Special

There are five special functions that make it possible to use MIDI for functions that have previously been reserved for users of analog modular synthesizer systems.

Accessing the Functions

1.Hold down Shift and press Special.

2.Press the Special button as many times is need to make the left digit in the display show the desired function (“1”, “2”, “F”, “A”, “S”, “t” and “E”).

3.Select the Program Slot (A to D) that you want to make settings for.

4.Use the Program Up/Down buttons to set values (the right digit).

The Special Functions can be set up differently for each slot and each slot can use all and any of the Special functions at the same time, if desired.

Function “1” – Synchronizing LFO 1 To MIDI Clock

For this to work you need to feed MIDI clock from a sequencer or similar into the MIDI In of the Nord Lead 2 and activate Play in the sequencer so that MIDI Clock is actually transmitted.

The function synchronizes LFO1’s start to the incoming MIDI Clock so that the LFO starts over at certain intervals. Which interval to use is set with the parameter value:

Value Description

1Restart every other bar

2Restart every whole note

3Restart every half note

4Restart every quarter note

5Restart every eighth note

6Restart every eighth note triplet

7Restart every sixteenth note

Please note that this only makes the LFO restart at the specified note value. In between those restarts, the LFO runs at the rate set with the Rate knob.

Therefore, to “hard sync” the LFO to the tempo of the song when triangle or sawtooth waves are used, set the LFO rate as close to the tempo in the sequencer as possible. On the other hand, unusual Rate values can lead to interesting rhythmic effects.

When random is selected (or when the Arpeggio is used, see below), to “hard sync”, you only need to make sure the set rate is lower than the rate imposed via MIDI.

An Example of LFO 1 Synchronization

1.Select a Program for slot A, that plays a “stable” sound with infinite sustain, for example a “string” or “pad” sound.

2.Lower the Filter Envelope Amount to 0.

3.Set the Filter Cutoff to “nine o’clock”.

4.In the LFO section, select a sawtooth wave, set destination to Filter and set the Amount to full value.

5.Play the keyboard.

You should hear a repeating sound.

6.Hold down Shift and press Special.

The display should show the setting for Special function 1.

7.Press the Program Slot button A.

8.Use the Up/Down buttons to set the value to “5” (eighth notes).

9.Make sure all other Special functions are turned off for this slot.

Do this by pressing the Special button repeatedly and check that the left digit in the display is set to “of” for all Functions except “1”.

10.Press Shift again to return to “normal mode”.

11.Set up your sequencer (or other MIDI device) to transmit MIDI clock to the Nord Lead 2. Set the tempo to around 120 BPM and activate Play in the device so that MIDI clocks are actually transmitted.

12.Play the Nord Lead 2 keyboard and adjust the Rate knob in the LFO 1 section.

Start at approximately 12 o’clock and adjust until you get eighth notes that are in sync with the sequencer. If you raise the Rate slightly from this position you’ll get a shuffle 16th note repeat, etc.

Function “2” – Synchronizing LFO2/Arpeggio to MIDI Clock

This works exactly as Special Function 1, only that it operates on LFO 2 and the Arpeggio instead.

Please note that the explanation about the relation between the LFO rate and the restart via MIDI Clock also applies to the Arpeggio.

This function will not be enabled when Echo is selected on LFO2.

Function “F” – External triggering of Filter Envelope

This function can be used to trigger the Filter envelope via notes coming in via MIDI, instead of by playing the keyboard. The Filter envelope is triggered from its own MIDI Channel and note number(s), completely independent of the MIDI Channel used for defining which keys should be played. This can be used to play back preprogrammed rhythms in your MIDI sequencer while inputting the actual pitch(es) by playing the keyboard or via MIDI.

You can use the Program Select buttons to switch between “of” and “on”. The setting “of” means that the function is turned off and. “on” means that it is activated.

To set which MIDI Channel and possibly which MIDI note number to use for triggering, proceed as follows:

1.Activate the function.

In other words, set the display to “F.on”.

2.Press Store.

The display shows the MIDI Channel currently used. Set the value with the Up/Down buttons.

3.Press Store again.

The Display shows which MIDI Note number is currently used. The numbers start at C0 (MIDI note number 24), and sharp notes (#) are indicated by the symbol . “Middle C” is indicated as “C3”.

The value “– – –” means that note number is ignored, that is all notes on the set MIDI Channel will be used for triggering. This value is found below all the “number values”.

Guidelines for Using Filter Envelope Triggering

▼If you have notes transmitted from your sequencer that you want to use only for triggering the envelope, make sure the MIDI Channel you use for this function is not used by any of the Program slots.

▼Please note that if the Velocity function in the Filter section is activated, the velocities of the incoming MIDI notes are routed to Filter Envelope amount. This allows you to adjust the timbre of the sound with the velocity of the incoming MIDI notes.

