Expert Sleepers IVO: Characterful Analog Filtering
The Expert Sleepers IVO is a 100% analog, resonant low-pass VCF (Voltage Controlled Filter) built around discrete transistor OTAs for a warm and musical response. A standout feature of the IVO is its switchable slope: users can toggle between a 2-pole (12dB/octave) response for classic, biting filter sweeps, or a 3-pole (18dB/octave) response for a smoother, rounder character. In 2-pole mode, the module is capable of self-oscillation, allowing it to double as a sine-wave oscillator. With two audio inputs, the IVO also functions as a convenient mixer for blending multiple sound sources directly at the filter stage.
Key Features:
-
Switchable Filter Slope: Easily switch between 12dB (2-pole) and 18dB (3-pole) low-pass modes.
-
Comprehensive CV Control: Voltage control over both the cutoff frequency and the feedback (resonance).
-
Self-Oscillation: Capable of generating a pure sine wave in 2-pole mode when feedback is cranked.
-
Onboard Mixing: Dual audio inputs allow for signal blending, with one input featuring a dedicated attenuator.
-
Signature Illuminated Jacks: Features LED-ringed sockets that provide real-time visual monitoring of signal levels.
