Doepfer A-138d Crossfader / FX Insert

The A-138d is a clever dual-function module combining a voltage-controlled crossfader and an external FX insert. The crossfader allows you to morph between two audio or CV signals, while the FX insert lets you incorporate pedals, rack FX, or other external devices into your Eurorack setup.

Both sections can be used independently or linked together. The FX section features a wet/dry mix that can be modulated with CV, making it perfect for dynamic processing or live control.

Key Features:

• Voltage-controlled crossfader for audio/CV

• External FX insert with CV-controllable wet/dry mix

• Sections usable independently or linked

• Great for routing, morphing, and external integration

• 8 HP wide
