Introduction
Urano is a modular synthesizer with memory. All connections between modules, module settings,
sequences and sample assignments can be memorized for instant recall.
Like many other Gotharman instruments, each preset contains 2 versions of the preset, that can
be morphed between. With one knob, you can morph all the settings of a complete modular
system!
It will also hold all your samplings and wavetables in memory, even after a power recycle.
And it connects to your Eurorack...
Unlike the Anamono X, which had 2 separate bus systems, one for audio and one for modulation,
Urano only has one bus, that handles both audio and modulation, so everything can be connected
to everything.
The build-in modules:
- 8 Oscillators - Waveforms, noise, drum oscillators, samplings, wavetables.
-Up to 4 analog filters . Compatible with the Gotharman filter board system. Comes with 4 analog
filters installed as standard.
- 8 digital filters - 27 filter types. Standard filters, triple filters, sharp filters, tube filters...
- 8 VCA's - with ADSR envelope, various curves and a clip parameter. Can be trigged by any
source.
- 8 Effects Processors - Many of the LD effects plus a new reverb, a wavefolder and some new
pitch effects.
- 8 LFO's - With variable waveform and curve. Key syncable.
- 8 Envelopes - ADSR + decay envelope with loop options. Can be trigged by any source.
-5 Random Generators .
- 4 Ring VCA's .
- 2 Mixer modules , that can add extra inputs to any module.
- Output module - Sends up to 8 sources to the outputs, and handles the stereo panning.
- Trigger Input module - Assign the trigger inputs to parts and sequencer functions.
- Trigger Output module - Sends any sources to the trigger outputs.
- CV Output module - Send any sources to the CV outputs. Can scale to 1V/oct and 1.2V/oct.

Connecting Modules
Urano has different ways of connecting the modules. They can be connected manually, by setting
the source and the amount, for audio and modulation, by turning a knob, they can be connected
via an overview module grid, using the touch interface, and modules in the audio path, can be
added and removed into/from the signal chain, by using Urano's auto functions.
8 Parts
The modules can be arranged into 8 parts, to make it possible to make tracks on Urano with 8
different sounds. Any module can be used by any part, and the modules can even be used by
multiple parts at the same time.
On an initialized preset, the modules are arranged in the 8 parts, each with oscillator, filter, VCA,
effects processor and envelope, to make it possible to make tracks instantly. In the standard
configuration, part 1-4 also has an analog filter included.
Sequencer
An LD3 style sequencer is available to compose music with the parts. It has 8 note tracks and 16
controller tracks.
Sample recorder/editor
Samples can be recorded from the audio inputs and outputs, imported via USB, and edited.
Wavetable editor
Not only can the Urano oscillators 1-4 play back wavetables. Urano also has a wavetable editor
built in, where you can edit and draw wavetables on the touch screen, and, of course, save these.
Connectivity
Urano can interface with other instruments via MIDI and minijack connectors.
Touch display
It comes with a 4.3" touch display. Most operations can be performed via knobs and buttons, but
sometimes the touch display can help speeding up the workflow. The touch interface on
Gotharman instruments work in a very simple way, without any annoying "touch gestures".
Solid
Built to last in a steel box with extruded aluminium sides. All powdercoated with a "Black Sand"
finish, that is very resistant to scratches and dust. All knobs, buttons and connectors are of the
highest quality.

OSC –Oscillators
The 8 Urano oscillators can run in several different modes, for maximum flexibility. The outputs of
the oscillators can be connected to any audio and modulation inputs.
The modes:
-Type1 : Morphs between sine wave, triangle wave, sawtooth wave, pulse wave and feedback
wave. PW works on all waveforms. Pitch, wave. PW and portamento can be modulated. This
oscillator type has a fat sound, without any aliasing.
-Type2 : Morphs between sine wave, triangle wave, sawtooth wave, pulse wave and feedback
wave. PW works on all waveforms. Pitch, wave, PW and portamento can be modulated. This
oscillator type has a more organic sound than type1, and the pitch tracking on the higher notes are
more smooth and precise.
-Reso: Resonator oscillator. An oscillator that is partly generated by a special Gotharman
engineered filter, that has multiple resonances in its feedback path. Great for emulating string
instruments, and for new synthetic sounds. Morphs between sine wave, triangle wave, sawtooth
wave, pulse wave and feedback wave. PW works on all waveforms and Reso, the amount of
resonances, can be adjusted. Pitch, wave, reso, PW and portamento can be modulated.
-Perc, Prc2, Prc3 : Percussion oscillators. Special oscillators for creating drum sound. Each of the 3
models has different characteristics. Detune, attack, noise amount, PW and portamento can be
adjusted and modulated.

