keep me informed!The Keyboards: The Core of Expression
Uranograph's dual keyboards layout is more than just an input devices—it's the expressive heart of the instrument, offering an intuitive yet deeply responsive interface for performance and sound exploration. Their stainless steel touch plates provide an ultra-sensitive playing experience, responding to the most delicate gestures with precision and nuance. Unlike conventional mechanical keybeds, Uranograph's capacitive surface allows immediate, fluid articulation, enabling new microtonal performance, dynamic phrasing, and real-time sound shaping possibilities.
Velocity & Aftertouch Sensitivity
Uranograph's keyboard is highly responsive to touch, velocity, and aftertouch pressure.
Each press translates into a continuous, organic sound variation, making it possible to shape phrases naturally, much like on stringed or wind instruments.
By default, pressure is routed to the instrument's VCA/filter, and the envelope sustains level volume.
An additional routing can be set to send the intensity of pressure to whatever other parameters you prefer, a dedicated knob is also implemented for instant control of the amount of this.
This continuous pressure-sensitive surface offers a playing experience closer to acoustic instruments, bridging the gap between electronic synthesis and natural musical expression.
Microtonal Flexibility & Custom Tuning
Uranograph notes output takes advantage of a series of prepared Keyboard, where each key can be easily assigned to any pitch or pure frequency, offering complete keyboard design and tuning flexibility.
Whether adhering to traditional Western tuning, exploring Arabic maqams, Indian ragas, Just Intonation, or experimental microtonal divisions, Uranograph provides an expansive range of tonal possibilities.
Preloaded with 50+ keyboard layoutsCustomizable keyboards allow users to design and store personalized layouts.Instant recall ensures seamless transitions between different tonal systems.
This adaptability makes Uranograph an ideal instrument for non-standard tuning, enabling deep engagement with diverse musical traditions and avant-garde soundscapes.
Control Keyboard: Real-Time Sound Shaping
Beyond pitch control, Uranograph features a dedicated control keyboard designed for dynamic, hands-on sound transformation. Unlike traditional mod wheels or faders, this touch-based control surface enables intuitive, real-time interaction with synthesis parameters, allowing for expressive, gestural modulation.The control keyboard is divided into three functional sections: Articulation, Octave Shift, and ModKeys.Three dedicated articulation plates provide instant access to advanced phrasing techniques and canonic musical articulations found in stringed instruments: glissando, trillo, and staccato.
Glissando: Enables smooth pitch slides between notesTrillo: Rapidly alternates between notesStaccato: Shortens note duration, creating a percussive attackEach articulation can be activated momentarily (by holding the plate) or latched (by tapping once), offering precise control over phrasing. This flexibility allows musicians to engage articulations selectively, shaping expression dynamically within a phrase. They can introduce variation within a note and the successive one or as a general character of the part.Three faders are implemented on the panel to quickly change the articulation's behaviors. Four ModKeys serve as fully assignable, pressure-sensitive controllers for precise real-time modulation of synthesis parameters
Each plate dynamically responds to pressure, enabling simultaneous control over multiple parameters.By integrating expressive modulation gestures with the performance keyboard, players can shape fluid, evolving textures that respond organically to touch—enhancing expressivity and immediacy in synthesis.
ModKey destinations and maximum values can be adjusted in the menu and stored during pattern changes.
Octave Shift & Bend Functionality
At the bottom, two integrated octave shift plates provide instant transposition, allowing players to increase or decrease the octave range in momentary or latching modes.
Momentary Mode: Holding a plate temporarily shifts the octave.
Latching Mode: Tapping once locks the new octave until changed.
Bend Mode: Pressing both octave plates simultaneously activates the pitch bend feature, allowing for fluid and expressive pitch manipulation, similar to bending notes on stringed instruments.
Advanced Harmonic and Phase Manipulation
Synthesis Core
Uranograph's core is built on additive and phase morphing synthesis, offering an innovative approach to shaping its five oscillators.The primary sound source is a core oscillator that starts as a pure sine wave and transforms through multiple synthesis techniques, generating a spectrum of timbres from warm, organic tones to sharp, digital textures.Uranograph provides multiple methods to modify the primary sine wave, introducing even and odd harmonics and sidebands, shaping both harmonic and inharmonic spectra. By altering the phase of a sine wave without changing its fundamental frequency, Uranograph transforms simple waveforms into dynamically evolving textures that range from warm and bell-like to metallic and aggressive.
