How to choose the best mixer, attenuator modules
Gain Staging & Headroom
This isn't just about volume. A good mixer module provides clean gain, letting you push signals without nasty digital distortion or excessive noise. Cheap modules often introduce hiss or compress the signal prematurely - a real killer for subtle textures.
Attenuation Range & Accuracy
How precisely can you dial back a signal? Some attenuators have coarse steps that make fine-tuning impossible. Look for a wide range (ideally 0-100%) and a smooth, predictable taper - especially important for modulation.
Noise Floor
Modular synths are inherently noisy, but a bad mixer module can amplify that. Listen carefully for hiss or hum, especially when attenuating signals significantly. It's a dealbreaker for quiet, ambient patches.
Routing Flexibility
Do you need pre/post fader options? Multiple inputs? Aux sends? Think about how you'll integrate the mixer into your patch - a basic stereo bus isn't always enough.
EQ & Filtering
Some mixer modules offer basic EQ or filtering - a huge bonus for shaping your overall sound or cleaning up muddiness. It's not a substitute for dedicated filters, but it can be a surprisingly useful tool for subtle tonal adjustments.
Buying guide
Okay, so you're diving into modular? Smart move. But a pile of oscillators and filters sounds like chaos without a good mixer and attenuator module. Seriously, these aren't just 'utility' - they're the glue that makes your patches sing, the volume knobs that let you actually hear the subtle nuances, and the crucial control points that keep things from getting completely out of hand. Let's break down what you need to know.
Don't skimp on the mixer - it's the foundation. Entry-level modules can be tempting, but the noise and limited functionality will quickly frustrate you. Paying a bit more for a module with good headroom, accurate attenuation, and flexible routing is an investment in your sanity.
Watch out for modules that claim 'infinite' routing options - those often translate to a convoluted patching system that's more hassle than it's worth.

Questions
What's the difference between an attenuator and a mixer?
An attenuator simply reduces a signal's level. A mixer combines multiple signals and provides individual level controls for each. Most mixers include attenuators, but not all attenuators are part of a mixer.
Do I really need a mixer module if I can just use multiple attenuators?
Technically, yes, but it's a pain. Managing multiple individual attenuators becomes unwieldy quickly, especially when you're trying to create complex evolving textures. A mixer module streamlines the process and gives you a centralized control point.
What does 'pre-fader' and 'post-fader' mean?
Pre-fader signals are tapped before the fader, so they're unaffected by the fader's position. Post-fader signals are affected by the fader. Pre-fader is great for modulation sources; post-fader is for the main output level.
My mixer module is introducing a lot of noise. What can I do?
First, check your power supply. A noisy power supply is the most common culprit. Then, re-examine your patch - a poorly shielded cable or a faulty module can also introduce noise. Finally, try attenuating signals less aggressively - extreme attenuation often amplifies noise.
Can I use a mixer module for effects sends?
Absolutely! Many modular users dedicate a mixer channel to sending signals to effects units. It allows for precise control over the send level and can be easily modulated for dynamic effects.