An Example of Filter Envelope Triggering

1.Select a Program for slot A, that plays a “stable sound with infinite sustain, for example a “string” or “pad” sound.

2.Lower the Filter Cutoff to 0.

3.Raise the Filter Envelope amount and adjust the Filter envelope so that the sound has a short, snappy character.

4.Hold down Shift and press MIDI Ch. Set the MIDI Channel for slot A to 1.

5.Press each of the other Program slot buttons and set them to MIDI Channel 16.

This is just to make sure they do not get used in this example.

6.Hold down Shift and press Special.

7.Press the Special button until the left digit in the display is “F”.

8.Make sure Program Slot A is selected. Otherwise press its button.

9.Use the Up/Down buttons to set the value to “on”.

10.Press Store. Use the Up/Down buttons to select MIDI Channel “2”.

11.Press Store again and adjust to “– – –” (any MIDI note number).

12.Press Store again.

13.Make sure all other Special functions are turned off for this slot.

Do this by pressing the Special button repeatedly and check that the left digit in the display is set to “of” for all Functions except “F”.

14.Press Shift again to return to “normal mode”.

If you play the keyboard now, you will not get any sound, because the Cutoff is all the way down, and the Filter envelope is no longer triggered by the keyboard.

15.Set up your sequencer to play a simple repeating note pattern on MIDI Channel 2.

The pitches of the notes does not matter, only the rhythm.

16.Hold down a few keys on the keyboard and start the sequencer.

The keys you press should be played with the rhythm from the sequencer.

Function “A” – External triggering of Amplifier Envelope

This function can be used to trigger the Amplifier envelope via notes coming in via MIDI, instead of by playing the keyboard. Just as with the previous function, this can be used to play back preprogrammed rhythms in your MIDI sequencer while inputting the actual pitch(es) by playing the keyboard.

You must play keys on the keyboard, or via MIDI (on the Program slot’s “basic” MIDI Channel), to get any sound!

The parameters are the same as for the Filter Envelope function, see above.

If this function is activated and no MIDI notes are triggering the Amplifier envelope, the instrument will be silent!

Function “5” – External Velocity Morph

This function is used to control the Velocity/Morph function via the velocity numbers of incoming MIDI notes.

This differs from the way Velocity/Morph is normally applied. Normally the velocity is applied each time you press a key. With the External Velocity Control function, however, you can press and hold notes and vary their timbre via the velocity of the incoming notes without releasing the keys (that is – without retriggering the envelopes).

You can use the Program Select buttons to switch between “of” and “on”.

The velocity control happens on its own MIDI Channel and note number(s), completely independent of the MIDI Channel used for defining which keys should be played. It can be controlled from all notes on one MIDI Channel or one specific note number on one MIDI Channel (see Function 3 above for how to specify the MIDI note number and the MIDI Channel).

▼When this function is activated, and a Note On message comes in, the parameters’ values are adjusted according to the note’s Velocity value.

▼When a Note Off message comes in, the Velocity/Morph function is reset to the minimum value.

Please note that you must play the keyboard to hear anything. Also note that the Velocity/Morph must be set up beforehand for this function to have any effect on the sound.

An Example of External Velocity Morph

1.Select a Program for slot A.

2.Edit the Program so that you get a morphing effect you like when you move the modulation wheel.

It is not actually necessary to assign the velocity programming to the Modulation wheel, but it is a practical way to try out the effect before you apply it via MIDI.

3.Hold down Shift and press MIDI Ch. Set the MIDI Channel for slot A to 1.

4.Press each of the other Program slot buttons and set them to MIDI Channel 16.

This is just to make sure they do not get used in this example.

5.Hold down Shift and press Special.

6.Press the Special button until the left digit in the display is “S”.

7.Make sure Program Slot A is selected. Otherwise press its button.

8.Use the Up/Down buttons to set the value to “on”.

9.Press Store. Use the Up/Down buttons to select MIDI Channel “2”.

10.Press Store again and adjust to “– – –” (any MIDI note number).

11.Press Store again.

12.Make sure all other Special functions are turned off for this slot.

Do this by pressing the Special button repeatedly and check that the left digit in the display is set to “of” for all Functions except “S”.

13.Press Shift again to return to “normal mode”.

If you play the keyboard now, there will not be any velocity control because you have set the instrument up to only do this via MIDI.

14.Set up your sequencer to play a sequence of notes with drastically different velocity values.

The pitches of the notes does not matter, only the rhythm and velocity.

15.Hold down a few keys on the keyboard and start the sequencer.

The sound should now vary in character with the velocity values coming out from the sequencer.

Aftertouch and Expression Pedal Settings

The Special menu also contains settings for Aftertouch (“t”) and Expression pedal (“E”) parameter assignment. These functions are described in their respective contents on page 18 (Expression pedal) and page 69 (Aftertouch).
