frequency rate (from 0.01 Hz to

100 Hz). In

free mode, all the slid-

ers dene the frequency rate. In

quad and phase mode, sliders 2–4

dene the phase shift. In

divide

mode, sliders 2–4 dene the multi-

plication of the master period.

To manually set the frequency

rate more precisely, use the

zoom

mode, described in paragraph 6.

The

frq/ph/div socket

allows

the corresponding slider param-

eter to be voltage controlled (1V/

oct.). Expected voltage amplitude

is 10 V and the extended frequency

range 53 minutes to 500 Hz may

be obtained.

side note: Going

above 100 Hz you can expect the

waveforms to be less precise and

the output amplitude lowered.

The

reset/sync socket

is an

user-dened trigger input that

can serve as either cycle reset or

external tempo sync. Details to be

found in paragraph 5.

The

sine socket

outputs a sine

waveform (–5 to +5 V). In quad

and phase modes, the sines are

shifted in relation to each other.

The

saw/asgn socket

outputs

either a default upwards saw

waveform (–5 to +5 V) or one

of the user-selectable shapes,

described in paragraph 7.

The

square socket

outputs a

square waveform (–5 to +5 V).

The LFO sync mode toggle section

allows you to set the four oscil-

lators to run free or synced to the

master, as follows:

1. FREE LFO MODE

To enter this mode, click the

central button until the red,

free

LED lights up.

Now, any of the four LFOs works

independently.

2. QUADRATURE LFO MODE

Click the central button until the

yellow,

quad LED lights up.

The rst LFO is a master

controlling the frequency for all

the remaining LFOs, then each

subsequent LFO generates a wave

that is 90º shifted in relation to the

preceding one (90º, 180º, 270º).

In this mode, sliders and control

inputs for LFOs 2–4 are not active.

3. PHASE LFO MODE

Click the central button until the

yellow,

phase LED lights up.

Similar to quadrature mode, but

allows the phase shift to be set

arbitrarily.

Sliders 2–4 and

freq inputs are

active.

reset/sync 2–4 inputs are

not active in this mode.

a tip: In phase mode, patch one of

the LFOs to control the phase shift

of another. Stacking 2 or more

LFOs results in very complex,

interesting waveforms.

4. DIVIDE LFO MODE

Click the central button until the

blue,

divide LED lights up.

LFOs 2–4 are synced to the rst

(master) one and their frequency

rates are subdivided. Sliders 2–4

dene the multiplication ratio.

Resulting cycle rates can be 2, 3, 4,

8, 16 or 32 times slower than the

primary, master LFO’s cycle.

reset/sync 2–4 inputs are not

active in this mode.

5. RESET & SYNC MODE

The reset/sync input can serve

two different purposes.

reset mode, an incoming trig-

ger impulse resets the LFO cycle to

zero state (hard sync).

sync mode (default setting) the

LFO frequency rate can be slaved

to an external clock source or

tapped via manual gate.

These modes are selectable by

the jumper

on the back (no

jumper for

reset, jumper present

for

sync).

6. ZOOM MODE

Hold the central button for a

second until the current mode LED

starts to blink. Now you can adjust

the frequency rates much more

precisely, around the central value

—as the slider travel is upscaled.

Hold the button again to leave the

zoom mode.

7. ASSIGNABLE WAVEFORMS

The saw/asgn output can be

altered to provide other waveform

types as well. In the default rm-

ware, there are four waveform

types to choose from: saw up-

wards, saw downwards, triangle

and trapezoid. To assign the de-

sired waveform, use the jumpers

cluster

on the back, according

to the legend printed nearby.

FIRMWARE UPDATES VIA USB

This does not end here. There are

some alternate rmware revisions

planned, allowing i.e. different

waveforms to be assigned. The

popular Mini USB standard port

allows an easy and straightfor-

ward update procedure. Detailed

instructions will be bundled with

the rmware package avail-

able online.

caution! Orient the

update jumper

in the ‘on’ state

(jumping the left 2 pins) only while

updating the rmware! Otherwise

orient to the ‘off’ state (the right

two pins).
