KOMA Elektronik - Sensei Sensor Module

Ever wanted your patch to react to a passing shadow, the rhythm of a flickering light, or your own touch? Sensei acts as a bridge between your Eurorack system and the physical world, translating environmental phenomena into controllable voltage. It invites you to let light, movement, and touch become active participants in your synthesis.

The module is divided into two distinct halves. The upper section is designed for continuous analog sensors. It allows you to take a varying signal, adjust its intensity up to a 2x boost, and shift its position with an offset control. An inverted output is also available, which is great if you need opposing modulations from a single source.

The lower half handles events from switch-style sensors, turning a simple trigger into a gate or a ramp output. The length of this output can be set manually or modulated via CV, making it great for interactive rhythmic duties. Because the output is re-triggerable, you can create more complex, stuttering envelopes that respond directly to sensor activity.

Sensei's utility doesn't stop at sensors. You can use its features to process any signal in your rack. The analog section becomes a handy CV manipulator, while the switch section can be used as a standalone, re-triggerable envelope generator. It’s compatible not just with KOMA’s own sensor lineup but also with common Arduino-type sensors, opening up a wide field for experimentation. Your modular just grew a few more senses!

Features:

• Dual sensor interface for Eurorack (Analog & Switch inputs)
• Offset and intensity controls for analog signals
• Inverted and non-inverted outputs (for the analog section) up to ±10V
• Switch section with CV-controllable length and polarity option
• Gate and ramp outputs (for the switch section)(0–5V)
• Functions as CV processor, envelope generator, or voltage source
• Works with KOMA Field Kit sensors and standard Arduino-type sensors (3-pin)
