The Novation Circuit Mono Station represents an innovative fusion of the original Circuit's acclaimed sequencing capabilities with the sonic prowess of the Bass Station II analog monosynth. This unique instrument combines a pad-grid controller, dual-oscillator sequencer, and comprehensive analog synthesis in a compact, performance-oriented package designed for both standalone use and modular integration.
The Circuit Mono Station builds upon the foundation of the original Circuit's intuitive 16-step sequencing system while introducing paraphonic capabilities through its dual-oscillator architecture. Unlike traditional monophonic synthesizers, the Mono Station can sequence both oscillators independently, creating harmonic textures, chords, and complex timbral variations that bridge the gap between monophonic and polyphonic synthesis.
The instrument features the complete Bass Station II sound engine with carefully considered enhancements, including a new distortion mode, expanded mixer section, and comprehensive modulation capabilities. The addition of CV, Gate, and Clock connectivity makes it an ideal centerpiece for hybrid setups, capable of interfacing seamlessly with modular synthesizers and other analog equipment.
The Circuit Mono Station's workflow centers around pattern-based composition, with 16 patterns available for the primary oscillator sequencer and 8 patterns each for the secondary oscillator and modulation sequencers. The instrument supports real-time and step sequencing, with extensive pattern manipulation features including variable length, speed, direction, and the new Mutate function for semi-random pattern variations.
