Doepfer A-173-1/2 – Eurorack Micro Keyboard Module

The Doepfer A-173-1/2 is a two-part module:

• A-173-1: A button panel with twelve durable tactile buttons (one per chromatic note)

• A-173-2: A control unit that converts button presses into CV and gate signals

You can use it to:

• Manually trigger notes

• Shift octaves up or down

• Play chromatically in real time

• Send CV/gate to oscillators, filters, envelopes, etc.

It’s a compact, playable interface for hands-on control, ideal for live performance and experimental modular setups.
