a softer tonality. You

can increase the range of this

control via GLOBAL SETTINGS in

the Touch Data Programmer by

switching Filter Mode from Original

Range to Extended. You can also

change the slope of this lter from

the default 12 dB/octave to a more

drastic 24 dB/octave.

EG Depth

Determines to what degree the

envelope settings of the EG

section affects the VCF cut off

frequency. This permits creation of

a broad range of interesting time-

based tonal variation effects.

VCA EG Depth

This lever determines to what

degree the envelope settings of

the EG section affects the level of

the sound (dB).

When using a Breath Controller

signal (BC IN) you might want to

lower this lever to let the BC IN

signal decide the amount of sound

amplication.

You can also modulate the VCA

Level via the Mod Matrix in the

Touch Data Programmer.

The Voltage Controlled Filter alters the sound by cutting off frequencies.

Resonance selector

Set to the “H” position frequencies

near the lter cut off frequency are

emphasized for a “sharper” sound.

By setting the Filter Mode in

GLOBAL SETTINGS to ”Extended

Range” you will also increase the

resonance range.

FREQUENCY

12dB/oct

Attack Time

This controls the time for the

sound to reach maximum level

when a note is played.

Decay Time

Controls how long it take for the

sound the decrease to sustain

after the maximum level has been

reached. If the sustain control is

set to maximum no decay effect

will be noticeable.

Sustain Level

Determines the continuous level to

be maintain after attack and decay

have nished, as long as a note is

played.

Release Time

The time it take for the sound to

completely fade out after the note

has been released.

ENVELOPE GENERATOR

The EG block contains the ES01 envelope generator controls.

PWM (Pulse width modulation)

This function varies the width of

the pulse in each cycle determined

by the speed set by the PWM

SPEED control. This function can

be used to create a variety of cho-

rus-like effects and add organic

feel to your tones.

CV (Control Voltage)

The CV jacks on the backside can

be used for modulation and is

accessible via the MOD matrix.

BC CV IN

The ES01 can be modulated via

Breath Control or the BC CV jacks

prerouted to the control knobs on

the front panel.

MODULATION

There are many ways to modulate the sound within the ES01, either by LFO, PWM, Mod Matrix or CV input.

LFO (Low frequency oscillator)

The LFO is prerouted to the Mod

Wheel which has a three way

switch allowing you to send the

modulation to VCO, VCF or VCA to

create periodic variations in pitch,

tone or volume. This routing can

be deactivated via the GLOBAL

SETTINGS tab in the Touch Data

Programmer. The LFO can also be

accessed in the MOD matrix.

LFO WAVE

Select the character of the

modulation from these ve

waveforms:

Sine Triangle Saw

Pulse Random

LFO SPEED

Determines the frequency of the

LFO from S (slow) to F (fast).

PITCH BEND

Pitch can be bent by 1 octave up

or down.

MODULATION MATRIX

MOD 1 & MOD 2

The modulation matrix provides

a total of 16 slots divided on two

pages, MOD1 & MOD2.

As an example try selecting “LFO

Unipolar” as the source, dial in -79

as the amount and select FEET as

the destination.

Set the LFO wave selector to

Sawtooth and the Feet selector to

4’ and hear a 4 octave arpeggio

controlled by the speed of the LFO.

You can sync the LFO to the

tempo of the song by changing it

from “Original Speed” to “Tempo

Synced” under the GLOBAL

SETTINGS tab in the TOUCH DATA

PROGRAMMER.

Feet changes at these + and –

values: 20, 40, 60, 80, 100

The BC Knobs are prerouted

for quick modulation via the

front panel. The prerouting can

be switched off under GLOBAL

SETTINGS, making the knobs

suitable as SOURCE and SCALE

controls within the modulation

matrix.

The vast possibilities of the

modulation matrix makes the ES01

much more versatile then the rst

impression might imply.

All Destination and Scale amounts

can be controlled via Combinators

and automation.

VOICES

ES01 can be set to Mono Retrig

(Default), Mono Legato and

Polyphonic (16 voices) mode.

Unison ON multiplies the voice by

4 and spreads the new voices in

the stereo eld with a slight detune

of each voice, creating a fatter and

more vibrant sound. In polyphonic

mode the voices are reduced from

16 to 8 when Unison is ON.

SUB OSC

The sub oscillator can be set to

OFF, -1 Octave and -2 Octaves.

Triangle, Square, Saw and Noise

can be selected as the waveform.

When Noise is selected the -1

Octave option produces white

noise while the -2 Octaves

produces pink noise.

VCF

Original Range limits the lter to

a ne tuned range. The Extended

range opens this limit and allows

for much more extreme ltering.

LFO

The Low Frequency Oscillator can

be set to Original Speed, Extended

Speed and to Tempo Sync.

Retrig ON causes the LFO to restart

on each new note.

PWM

The Pulse Width Modulation speed

can be set to Original Speed,

Extended Speed and to Tempo

Sync.

Retrig ON causes the PWM cycle

to restart on each new note.

MOD WHEEL

The range of the Mod Wheel can be

set to Original or Extended Depth.

Prerouting can be switched ON or

OFF.

GLISSANDO

Can be set to ON or AUTO. With

the AUTO option the Glissando

is activated only when notes are

played Legato.

Glissando can be set to either

Stepped or Smooth.

With Hold Notes set to ON the

last played note is held, making it

possible to produce sound with a

Breath Controller even when the

key has been released.

Prerouting ON / OFF activates and

deactivates the BC VCF and VCA

controll knobs.

Mod Functions

Sources & Destinations

Most of the options have a clear

link to the controls on the panel

or an obvious function. Here are

a brief explanation of the more

special ones:

Glissando

Similar to Note Number but also

looks at the current note value of

the glissando.

Held Notes

In poly mode when holding more

then one note each held note

increases the value.

Latched CV

The CV value at Note on-event

Random

Each new Note On event gives a

random value

LFO

Bipolar (default) generating both

negative and positive values based

on the LFO waveform. (Fig.1a)

Unipolar shifts the base of the

waveform to only modulate positive

or negative values (Fig.1b)

Shifted 90 degrees is a bipolar

modulation where the waveform is

shifted 90 degrees meaning it will

be one 4th cycle shifted in time.

(Fig.2)

The three options above are

dependent on the position of the

WAVE selector but all individual

LFO waveforms can be accessed

in the modulation menu. The

individual waveforms are always

bipolar.
