LFO 2/Arpeggiator

Arp switch

This switch is used to select functionality for LFO 2. When the indicator over the button is lit or blinks, LFO 2 works as an arpeggiator (or an echo; see below). When the indicator is dark, it works as a regular LFO. On the following pages, these two modes are referred to as “Arpeggiator mode” and “LFO mode”.

When you leave Arpeggiator mode by pressing the Arp button, the Arpeggio will be turned off, but the

LFO 2 function will not be activated until you press the right (LFO 2 Destination) button once. This lets you adjust the Rate and Amt knobs before applying vibrato, wah-wah or tremolo.

LFO 2:Arpeggiator Mode

In this mode, LFO 2 works as an arpeggiator. If you take a chord and hold the keys pressed, the notes in the chord will be played back repeatedly, one after the other. The parameters govern direction, range and speed of the arpeggio:

Rate

This adjusts the speed of the arpeggio.

▼When “Echo” is selected (see below), the Rate setting determines the “speed”, i.e. the delay-time between each echo. A higher Rate setting gives a faster echo (shorter delay-time).

The arpeggio speed can also be controlled externally, via MIDI, see page 63.

Arpeggio Mode

By pressing the button to the right in the LFO2/Arpeggiator version, you can select in which direction the arpeggio should run:

Arp Up: In this mode, the keys pressed on the keyboard will be played one after the other, from bottom to top, at a speed set with the Rate button. For more details, see Arp Range below.

Arp Down: As Arp Up but downwards.

Arp Up/Down: To get an up/down arpeggio, press the button until both Arp Up and Arp Down are lit.

Rnd Arp: In this mode (the two upper LEDs lit), Nord Lead 2 will create random arpeggios from the chords you play on the keyboard. This means that the notes in the chord are played back one at a time, but in random order and in random octaves.

Echo: In this mode (The top LED lit), LFO2 creates an echo-effect by using repeated triggering with decreasing velocity (see explanation on the next page).

Arp range

This knob is used to set the octave range of the arpeggio, as the panel indicates. The Off position turns off the arpeggio completely.

▼When Echo is selected, this knob determines the number of echo repeats (0 – 8).

You can select if you want the generated arpeggio notes to also be sent to MIDI Out. See page 61.

Arpeggio Hold

Normally, the arpeggio will continue for as long as you keep any keys pressed. By activating the Arpeggio Hold function, you can release the keys and have the arpeggio continue playing.

▼Activate Arpeggio Hold by holding down Shift and pressing the Arp Switch. The indicator over the button blinks to indicate that Arpeggio Hold is activated.

The arpeggio will continue playing until you hold down Shift and press the Arp Switch again.

If the Arpeggiator is activated, but the Arp range knob is set to “Off”, the Arpeggio Hold switch will work as a regular Hold switch: If you play a note and release the key, the note will continue to sound, as if you were still pressing the key.

About the Echo function

It is important to understand that the Echo function is not the same as a regular audio delay! What happens when you play a note with Echo activated, is that the same note is triggered (played) again the set number of times, with gradually decreasing velocity. This has the following consequences:

▼If the sound you are playing is not sensitive to velocity (Filter Envelope Amount Velocity and Velocity/ Morph are both turned off) there will be no difference whatsoever between the echo repeats.

▼On the other hand, it is fully possible to use the Velocity/Morph function to make the sound change completely with the echo repeats, making the function ideal for special effects.

▼The echo consumes polyphony, i.e. each echo repeat “steals” one voice, just as if you had played the repeats from the keyboard yourself.

This should not be a problem when using the echo effect with short sounds, but if you play long, sustained notes with echo, you could experience notes being cut off by the echo repeats. The solution is to lower the Amt setting (decrease the number of repeats) and possibly play shorter notes.

▼The echo function may give unexpected results if you use another Play mode than Poly.

For example, in Mono mode, each sustaining note will be cut off by the next echo repeat and in Legato mode, you may end up with no sound at all, since new notes will not re-trigger!

FM

When this is selected (the two lower LEDs lit), the wheel controls the amount of FM (see page 39).

Filter

This routes the modulation wheel directly to the filter frequency.

Please note that modulation wheel routing is in addition to the basic setting of the control it is routed to. If you for example route the modulation wheel to the filter, and the filter is already fully open, moving the modulation wheel has no effect.

Poly Legato Mono

The “play mode” switch and LEDs.

The “play mode” switch is used for deciding exactly how your keyboard playing should be interpreted by the synthesizer:

Poly: This mode allows you to play chords.

Legato: This makes the instrument monophonic. Furthermore, if you press a key without releasing the previous, the pitch will change, but the envelopes will not start over. That is, there will be no new “attack”.

Mono: This also makes the instrument monophonic. But if you press a key without releasing the previous, the envelopes are still retriggered, like when you release all keys and then press a new one. Furthermore if you press a key, hold it, press a new key and then release that, the first note is also “retriggered”.

Unison

When this is activated more than one voice will be played when you press a key. This gives you a “fatter” sound, but at the same time reduces polyphony.

▼If Poly mode is selected, two voices are used for each key. This allows you to play eight notes at the same time (provided you are not using Layers).

▼If Mono or Legato mode are selected, four voices are used for each key, for an even fatter sound.

Portamento

The Portamento controls.

Portamento (Time)

This is used to set how long it takes for the pitch to slide from one pitch to the next. If you don’t want any Portamento at all, set this knob to zero.

Auto

When this is activated (LED is lit), the pitch only slides if you play legato, that is if you play a new key before lifting the previous.

The effect of this switch is pretty obvious when you have selected Mono or Legato “Play mode”. If, on the other hand, Poly is selected, the Portamento effect will be slightly unpredictable if Auto is on. For Poly mode, we therefore recommend you to turn Auto off.

Oct Shift

The Octave Shift buttons have two functions, Slot and Keyboard Octave Shift (explained below). To switch between the two Octave Shift modes, simultaneously press both Octave Shift buttons and hold them pressed until the LEDs change indication mode, as shown in this figure:

Slot Octave Shift

This mode will automatically be selected each time you turn on the Nord Lead 2. In this mode, the Octave Shift buttons affect the Program in the selected slot only. Notes sent to MIDI Out are not transposed. This means that in this mode, the Nord Lead 2 can only send MIDI Notes over a range of 4 octaves.

Keyboard Octave Shift

In this mode (LEDs inverted), the actual keyboard is affected by the Octave Shift buttons. This means that all active slots are affected, as well as all notes sent to MIDI Out. This mode is suitable if you want to control other MIDI instruments from the Nord Lead 2, since it lets you control a note range of eight octaves. It is also the mode to use if you’re playing a Performance consisting of two or more slots, and want to be able to Shift all slots simultaneously.

Low/high octave settings in combination with extreme Tune settings for Oscillator 2 may produce pitches outside the hearing range.
