Main Features

• 4-note polyphonic Oscillators with continuously variable waveforms, wave-shape modulation,
fm and pwm which works on all waveforms.

• 4 high quality unique sounding analog-modelled bpf/lpf/hpf filters.

• Granulator effect.

• 5 distortion types.

• 4 LFO’s with continuously variable waveforms, waveshape modulation and rate modulation.

• 2 envelopes.

• Filter random generator.

• Various control sources for every parameter.

• Note randomizer.

• 32-step step sequencer which is MIDI-syncable, has one note track, one velocity track and one

controller track, has realtime transpose, and a keyboard (arpeggiator) mode, in which, you can
gate and transpose the sequence via a connected MIDI-keyboard.

• Storage of 128 sounds and sequences in eeproms. No need to worry about changing back-up
batteries.

• Direct MIDI-control of most parameters.

• Boxed small and compact – easily portable.

What is the deMOON?

The deMOON are a 4-note polyphonic virtual analogue filterbank synthesizer build on the latest
DSP technology. That it’s a filterbank synthesizer means, that instead of having only one or two
filters to treat the sound, like most synthesizers, it has four filters forming a bank. A filter are an
excellent tool for recreating the reflections that comes from an acoustic box, like a violin box or the
human mouth, but having only one filter limits the number of possible reflection emulations a lot.
Having four fully tweakable good-sounding filters, like on the deMOON, expands the creational
possibilities and the possibility to recreate acoustic instruments a lot.

Combine the filterbank with the same high-quality oscillators, a wicked granulator effect, a
distortion effect, four LFO’s and endless routing possibilities (the oscillators can also be selected as
modulators) and you got the deMOON’s strong sound engine.

Since it is small and very portable, a step-sequencer and a headphone output was added, so you can
let your creativity run loose with it everywhere. It’s even possible to power-supply it from a
standard 9V battery (a special cable is needed).

At top of it all a note-randomizer, that makes sequences unmechanical, was also added.

All of this is stuffed into a small and sturdy metal-box.

DeMOON front

Edit1 / Ctrl 2: When on the pattern select screen (the screen showing on the picture) and on the edit

page select screen, this knob transmits midi-controller 2 internally, and tweaks all
parameters, which has midi-controller 2 selected as modulation source.

When on a parameter edit screen, this knob adjusts the parameter showing at the left
of the screen.

Edit2 / Ctrl 3: When on the pattern select screen (the screen showing on the picture) and on the edit

page select screen, this knob transmits midi-controller 3 internally, and tweaks all
parameters, which has midi-controller 3 selected as modulation source.

When on a parameter edit screen, this knob adjusts the parameter showing at the
middle of the screen.

Play / Enter: This knob starts and stops the internal step sequencer. It also works as a midi note on

indicator – every time a midi note on, on the selected midi-channel, are received it
will light up.

When you select a new pattern, change the controller number for the sequencer
controller track or save a pattern, it will start blinking, and you will have to push it to
confirm.

Cursor (click) value: This knob navigates around, changes pattern, and changes various switch

functions on the parameter edit screens.

If the cursor is blinking, turning this knob will move the cursor. Pushing it will stop
the cursor from blinking, to change a value, or entering another screen.

If the cursor is not blinking, turning this knob, will change the value of the parameter,
where the cusor are located. Pushing it will get the cursor blinking to move it, or it
will enter another screen.

Volume: Changes the output volume on the stereo outputs.

Connections

9VDC: Connect the supplied power adaptor to the socket. The switch beside it are the power on/off

switch.

MIDI in: Connect this to the MIDI out of a MIDI transmitting device (MIDI keyboard,

sequencer, computer or whatever).

Output L/hp jack: This is the left line output, and needs to be amplified. Connect it to an amplifier

or a mixer. It also doubles as a stereo headphone jack.

Output R jack: This is the right line output, and needs to be amplified. Connect it to an amplifier

or a mixer. LEAVE THIS UNCONNECTED IF YOU CONNECT HEADPHONES
TO THE L/HP JACK.

How to get around on the DeMOON

Some main rules: If the cursor is blinking, you can move it by turning the cursor(click)value

encoder.
If the cursor is not blinking, you can change the value of the parameter the cursor are located below,
by turning the cursor(click)value encoder.
By pushing the cursor(click)value encoder, you change the cursor from blinking to not-blinking and
vice versa.

The pattern/sound select page

This is the deMOON main page. Every time you turn on your deMOON, it will for a short while
write: ”Gotharman’s deMoon”, and right after that, it will go to this screen.

On the top of the display it writes the name of the selected pattern/sound. It remembers what pattern
was selected, when it was turned off, and goes to that pattern when it is turned on again.

On the bottom of the display it writes the selected pattern bank and number. The deMOON has
eight banks (A-H) with each 16 sounds (128 in all). The number shown in paranthes, are the midi
program change number you will have to transmit to the deMOON, to select this pattern, from an
external midi-device.

To change pattern: If the cursor is not blinking, push the cursor(click)value encoder, to make the
cursor blink. Rotate the cursor(click)value encoder in either direction to place the cursor under the
letter, if you want to change the bank number, or the number if you want to change the pattern
number. Push the cursor(click)value encoder, so the cursor is not blinking. Rotate the
cursor(click)value encoder to select the pattern you want. It will write the pattern name on the top of
the display. The play/enter knob will now start to blink. Push the play/enter knob to confirm change
to the selected pattern.

The Edit pages

NOTICE: The edits you do, are not automatically stored in memory. If you would like to keep your

creation, you wil have to SAVE the pattern. How to do that, are explained later in this section.

How to enter the edit pages from the pattern select page:

If the cursor is not blinking, push the cursor(click)value encoder, so the cursor is blinking. Rotate
the cursor(click)value encoder until the cursor is located under ”Edit”. Push the cursor(click)value
encoder. Now this screen should appear:

and the cursor are blinking. If you want to exit back to the pattern/sound select screen, rotate the
cursor(click)value encoder so the cusor locates under eXit, and push it.

If you, on the other hand, wants to start editing some sounds and/or sequences, make sure that the
cursor is located under the number, and push the cursor(click)value encoder. Now the cursor will
stop blinking, and by rotating the cursor(click)value encoder, you can now select among various
edit pages. Pushing the cursor(click)value encoder again, enters the edit page.

Inside an edit page, it might look like this:

When you enters an edit page, the cursor are blinking. By placing the cursor under the number in
the upper left corner of the display, and pushing the cursor(click)value encoder you can select
among various edit pages in the selected edit group. By placing the cursor under the ”X” and
pushing the cursor(click)value encoder, you will exit to the edit page group select page.
The two parameters shown in the left and in the middle of the display are changed by rotating the
edit1 and edit2 knobs. The parameter to the right is changed by moving the cursor to it, and use the
cursor(click)value encoder.
