Multi CTRL / Eurorack / PCB and Front Panel

Multi CTRL

The Multi CTRL Eurorack PCB and Front Panel Kit is a DIY control voltage utility module designed to control multiple parameters using a single knob. It generates a bipolar control voltage and distributes it across multiple outputs, making it ideal for coordinated modulation and macro-style control in Eurorack systems.

Key Features

• Eurorack PCB and front panel kit
• Single-knob controller for multiple destinations
• Generates bipolar CV from -5V to +5V
• Four CV outputs, each with:
  • Individual amount control
  • Inverter switch
• External CV input to combine with the generated control voltage
• Can function as a simple active multiple
• 10HP Eurorack format

Control & Modulation

Multi CTRL allows you to create a central control voltage using the main CTRL knob and send it to up to four destinations simultaneously. Each output can be independently scaled and inverted, enabling complex modulation relationships such as opposing movement, subtle offsets, or exaggerated responses.

An external CV source can be added to the internally generated CV, allowing the module to act as a modulation hub that blends manual control with dynamic modulation sources.

DIY Build & Front Panel

This DIY Eurorack CV control PCB and front panel kit is intended for intermediate builders. The front panel is made from durable PCB material and screen printed by hand, ensuring a cohesive aesthetic across Guru Gara Synth modules.
