SHARED SEQUENCER PARAMETERS

The setting of the

SEQ OCT

function is shared by both Sequencers; it cannot be set individually.

SEQ OCT

This function specifies the octave range available for each of the

STEP

knobs in

the sequencers. There are three values for this parameter. Repeatedly pressing
the

SEQ OCT

button will cycle through the available options, with an LED

indicating the current selection.

This option provides five octaves above and five octaves below the current

VCO FREQ

knob value for each individual step.

This option provides two octaves above and two octaves below the current

VCO FREQ

knob value for each individual step.

This option provides one octave above and one octave below the current

VCO FREQ

knob value for each individual step.

NOTE:

The sequencers cannot internally modulate the frequency of the VCOs any higher than 10k Hz (approximately).

For full use of the

5 Sequencer Octave range, set the

VCO 1 FREQ

and

VCO 2 FREQ

knobs fully counter-clockwise

at the Middle C position. In addition, subharmonic content cannot be accurately generated above 10k Hz. It is
important to be aware of these details because the VCO frequency setting and individual Sequencer Step values
are summed with the VCO CV inputs, which can drive the VCOs far above 10k Hz.

NOTE:

By default, the

SEQ 1

and

SEQ 2

output jacks will output a control voltage that reflects the current Seq Oct

settings. This behavior can be disengaged by pressing and holding the

SEQ OCT

button until the LED flashes, at

which point the

SEQ 1

and

SEQ 2

output jacks will output at

5, regardless of the Seq Oct setting. In this mode,

the oscillators will continue to respect the Seq Oct settings. Press and hold the

SEQ OCT

button until the LED

stops flashing to return to the default.

TRANSPORT CONTROLS

This set of controls affect the sequencers, the rhythm generators,
envelope behavior, as well as handling of internal and external
clock signals.

PLAY

The

PLAY

button starts and stops the playback of the sequencers. When the

PLAY

button is lit, the sequencers are playing. When the

PLAY

button is unlit,

playback has stopped.

NOTE:

This button will also start and stop the rhythm generators, and will stop (when

unlit) the clock signal sent from the

CLOCK

output jack.

TRIGGER

The function of the

TRIGGER

button is determined by the

button

(page 29).

If the

button is On (lit), pressing the

TRIGGER

button will instantly restart

the envelope generators (VCF EG and VCA EG) without waiting for the next
step of the sequencer(s). Note that the EGs will

NOT

restart if they are currently

in the Attack stage.
