6: Common synth functions
6:1 Arpeggiator (Strobe and Cypher only)
Arpeggiators turn a number of keys held down simultaneously into a repeated arpeggio sequence. They’re great for
interesting melodic textures, or to suggest a chord while only using 1 synth voice (especially at faster rates). This was a
very useful feature on monosynths incapable of any polyphony.
Cypher and Strobe both feature a built-in arpeggiator. Amber, on the other hand, is not a typical synth to use with an
arpeggiator, and therefore does not include one built into the synth. If you want to arpeggiate Amber, you can use Fusor’s
Animator device, which allows you to arpeggiate any combination of DCAM synths. It also offers many functions not
available in the more simple arpeggiator built into Strobe and Cypher.
Arpeggiator and LFO

arpeggiator
As in many classic analogue synth designs, the
arpeggiator in Strobe and Cypher is linked to the
LFO (LFO1 in Cypher’s case).
While the arpeggiator has its own independent
Rate
control, whether this rate is set as Hz or tempo-
based values depends on the state of the LFO’s
Sync
button.
Arpeggios are also linked to the LFO’s Swing and
PWM controls. Changing the LFO PWM changes the
length of each note generated by the arpeggiator,
while the LFO Swing amount can be used to create
swung arpeggios.
The LFO’s controls are described in section 7:5.
Arpeggiator and Keying controls
The behaviour of the arpeggiator is heavily dependent on the setting of the Priority parameter in
the Keying controls. Held notes are sequenced in the order dictated by the Priority parameter: the
sequence is played towards the note dictated by the parameter.
For example, if you want the sequence to follow the order in which you play the notes, set the Priority
control to ‘Newest’. This way, the first note you held down will always be the first in the arpeggiator
sequence, the second note you play will always play second, and so on. If you want the sequence
to go from low to high, set the priority to ‘Highest’.
The
Hold
button is very useful for indefinite arpeggio duration without having to keep keys held down.
It also allows you to use the arpeggiator as a rudimentary step-input performance sequencer by setting Priority to
‘Newest’ and playing one note after another. Each note is added into the note queue in the order in which it was played, a
sequence which is played back and repeated indefinitely. Please note that held notes are not saved with your preset!
See section 6:2 for further details of the Keying controls.
Arpeggiator controls
Power
Engaging the Power button turns on the arpeggiator. When disabled, the synth responds to keyboard input normally.
Rate
This control adjusts the speed of the arpeggiator sequence. While the Rate operates independently from the LFO rate, the
LFO’s Sync button must be enabled in order for the arpeggiator Rate parameter to be set in tempo-based values.
When the LFO Sync button is disabled, the arpeggiator Rate is set in hertz.
Note
The Note control dictates the order to play notes in the arpeggiator note queue, which in turn depends on the state of the
Priority
control in the Keying section. There are 4 settings:
Up Plays sequentially upwards through the note priority queue, from low priority to high
priority.
Dn (Down) Plays downwards through the note priority queue from high priority to low priority
UpDn
(Up and down) Plays up through to the end of the note priority queue (high priority) and then
backwards to the start (low priority).
Rand
(Random) Plays random notes from the note queue. In this mode, the Priority control setting is
irrelevant.
Range
This control dictates the number of octaves over which the arpeggio sequence is played.