6
-Cymb, Cym2 : Cymbal oscillators. Special oscillators for creating hihat, cymbal and other metallic
sounds. Cym2 are a bit more aggressive than Cymb. Detune, FM, PW and portamento can be
adjusted and modulated.
-Clap: Hand Clap oscillator. A noise source controlled by a special hand clap envelope, to emulate
the classic hand clap sounds. Tune, detune, PW, clap envelope amount and portamento can be
adjusted and modulated.
-Smp: Sample Playback. Pitch, sample start, sample length, chop point select and portamento can
be adjusted and modulated.
-ChKy: Chopped sample keyboard. The chop points of the selected sampling, will be spread over
the keyboard. Pitch, sample start, sample length, chop point select and portamento can be
adjusted and modulated.
-Noise: Pitched noise generator. Pitch and PW can be adjusted and modulated.
-Wtbl: Wavetable oscillator (Only oscillator 1-4). Plays back 32 KB wavetables with 8 or 64 single
cycle waveforms. Morphs smoothly between each cycle. WaveX, WaveY, Metal and portamento
can be adjusted and modulated.

VCF - Analog Filters
Urano has 2 analog filter board slots. These are compatible with the whole line of Gotharman filter
boards, and also with some new dual line filter boards, made especially for Urano. Urano comes
with 2 dual line analog filter boards installed, to give it a total of 4 analog filters. VCF1 and 3 are a
new very resonant feedforward filter design. VCF2 are a multi mode filter with 8 different modes,
based on the VCF10 filter board with SSI2140. VCF4 are a SSI2140 lowpass filter. And of course
Gotharman's G-Ray, intermodulation feedback, are available for every analog filter. Most
parameters can be modulated.

8
DGF - Digital Gotharman Filters
The 8 digital filters on Urano have 27 different filter types to choose from. Cutoff frequency,
resonance and filter levels can be adjusted and modulated.
Filter Types:
-SvfLp : 12 dB very smooth lowpass filter.
-SvfBp : 6 dB very smooth bandpass filter.
-SvfHp : 12 dB very smooth highpass filter.
-SvfNt : 6 dB very smooth band eliminate filter.
-ShpLp : 12 dB lowpass filter with a sharp response.
-ShpHp : 12 dB highpass filter with a sharp response.
-3peak : 3 bandpass filters with a smooth response.
-3shp : Sharp triple filters with narrow frequency bands.
-LPF1 : Lowpass filter with emphasis on the bass response. Has a weak high frequency response.
-LPF2 : Lowpass filter with a strong bass response, and better high frequency response than LPF1.
-LPF3 : Lowpass filter that has a bit less character than LPF 1 and 2, but has a sharper resonance.
-LPF4 : Lowpass filter with a bit more emphasis in the bass area.
-LPF5 : Lowpass filter with a more soft character.
-LPF6 : Lowpass filter with soft character, that has a more sharp resonance.
-LPF7 : Thin and sharp lowpass filter.

9
-BPF1 : Pretty basic bandpass filter.
-BPF2 : Bandpass filter with improved bass response and a strong, almost distorted character.
-BPF3 : Sharp bandpass filter.
-BPF4 : Bandpass filter that is even sharper than BPF3.
-BPF5 : Bandpass filter that is even more sharp than BPF4.
-BPF6 : Thin and sharp bandpass filter.
-BPF7 : Thin bandpass filter, that is a bit sharper than BPF6.
-TUB1, TUB2, TUB3, TUB4, TUB5 : Tube emulation filters with a very nonlinear and distorting
response.

