Decay

When the attack phase is over, and the key is still held down, the enve-

lope drops back to zero level. Use the Decay knob to set the time this

should take. If the Decay time is set to the maximum, the envelope will

remain on a sustained level until the key is released.

Release

When the key is released, the envelope enters the release stage. The

release time is set with the release knob.

Amp Envelope

The ﬁnal stage of a synth signal chain usually consists

of an ampliﬁer to control the volume. By modulating the

ampliﬁer with an envelope, the sound is given its basic

“shape” over time. In fact, the “volume shape” is one of

the most important factors to how we identify the sound.

By setting up a proper volume envelope you can make a

sound “soft”, “hard”, “plucked” “static” etc.

The Amp Envelope has the same three stages as the

Mod Envelope:

Attack

The Attack knob is used to adjust how long it should take for the sound

to reach from zero to full amplitude after a key has been pressed. With

long Attack settings the sound will gradually “fade in”.

Decay

When the attack phase is over, the envelope drops back to zero level.

Use the Decay knob to set the time this should take. If the Decay time

is set to the maximum, the envelope will remain on a sustained level

until the key is released.

Release

When the key is released, the envelope enters the release stage. The

release time is set with the release knob.

The LFO

The LFO is a Low Frequency Oscillator, producing

waveforms with the following characteristics:

•The LFO is capable of producing waveforms with

a very low frequency.

•LFOs are not used for generating audible frequen-

cies. Instead the output from the LFO is used for

modulating, that is controlling, other functions,

like for example the Shape parameter on the Stage 2 oscillator or the

ﬁlter frequency.

The rate of the LFO is set with the Rate knob. The range is from 0.03

to 523 Hz.

The Waveform Selector button determines the waveform that is gener-

ated by the LFO.

Waveform Description

* Note that the Modulation always starts at maximum amplitude level for the AMP destination

Square (no LED lit)

Use for abrupt modulation changes, suit-

able for trills, distinct tremolos, etc.

* Note that the Modulation always starts at maximum amplitude level for the AMP destination

Sawtooth

Use for ramp type modulations.

* Note that the Modulation always starts at maximum amplitude level for the AMP destination

Triangle

Suitable for natural vibrato effects and also

used for classic pulse width modulation.

S/H

Sample & Hold

Creates an smooth random modulation.

MST CLK

Press Shift and the LFO waveform button to sync the rate of the LFO

to the Stage 2’s Master clock.

When the LFO is synchronized to the Master Clock, the Rate knob will

be used to set the arpeggio’s subdivison of the tempo of the Master

Clock. The Subdivisions are described in meter: ½ equals half notes

at the clock tempo, ¼ equals quarter notes, 1/8 are eight notes etc..

Read more about this feature on page 18.

Velocity

Amp Env Velocity

When the Amp Env Velocity LED is lit, the level of

the synth sound will be controlled by the velocity you use when you

play on the keyboard.

Mod Env Velocity

When the Mod Env Velocity LED is lit, you will control the amplitude of

the Modulation Envelope, by the velocity you use when you play on

the keyboard. Play harder and the Mod Env will affect the parameter(s)

more.

Voices section

In this section, you set various voice

modes for the synthesizer. You can

choose between monophonic and poly-

phonic playing, and control glide between

notes. You will also ﬁnd the powerful

Unison mode.

Voice Mode Mono

In Mono mode you can only play one note at a time, just like on a tradi-

tional monophonic synthesizer. If you play one key and then a second

key without releasing the ﬁrst key, the last note will sound. If you now

release the last key, the ﬁrst one will be re-triggered and start sound-

ing again. If you play a new key before releasing the previously played

key (legato), the new note will replace the previous one at the current

Envelope stage of the previously pressed key. The new note will not

re-trigger the envelopes.

M If you use samples and mono, the envelopes will be re-triggered

even if you play legato .

To activate Mono mode, press the selector button until the Mono LED

lights up.