Size (Phase Warping & Spectral Expansion): Stretches waveforms, altering harmonics similar to pulse-width modulation.
Tilt (Asymmetric Amplitude Distortion): Inspired by the Casio CZ series, this phase distortion skews waveforms asymmetrically, generating sounds from soft and vocal-like to harsh and metallic.
Fold (Wave Folding): Nonlinear reflection of signals creates a harmonic-rich spectrum, akin to West Coast synthesis.
Primary controls:-
The core oscillator can be split and harmonized into three voices, each following a chromatically quantized deviation from the main frequency set by the keyboard.
This creates chord-like voicings, which are ideal for harmonic layering and ensemble effects. This enables Uranograph to function more as a harmonizer effect than a standard polyphonic synth.
The three voices are direct copies of the primary waveform and inherit all parameter modifications from the panel, ensuring a cohesive harmonic response across all voices.
-
The central core oscillator works in a dual-spectrum configuration with a dedicated sub-octave oscillator.
While the core oscillator's rich harmonics define the upper-frequency spectrum, the sub-generator reinforces lower frequencies, ensuring depth and body.
Waveforms: Sine, saw, and square waveforms selectable via a switch.
Selectable Sub Frequencies: unison, one or two octave below
-
Completing the architecture, a dedicated modulation oscillator serves as either an additional fifth voice or a modulation source.
Frequency follows the keyboard, but its base rate is controlled via the speed knob.
The frequency range is 0.001 Hz to 3,000 Hz, allowing for both slow-evolving modulation and audio rate for rich spectral transformations.
Waveforms: Sine, saw, and random noise selectable via a dedicated switch.
A dedicated modulation amount knob determines how the modulator interacts with different synthesis parameters selected through a rotary potentiometer: AM, FM, Size, Tilt, Fold, or mix.
This final layer opens the door to classic and unconventional sonic textures, making the Uranograph a versatile tool for sound design exploration and experimental synthesis.
-
In Uranograph's additive and phase-morphing synthesis architecture, the filter plays a different role than in traditional subtractive synthesis. Unlike classic synths where filtering is crucial for shaping harmonics, Uranograph's core oscillators inherently define the harmonic content through their phase manipulation and additive processes. As a result, harmonic reduction and spectral shaping are already embedded in the sound generation itself.
After the summation of the core oscillator, SUB, and MOD, Uranograph features the FiltAmp, a versatile circuit that functions as either a VCA or a Low Pass Gate (LPG)/VCA hybrid.
The Character controls the resonance, ranging from subtle warmth to highly aggressive self-oscillation, adding an organic response to dynamic playing.ento
Varimode modulator
While Uranograph is centered around tactile control and expressive interaction, it also features an automatic cycling modulator for continuous dynamic shaping. More than just a standard LFO, the VariMode Modulator is a multi-functional modulation engine. It offers a wide range of modulation-based effects that can be loaded into six assignable slots on the panel.Each preset can have its unique selection of modulation types, making the loaded slots customizable per patch. The selection and switching between these modulation modes are done effortlessly via the rotary selector, allowing performers to change modulation effects dynamically on the fly.Parameter Knob: Adjusts the primary function of the selected VariMode modulation effect.Amount Knob: Controls the intensity of modulation applied to the assigned destination.
Available Modulation Modes
The VariMode Modulator offers a diverse set of modulation sources and effects, including:
Sub Volume Saw LFO – Modulates sub-oscillator amplitude with a saw wave LFO.
Pitch Envelope – route the envelope modulation to pitch, useful for pluck-like textures.
Harmonizer Swell – Smoothly auto-swell harmonization levels for evolving chord dynamics.
Size Sine LFO – Controls oscillator phase warping using a sine wave LFO.
Tilt Sine LFO – Introduces subtle to extreme phase distortion with sine wave modulation.
Core Fold Sine LFO – Modulates wave folding depth dynamically.
Core Morpher – Randomly influences multiple synthesis parameters for evolving textures.