10
EFX - Effect Processors
Urano has 8 effect processors. Effect 1 to 6 has more effect types to choose from, than effect 7
and 8, but effect 7 and 8 has a larger RAM buffer, so these are better suited for reverbs and
delays. Most parameters can be modulated. Urano has many of the classic deFormer effect, but
also some new ones, like a wavefolder, a new reverb, and some new pitch effects.
Effect 1 to 6 types:
-Chorus : Gotharman's special chorus with an added Deep parameter, that adds space to the
chorus.
-Resonator : Simulates the resonances that comes, if a sound goes through a small box. Urano’s
resonators are synthetic, with more focus on making sounds, than on simulating actual boxes.
-Distortion : 5 types: Valve, Sine, Fuzz, Xdis, Asym.
-Bit Crush : Lowers the sample rate and the bit resolution of the sound, to obtain lo-fi effects.
-PitchShift : Shift the pitch of the sound up to 4 octaves up or down, without changing the time
resolution or “tempo” of the sound. Adjustable sense.
-Stretcher: Tries to time stretch the input signal, while at the same time keeping up with it.
Impossible? Yes, indeed :-)
-FM : Adds self-FM to the input signal in +/- 1 octave, +/- 2 octaves or +/- 4 octaves ranges.

11
-Sample Pitch : Changes the pitch of a sampling, without changing the length, using granular
technology. It is possible to set the size of each pitch grain, to generate great granular effects. This
effect has to be trigged from any of the parts, in order to function properly. It will work on
external signals, but it still needs to be trigged by a part.
-SamplePitch V2: NEW! A pitchshifter that is degrading the sound. A Peak parameter are
available, that alters the formants, and a Warp parameter will warp the signal into another
dimension.
-Roto Pitch: NEW! Rotating pitch shifter. This is not as smooth as the same effect in processors 7
and 8, but still usable for some weird pitch effects.
-Variator : Creates new variations of the input signal. Both pitch and rhythmic variations.
-PitchShaper : 1 input version of Gotharman's special Pitch Shaper, that forces an audio signal to
play back at a specific pitch, determined by an adjustable frequency.
-PitchShaper2 : This is a dual input PitchShaper. The pitch of the signal applied to input 1, is pitch
matched to the signal applied to input 2. When changing the pitch of the pitch matched signal, the
waveform on the effect output will change, still matched to the pitch of input 2. It is also possible
for the signal applied to input 1, to affect the output pitch, by turning the Vari parameter up.
-Time Stretch : This effect is able to change the length of the input signal, almost without changing
the pitch. Old fashioned time stretch done in realtime, that can be applied even to live input
signals! It is also possible to change the pitch if desired, and it is possible to trigger this effect, for
bigger precision.
-Filter : The original digital Gotharman filters from the deFormer series. 16 filter types.
-Triple BPF: NEW! This is the same triple filter as found in the DGF section, but with an added
"Gates" parameter, that "digitalizes" the filter for some special effects.
-WaveFolder: NEW! A dual Wavefolder.
-FAT : Adds up to 3 layers of the sound to itself, and it is possible to adjust the phase of these, and
to select whether the effect sound should be boosted or just layered.
-EQ : A parametric EQ with different characteristics.
-EQ2 : A parametric EQ with different characteristics than EQ1.
-OverShifter : A kind of frequency shifter, that can shift the frequency bands of the input signal up,
and add feedback and ring effects.
-Bass Enhancer : Enhances the bass area of the sounds, that goes through it, and adds some boom
to these.
- Compressor : Damps audio signals that are above a settable level, in order to make the signal less
dynamic, and easier to record.
-Expandor : Gains audio signals that are above a settable level, in order to add more kick to
sounds.
-Delay1 : Delay with time and feedback controls, plus Gotharman's Deep and Xfade controls. Deep
adds space to the delay. The Xfade control on this delay, creates valleys between the delay taps.
The more it is turned up, the more time the valleys takes up.

12
- Roto Delay : This is a 2 tap delay, that is constantly crossfading between the 2 taps. When the
Xfade control is turned down, the crossfading is rough, the more it is turned up, the more smooth
the crossfading gets. Other controls are the same as the first delay.
-Bright Delay : First delay, but with a brighter sound, created by a resonator.
-Br Roto Delay : Roto delay, but with a brighter sound, created by a resonator.

