the arpeggIator

The UltraNova has a powerful Arpeggiator feature which allows arpeggios of varying
complexity and rhythm to be played. If a single key is pressed, the note will be retriggered
by the Arpeggiator. If you play a chord, the Arpeggiator identiies its notes and plays them
individually in sequence (this is termed an arpeggio pattern or “arp sequence”); thus if you
play a C major triad, the selected notes will be C, E and G.

Arpeggiator operation in the UltraNova is controlled by the three

ARP

buttons [20],

SETTINGS

and

LATCH

. The ON button enables or disables the Arpeggiator, while the

LATCH

button plays the currently selected arp sequence repeatedly without the keys being

held.

LATCH

can also be pressed before the Arpeggiator is enabled. When the Arpeggia-

tor is enabled, the UltraNova will immediately play the arp sequence deined by the last set
of notes played, and will do so indeinitely.

Editing of all Arpeggiator functions is carried out in the Arpeggiator Menu, which is opened
by pressing the

SETTINGS

button.

RE1: Arpeggiator Rate Sync

Displayed as:

ArpSync

Initial value:

16th

Range of adjustment:

see table at page 40

This parameter effectively determines the beat of the arp sequence, based on the tempo
rate set by RE8.

RE2: Arpeggiator Mode

Displayed as:

ArpMode

Initial value:

Range of adjustment:

see table at page 44

When enabled, the Arpeggiator will play all notes held down in a sequence which is deter-
mined by the

ArpMode

parameter. The third column of the table describes the nature of

the sequence in each case.

RE3: Arpeggiator Pattern

Displayed as:

ArpPatt

Initial value:

Range of adjustment:

1 to 33

As well as being able to set the basic timing and mode of the arp sequence (with

RE1

and

RE2

), you can also introduce further rhythmic variations with the

Arpeggiator Pattern

parameter.

You should spend some time experimenting with different combinations of Arp
Mode and Arp Pattern. Some patterns work better in certain Modes.

RE4: Arpeggiator Gate Time

Displayed as:

ArpGTime

Initial value:

Range of adjustment:

1 to 127

This parameter sets the basic duration of the notes played by the Arpeggiator (though this
will be further amended by both the

ArpPatt

and

ArpSync

settings). The lower the param-

eter value, the shorter the duration of the note played. At its maximum value, one note in the
sequence is immediately followed by the next without a gap. At the default value of 64, the
note duration is exactly half the beat interval (as set by

RE8

Tempo Clock), and each note

is followed by a rest of equal length.

RE5: Arpeggiator Octaves

Displayed as:

ArpOctve

Initial value:

Range of adjustment:

1 to 8

This setting adds upper octaves to the arp sequence. If ArpOctve is set to 2, the sequence
is played as normal, then immediately played again an octave higher. Higher values of Ar-
pOctve extend this process by adding additional higher octaves. ArpOctve values greater
than 1 have the effect of doubling, tripling, etc., the length of the sequence. The additional
notes added duplicate the complete original sequence, but octave-shifted. Thus a four-note
sequence played with ArpOctve set to 1, will consist of eight notes when ArpOctve is set
to 2.

Tweak Menu Page 2:

Each encoder may have any of the available parameters (see list at page 42) assigned to it
for adjustment. Any Tweak Control assignments which form part of a fcatory Patch will be
displayed.

Tweak Menu Page 1:

When a parameter is been assigned to a rotary encoder – either as part of the Patch or
via manual assignment - the upper row shows the parameter name and the lower row the
parameter value, just as they are displayed in their “native” menu.

Note that Tweak and Touch modes are mutually exclusive – the encoders cannot be
assigned to both functions simultaneously, either globally or individually.

Touched/Filter Knob

The large

TOUCHED/FILTER

knob [9] is a further very useful control in live performance,

particularly if

TOUCH

TWEAK

functions are being used. It is used in conjunction with

the adjacent buttons

FILTER

and

LOCK

[8].

The knob’s function is to mimic that of the last-touched rotary encoder (this includes
Tweak mode). This continues to apply even when the currently-open menu or menu page
is changed. Thus if you have the Mix Menu open, and are using

RE6

to vary Noise Level,

you will ind that you can also vary Noise Level with the

Touched/Filter knob

. But if you

change to the Filter Menu, the

Touched/Filter knob

will assume control of Filter 1 Distor-

tion Amount (assuming the Filter Menu opens at Page 1) without any of the rotary encoders
being touched, because it remains assigned to mimic

RE6

. Think of

Touched/Filter

a “copy” of the last-touched rotary encoder when you are in parameter adjustment mode,
using the menus as normal.

If you are using either Tweak or Touch modes, then the rotary encoders are no longer avail-
able to control any sound parameters in the ‘normal’ way, but you can still control the last
parameter adjusted with the Touched/Filter knob. This functionality is always available, as
long as both

FILTER

and

LOCK

functions [8] are not enabled.

The Filter button

The parameter most often needed for dynamic adjustment is probably Filter 1 frequency,
and pressing the FILTER button [8] assigns control of this single parameter to the
Touched/Filter knob (hence its name!). Thus whatever else is going on, you can always
have control of your main ilter frequency.

The

TOUCHED/FILTER

knob’s function may be given control of Filter 1’s cut-off

frequency permanently, if wished. This can be set up on Page 1 of the Global
Menu with

RE6

. See page 37 for more details.

The Lock button

As described above, the function of the

TOUCHED/FILTER

knob will change with the

currently-selected menu, because the knob mimics a physical encoder rather than the
parameter the encoder is currently controlling. If

LOCK

is active, the parameter currently

being adjusted, and not the physical encoder, is assigned to the knob. Thus if there is a
parameter you want access to continuously, while perhaps retaining access to other pa-
rameters in other menus, using

LOCK

will ix control of that parameter to the

TOUCHED/

FILTER

knob and it will remain so until

LOCK

is deselected.

Note that some factory Patches include activation of the

LOCK

button; this will

be indicated by the button being illuminated. This will mean that a parameter is
already assigned to the

TOUCHED/FILTER
