The Spectralis 2 is the enhanced successor to Radikal Technologies' sophisticated hybrid synthesizer, establishing a new benchmark in electronic music production. Released as an evolution of the original Spectralis, this powerhouse instrument combines advanced DSP technology with true analog circuitry to deliver exceptional sonic capabilities. With expanded memory, an improved sequencing engine, and streamlined sound selection, the Spectralis 2 maintains the revered sound engine of its predecessor while introducing significant workflow and performance enhancements.

Overview

The Spectralis 2 retains the warm, rich sound character that made the original Spectralis renowned, while implementing a redesigned sequencer engine that enables continuous, real-time sequencing without interruption. This major improvement allows musicians to create and modify sequences on the fly during live performances without stopping playback—a feature highly valued in performance contexts.

At its core, the Spectralis 2 features a hybrid synthesis architecture that combines cutting-edge DSP technology with authentic analog circuitry. The oscillator section consists of four digital oscillators with continuously variable waveshapes enhanced by time linearity modulation, FM, PM, oscillator synchronization, and bit reduction capabilities. Each oscillator features independent pitch and volume envelopes for precise sound sculpting.

The analog filtering section showcases two meticulously designed true analog circuits: a self-resonating 4-pole lowpass filter and a versatile 2-pole multimode filter offering lowpass, highpass, bandpass, and notch outputs. These analog filters overcome the limitations of digital modeling approaches, providing organic timbral qualities and responsive sound manipulation.

A distinctive element of the Spectralis 2 is its fixed filterbank, consisting of eight bandpass filters plus additional lowpass and highpass filters. This sophisticated spectrum-slicing tool enables the selective modification of frequency bands, facilitating the creation of everything from realistic instrument emulations to experimental sonic textures. Unlike vintage modular systems, the Spectralis 2 filterbank offers sequencer-controlled level modulation and comprehensive parameter editing, including individual frequency band panning, Q and roll-off slope control, and filter stage spacing.

The sampling section delivers true multisampling capabilities with a 32 stereo voice polyphonic sound engine and powerful subtractive synthesis features. The high-speed USB2 interface allows quick transfer of samples from a computer, with an included conversion utility supporting WAV and SoundFont2 formats. For live performance reliability, the Spectralis 2 includes both onboard flash memory (expandable to 2GB) and an SD card slot for storing samples, songs, and sound presets.

The sequencing system represents a significant advancement, featuring a pattern-based approach with both real-time and step-by-step recording options, as well as grid-based drum programming. The step sequencer provides 32 independent parameter control lines with up to 192 steps each, enabling complex polyrhythmic patterns and tempo-dependent sound manipulations. During live performances, users can mute/unmute tracks, swap motifs on the fly, adjust mixing parameters, and transpose entire patterns by simply pressing keys on a connected keyboard.

The Spectralis 2's quick sound selection feature puts favorite sounds within immediate reach, streamlining workflow during intense creative sessions or live performances. The system is built around high-quality components, including Texas Instruments floating-point DSPs and Burr Brown digital-to-analog converters, ensuring pristine audio quality throughout the signal path.
