How to choose the best effect modules
Sound Quality
This is obvious, but 'good' is subjective. Are we talking about a lush, diffused reverb tail, or a brittle, digital shimmer? Does the distortion add warmth and sustain, or just harshness? Listen critically and think about the tone you're after.
CPU/Power Consumption
Modular systems are already power-hungry. A module that demands a ton of juice or eats up precious CPU cycles can cripple your setup. Especially important for Eurorack users - headroom is a precious commodity.
Modulation Options
Can you modulate the effect's parameters? A static reverb is fine, but a reverb that breathes with your LFOs? That's where things get interesting. Look for CV inputs and flexible routing options.
Hands-on Control
Some modules are designed for deep, knob-twiddling exploration, while others are more patch-centric. Consider your workflow and how much tactile control you need for live performance or quick adjustments during recording.
Size/Format
Eurorack modules are tiny, but they add up fast. 5U of modules gets heavy quickly. Other formats like Ableton or skiff-friendly formats can be limiting depending on your setup. Consider how the module fits your physical space and workflow.
Buying guide
So, you're diving into modular synths - awesome. Don't get so caught up in oscillators and filters that you forget the glue that holds it all together: effects. A pristine, sterile patch sounds like a demo; a well-affected patch breathes and has character. We're talking reverb, delay, distortion, modulation - the stuff that takes your sounds from 'functional' to 'inspiring'.
Don't chase the hype. A cheap reverb module might sound okay for basic ambience, but it'll likely lack the depth and detail of something more refined. Distortion modules often cut corners on the filtering, resulting in a muddy, unpleasant mess.
Paying more often gets you better components, more nuanced sound, and a more robust build - things that matter when you're gigging or recording.

Questions
What's the difference between a digital and analog reverb module?
Analog reverbs tend to have a warmer, more organic character, but can be limited in their features. Digital reverbs offer more flexibility and longer decay times, but can sometimes sound sterile if not implemented well. It's a tonal preference, really.
How much power should I budget for effect modules?
It depends, but assume each module will draw at least 20mA. Factor in headroom for transient spikes - things can draw significantly more momentarily. Overestimate rather than underestimate - a brownout mid-gig is no fun.
Are there any good budget-friendly distortion modules?
Sure, but be realistic. Expect some compromises - they might lack the nuanced harmonic complexity of higher-end options. Look for modules with simple, well-implemented circuits; avoid anything that sounds overly harsh or fizzy.
Can I use VST effects with my modular synth?
Absolutely! Many modular systems can send audio to a computer and process it with VST plugins. It's a great way to expand your sonic palette, but introduces latency, which can be an issue for live performance.
What's the best way to use modulation with effects?
Experiment! Try modulating reverb decay time for a pulsing ambience, or using an LFO to subtly shift the cutoff frequency of a distortion. Small changes can have a big impact on the overall feel of your patch.
