  • Page 3: Introduction

    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.
  • Page 4 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.
  • Page 5 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.
  • Page 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.

  • Page 7: Analog Filters

    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.

  • Page 8: Digital Filters

    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.
  • Page 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.

  • Page 10: Effect Processors

    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.
  • Page 11 -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.
  • Page 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.
  • Page 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.

  • Page 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.

  • Page 15: Add Mixers

    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.

  • Page 16: Ring Vca

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

  • Page 17: Outputs Module

    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.

  • Page 18: Envelopes

    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...

  • Page 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...

  • Page 20: Random Generators

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

  • Page 21: Triggers In

    Triggers In The signals applied to the 4 trigger input minijacks can trigger the 8 parts or control the sequencer clock (with divider), start/stop and reset. Signals below 1V are considered as a trigger off. Signals above 1V are considered as a trigger on. The trigger inputs can handle up to +/-45V.

  • Page 22: Triggers Out

    Triggers Out Any source can be sent to the 4 trigger output minijacks. The output range is 0V to 5 or 12V (settable via jumper).

  • Page 23: Cv In

    CV In The CV input minijacks does not have any settings, they can just be selected as modulation sources. The input range is -5V to +5V, and it has input protection, that will protect the circuits up to +/-45V. When controlling a part trigger note with a CV input, the input is scaled to 1V/oct.

  • Page 24: Cv Out

    CV Out The 4 CV output minijacks can output any source. An output offset can also be set, to make it possible to "program" external CV devices. The output range is -5V to +5V. When notes are selected as the source (notes from a connected MIDI keyboard, the touch screen keyboard and the sequencer), the CV outputs can be scaled to 1V/oct and 1.2V/oct.

  • Page 25: Connecting Modules

    Connecting Modules Connecting modules on Urano can be done in 3 different ways: Manually, via the module overview and automatically. The "manual" way, is to go to a modules audio or modulation input pages, and select the audio/modulation source and adjust the amount/level, using the 8 edit knobs.
  • Page 26 To connect modules on the overview page, first touch the module, for which you want to connect the inputs. Then touch the large SEL button. The SEL button will toggle between SEL (select module), MO1 (modulation page 1), MO2 (modulation page 2) and INP (audio inputs), every time you touch it.
  • Page 27 On these pages, the selected module (the module which inputs you are currently connecting), is indicated as a brown box with yellow text. The module(s) that are connected to the selected modules inputs, are indicated as dark blue boxes with light blue text. If the selected module is not included in the currently selected part, the text will be white instead of yellow.
  • Page 28 To insert a module in an audio chain, touch the modules PLC (Place) button. Urano will now jump to the Overview page and ask: "PLACE MODULE AFTER?". Now simply touch the module, that you would like the selected module to be placed after, and Urano will take care of all the connections.

  • Page 29: Sequencer

    Sequencer The Urano built in sequencer has 8 note tracks and 16 controller tracks. The note tracks are hard wired to the corresponding 8 parts. The controller tracks can be assigned as modulation and audio sources. Sequencer tracks can be recorded in real time, step time and in a TR way.
  • Page 30 Each note track can be up to 64 steps long, and resolution can be set from 1/64 to 1/2. Steps that are on, are indicated by cream white bars, steps that are off, are indicated by yellow/red bars. The note numbers and other values can be recorded in real and step time, and adjusted by the Edit Knobs, and directly by touching the screen.
  • Page 31 Each controller track can be up to 128 steps long, and resolution can be set from 1/64 to 1/2. Steps values are indicated by cream white bars. The step values can be recorded in real and step time, adjusted by the Edit Knobs, and directly by touching the screen. The transition between each step can be either stepped or smooth.

  • Page 32: Sample Record/Edit

    Sample Record/Edit Mono wav samplings can be recorded, imported, edited and played back by the oscillator modules. Stereo samplings can also be imported, but only the left channel will play back. Chop points can be imported or generated automatically and manually. Wavetables can be assembled...
  • Page 33 from samplings. The wavetable oscillators can also play back samplings directly, but assembling them from samplings will give more control over each single wave.

  • Page 34: Wavetable Editor

    In Nrm mode, the waveform drawing simply follows your finger, and you can draw any shapes easily. In Art mode, urano will generate artistic waveform patterns, as you draw. The patterns will vary after how high you place your finger on the screen, and if you draw forwards or backwards. It is possible to copy and paste single cycle waves.

  • Page 35: Connectivity

    Connectivity Urano connects to your analog gear via minijacks, and to other instruments via MIDI and jack connectors. -DC Jack: 2.1mm type with positive middle, 9V, 2A. -Audio In L/R: Main audio inputs. Standard line level. Are sent to the audio/modulation bus and the sample recorder.

  • Page 36: History

    History In the Christmas holidays 2020 I couldn't go anywhere on holidays, because of the pandemic travel restrictions, so I could right as well assemble a eurorack system. I did not have room for this on my studio desk, so I placed it on my computer desk. Soon I realized, that I needed a keyboard, a sequencer, and I would also like to have a sampler.
  • Page 37 I started out by putting a Tiny LD into a large plastic box, and added a slightly larger display, for better touch keyboard action. This was however too big for my desk, and felt quite impractical. So I was putting the Tiny LD back in a Tiny LD case.
  • Page 38 There wasn't room for all the required electronics in the small box, so not all of the minijack connectors worked (only the 4 trigger ins and outs worked), but it was ok for the Christmas holidays...
  • Page 39 While playing with it, I got more and more ideas, and one day it grew up!