Vibrato – Classic pitch modulation for expressive micro-pitch fluctuations.
Tremolo - Classic AM modulation
Delay Mod – Modulates delay time for evolving rhythmic effects.
Reverb Sidechain – Adds dynamic ducking to the reverb for cleaner spatial control.
Overdrive – add saturation intensity for dynamic tonal shaping.
Amplitude Ripple – pulsations in volume that evolve based on key pressure.
More will come in futures update.Assignment of VariMode to the six slots (A, B, C, D, E, F) can be done through the menu and is saved through preset changes.FX
Uranograph's core sound engine is enhanced by a suite of tailored DSP effects, meticulously designed to shape and refine every aspect of its timbres. These effects are fully integrated into the synthesis architecture, ensuring seamless interaction with the instrument's dynamic sound design. From spatial depth to harmonic reinforcement, these tools expand the Uranograph's sonic capabilities, offering immersive and evolving textures.
Uranograph's stereo delay system is engineered for rhythmic enhancement and spectral manipulation, seamlessly blending traditional echo effects with Karplus-Strong-style resonation.
DeltaT knob controls delay time with two distinct behaviors: in the first 25% of its range, time adjustment functions as a micro-timed continuous shift, allowing the delay to function as a resonator, producing rich tonal textures.
Beyond this range, the knob locks into a BPM-synced grid, ensuring precise rhythmic subdivisions, including:
1/32, 1/16T, 1/16, 1/8T, 1/8, 1/4T, 1/4, and 1/2 notes.
To further sculpt the spatial and rhythmic complexity, the Regen knob controls feedback intensity, with an internal function allowing for infinite regeneration without system overload.
Additionally, Delay Shift introduces a percentile offset between the left and right channels, unlocking possibilities for polyrhythmic textures, expanded stereo imaging.
Built-in Reverb
Complementing the delay network, the built-in parallel reverb (diffuse knob) is designed as a one-knob solution that smoothly transitions from subtle, intimate reflections to vast, enveloping ambiance.
A diffusion control automatically adjusts the density of reflections and functions as a natural acoustic enhancer or a synthetic atmospheric effect.
In its first half, it behaves like a tight to medium room reverb, perfect for adding clarity and presence to percussive elements, resonant leads, and evolving pads.
At its most extreme, the reverb creates dense, cloud-like textures that blur the boundaries between rhythm and space, producing dreamlike, ethereal environments.
Looper: Real-Time Layering & Manipulation
At the core of Uranograph's performance capabilities lies its double-reel tape looper, an integrated system designed for real-time sound capture and layering. Inspired by Frippertronics-style looping, this system enables continuous overdubbing, fostering an organic, evolving composition process.The looper captures the post-effects mix and sends it in parallel to two independent tape reels, which continuously record.
Both reels share the same time-division settings, selectable in clock counts: 1, 2, 4, 8, 12, or 16 beats.A common separate input and output volumes control the recording level.Two activator buttons determine which reel is actively recording—allowing for independent recording, simultaneous recording on both reels, or switching between them.Each reel features an erase head fader, which adjusts how much of the recorded material is preserved:At zero, recordings remain indefinitely, allowing infinite layering.At maximum, the reel continuously erases itself, functioning like a transient looping buffer.
Whether crafting intricate polyrhythmic structures or immersive, cinematic soundscapes, the tape looper encourages spontaneous experimentation and deep musical expression. Seamlessly integrated with Uranograph's synthesis engine, it serves as a powerful tool for both structured performance and free-form sound exploration, making it essential for dynamic composition and live improvisation.Save & Recall: Effortless Preset Management
Uranograph features a powerful save and recall system, allowing you to store and instantly retrieve all knob and fader positions, keyboard layouts, and parameter assignments for later use.
With eight banks of 12 programs, you can access 96 presets in total, ensuring extensive flexibility for live performance and studio work.
Metronome for Live Performance & Looping
A built-in metronome is routed exclusively to the headphone output to support live performances and looping workflows. This ensures discreet tempo guidance without affecting the main mix.
This feature is handy for looping, tempo synchronization, and structured live performances, helping musicians stay locked to a rhythm without external cues.
