General
The NANOZWERG is a monophonic, analogue Synthesizermodule, which in its Design,
BUS-Power and CV/Gate-Voltage is fully compatible to a Doepfer A-100 Modularsystem.
Most of the Audio-Parameters can be adressed externaly by using the CV-Inputs. In
addition, this is also possible by using Midi or M-Bus. The Module contains all typical
elements of subtractive Synthesis and can be used for Bass-and Leadsounds aswell for
Effectnoises or as a Filterbox.
Set-Up
Connect the 10-pin cable to the corresponded 16-pin jack on the Doepfer mainframe bus
or the MIDI/CV circuit board. Supply voltage needs to be +/- 12 volts, 5-volt connections
are not required. The wattage is
ca. 150 mA
. The Modulesize is 24 TE = 121,9 mm.
ATTENTION:
Please, check for correct polarity! The colored side of the connector-
cable needs to point downwards so that the cable is not twisted.
Advice: The NANOZWERG is an analogue Synthesizermodule therefore it is
recommended to run for 10 min. after turning it on to „warm up“, to ensure solid tuning.
Oscillator-section (VCO & Sub OSC)
NANOZWERG features one VCO with an additional sub-oscillator. The VCO offers four
Waveform shapes, which can be selected by pressing
Wave
: triangle, saw tooth, rectangle
and impulse.
Octave
sets the base octave to 16’, 8’, 4’ or 2’.
Tune
controls the tuning
within a Range of +/- one octave.
The sub-oscillator generates a reactangle-wave one - two octaves below the VCO tuning.
Press
Sub OSC
to toggle in between the settings 1/2, 1/3, 1/4 or Noise. Alternatively the
reactangle signal can be replaced as a noise-generator.
Mixer
adjusts the balance between
VCO and SubOSC/Noise.
Use
VCF
In
to use any external audio-signal instead of the sub-oscillator.
The VCO can be modulated by the LFO. By turning
Mod VCO
to the left, the pitches of
VCO and Sub Osc are modulated. Turn it to the right and it will adress the symmetry
(pulse width) of the impulse-waveform. If its in middle position, Modulation will be
deactivated. Alternatively instead of the LFO you can use
Mod VCF In
for modulation.
.
The VCO can be synced by using the VCO sync input.
Glide
The trim controller
Glide
sets the length for a continuously glide of sequently played
notes. (Portamento)
Filter-section (VCF)
The 12-dB-Multimodefilter allows sonic shaping of oscillator, sub-oscillator and the
external audio-input.
It offers four modes, selectable by pressing
Select:
low-pass (LP), band-pass (BP), Band
Reject (Notch) and high-pass (HP).
The Cutoff frequency is adjusted using
Cutoff.
In addition this parameter can also be
controlled by different sources. The trim pot
Key Follow
sets the dependency between
cutoff and incoming notes on the MIDI-or Key CV-Input.
Contour
adjusts the control of the ADSR-Envelope 1 towards the cutoff frequency.
Turning it to the right has a positive influence, while turning it to left has negative
influence. By turning the knob into the centre modulation will be turned off.
Mod VCF
introduces a continuous modulation to the cutoff-frequency through the LFO.
Mod
VCF In CV
is a CV-input, which for example, can be adressed by a step-sequencer.
Resonance
sets the emphasis(Q-factor) of the filter at the current Cutoff-frequency. At its
maximum self-oscillation can be reached.
Amplifier (VCA)
The final part in the Signal path is a voltage-controlled amplifier. The VCA is triggered by
the ADSR-Envelope 2. The output signal goes out on
Audio Out
.
Envelopes (ADSR 1 + 2)
The envelope generator offers control for
Attack
-time,
Decay
-time,
Sustain
-level and
Release
-time. Release does not own its own knob, but can be set by the Decay-knob or
has a fixed release time. Pressing the Release-button can choose these two modes. Is the
LED turned off is the release –time fixed. The first three phases work while one note at the
MIDI-or Gate-input is active. The release-time starts after gate/note-signal has been
stopped. The envelope can be used external by using
ADSR1 Out
and
ADSR2 Out
.
Modulation-oscillator (LFO)
The LFO offers four waveform shapes: triangle saw tooth, rectangle and S/H (Sample &
Hold). The first three waveforms can stepless be switched by using the knob
Wave
.
Rate
sets the LFO’s frequency (speed) between approx. 4 seconds to ca.150 Hz. Both
Parameters can be changed through CV by using the inputs
LFO Rate In
and
LFO Wave
In
.
OneShot
activates a one-pass-mode, where the selected waveform is only played once,
after a note-trigger input is received.
MIDI/M-Bus
NANOZWERG receives MIDI-Notes over a range of five octaves (C1-C6). In addition it
accepts MIDI-Data for Pitch Wheels (+/-1 Semitone.). All Parameter can be controlled
external via Midi-controller The Midi Implementation can be seen in a separate document.
For the M-Bus there are two jacks on the bottom of the backside. One is connected to an
M-Bus-Output the other one to the next M-Bus-capable module. If the M-Bus is plugged,
Midi is turned off.
MIDI-Channel
To select a MIDI-Channel press
Select
of the Filter for ca. 2 Seconds till the Filter LEDs
run in a circuit. NANOZWERG is now waiting to receive the next Midi note and takes
over its channel. This also applies for the M-Bus.