13
Effect 7 and 8 types:
-Delay1 : Delay with time and feedback controls, plus Gotharman's Deep, Size, Beam and Xfade
controls. Deep adds space to the delay, Size makes the playback range more narrow than the input
recording range, and beam beams the delay to previously unknown places. The Xfade control on
this delay, creates valleys between the delay taps. The more it is turned up, the more time the
valleys takes up.
-Roto Delay : This is a 2 tap delay, that is constantly crossfading between the 2 taps. When the
Xfade control is turned down, the crossfading is rough, the more it is turned up, the more smooth
the crossfading gets. Other controls are the same as the first delay.
-Bright Delay : First delay, but with a brighter sound, created by a resonator.
-Br Roto Delay : Roto delay, but with a brighter sound, created by a resonator.
-Granulator SQ : Cuts the input signal up in grains, that can be re-arranged. This granulator is
synced to the sequencer.
-Variator : Creates new variations of the input signal. Both pitch and rhythmic variations.
-Reverb: NEW! A newly designed reverb effect, that is more smooth, and has simplified
parameters, for easier programming.
-Granulator : Cuts the input signal up in grains, that can be re-arranged, using the step values of a
selectable controller sequencer track. This is the granulator that was named “AnaGran” in earlier
Gotharman instruments. Unlike the Granulator SQ, this is not synced to the sequencer. It plays
back one grain, and then it immediately advances to the next grain.
-Xfade Granulator : Cuts the input signal up in grains, that can be re-arranged, using the step
values of a selectable controller sequencer track. This granulator plays back one grain, and then it
crossfades to the next grain. It is also possible to adjust and modulate the pitch of the granular
sequence, using any modulation source.
-Abstruct0 : This effect constantly records the audio applied to its input, in a time interval
determined by a ”Rec” parameter. It uses 2 ”playback heads” to play back the recorded audio.
Each of these playback heads can be switched on and off, and the playback length can be adjusted
for each of them. Every time a head has played back the adjusted amount of time, it jumps to a
new random location of the recorded piece, and starts play back again. The playback pitch of head
2 can be adjusted.
-Time Stretch : This effect is able to change the length of the input signal, almost without changing
the pitch. Old fashioned time stretch done in realtime, that can be applied even to live input
signals! It is also possible to change the pitch if desired, and it is possible to trigger this effect, for
bigger precision.
-Roto Pitch: NEW! Rotating pitch shifter, that can create smooth echoing pitch shifts.

14
VCA
Urano has 8 VCA's with built-in ADSR Envelopes and an envelope Clip parameter, that adds more
punch to the VCA. The VCA’s can run in various linear and logarithmic modes, and the envelope
time can be timed by 4, for long envelope times. The VCA envelopes can be trigged by any sources.
The A, D, R and output level parameters can be modulated.

15
MIX –Add Mixers
Every modules that has audio inputs, has 3 of these - DGF, VCF, VCA, EFX. If more audio inputs are
needed, one of two extra "add mixers" can be added, by using the "Add" parameter. Adding an
Add Mixer to a module, will add 4 extra audio inputs - 7 inputs in total. The same Add Mixer can
be used in multiple modules, if you would like to add the same signals to each of these.

16
RING VCA
Urano has 4 Ring VCA's, which can be used as both VCA's and Ring Modulators.

17
Outputs Module
In the output module, signals can be assigned and routed to the different audio outputs. Panning
of sounds and pan modulation is also done here.
PLEASE NOTICE: In the standard configuration, with 4 analog filters installed, the signals sent to
VCF3 and 4, are also sent to audio out 3 and 4, so signals from the output module are not sent to
these. Signals can only be sent to output 3 and 4, if single line filter boards are installed.

18
ENV –Envelopes
Urano has 8 envelope modules, each with an ADSR envelope and a Decay envelope. The ADSR
envelope can run in various linear and logarithmic modes, the envelope time can be timed by 4,
for long envelope times, and the ADS segment can be looped. The envelopes can be trigged by any
sources. The A, D, R and output amount parameters can be modulated.

19
LFO
Urano has 8 LFO's with a waveform that morphs from triangle to sawtooth to pulse to FM waves.
Curve can be adjusted from logarithmic to linear to exponential. The LFO's can be key synced, and
a one-shot mode is available, for using the LFO's as envelopes. The Rate, Wave and Curve
parameters can be modulated.

20
Random Generators
5 Random Generators are available. Every time these are trigged, they put out a new random
value. Triggers can be any source.
