Frequently Asked Questions

The delta control dynamically shifts the frequencies between the two filters, creating a swirling, animated effect that’s great for evolving textures.
The normalization is Doepfer's classic approach; while functional, it can take a little getting used to if you're unfamiliar with their design philosophy.
The Shimmer is far more versatile with a wider range of modes and modulation options, but the A-121d VE offers a more focused, vintage-inspired character at a more accessible price point.
