Instruo Modular CS-L Voltage Controlled Oscillator Eurorack Module

Expand Your Palate with the Instruo Modular CS-L Voltage Controlled Oscillator Eurorack Module

The Instruō Cš-L is a dual analogue oscillator optimized for generation of complex waveforms. It features two contrasting discrete circuit oscillators that are normalled to one another, offering a variety of simultaneous modulation routings. The resulting harmonic timbres sit far beyond the realms of traditional subtractive synthesis.

• Sawtooth core voltage controlled oscillator (Oscillator A – Top)
• Triangle core voltage controlled oscillator (Oscillator B – Bottom)
• 1V/octave, Coarse and Fine pitch controls per oscillator
• Frequency modulation input per oscillator, linear or exponential response, with attenuators
• LFO range switch for oscillator A
• Switchable link between 1V/octave inputs for parallel tracking
• Multiply output with three modulator behavior options
• CV over each wavefolder with attenuverters
• Symmetry offset control for each wavefolder with attenuverters
• CV controllable modulation bus (INDEX) with versatile definable internal routing

SPECIFICATIONS

• Waveforms: Sine, Triangle, Square/Sub, double pulse, wavefold final
• Width: 26HP
• Depth: 42 mm
• +12V: 200 mA, –12V: 80 mA
