You get an ADSR envelope generator in Eurorack format. Each time a gate signal comes in, it makes an adjustable control signal, and you shape it with attack, decay, sustain and release. It suits you if you want to move a VCO, VCF or VCA over time, since the envelope comes out in normal and inverted form.
Pros
- Generates a control envelope that can modulate VCO, VCF and VCA modules
- Outputs the envelope in both normal and inverted S-form
- Four parameters, attack, decay, sustain and release, can be set independently
Cons
- Free-running ADSR-LFO mode requires the separate A-167 comparator module
-
The Maths Black & Gold is a powerhouse for sound design. Its discrete analog circuitry creates a unique sonic texture, and the routing possibilities are nearly endless. It’s perfect for experimental electronic musicians, sound designers, and anyone wanting a modular core for complex modulation.
Pros
- Robust black anodized aluminum faceplate feels incredibly solid and premium.
- The gold knobs offer excellent tactile feedback and a luxurious aesthetic.
- Extremely versatile – capable of complex modulation sequences and dynamic envelopes.
Cons
- Can be overwhelming for beginners due to its many routing options.
- Relatively high power draw necessitates a robust power supply.

You get one module that can act as an envelope, LFO, oscillator, or slew limiter, so it suits anyone building a Eurorack setup who wants flexible control signals. It can turn Gate and Clock signals into analog signals and combine up to 4 control signals, which helps when you want more complex modulation. Because it is a Eurorack module, you will need a compatible case and power to use it.
Pros
- Generates linear, logarithmic, or exponential triggered or continuous functions
- Works as an envelope, LFO, oscillator, and slew limiter in one module
- Converts digital Gate and Clock information into analog signals
Cons
- Needs a Eurorack case and power supply, as it is a 20 HP module

You get a voltage controlled ADSR envelope with a CV processor, so you can shape how a sound changes over time. The first half of the pots works in fine millisecond steps, and the second half reaches up to one minute, so you can handle both quick and slow changes. This one suits you if you build a modular rig and want precise control over your envelopes and the signal they send out.
Pros
- First half of the pots gives high-resolution settings in the millisecond range
- Second half of the pots adjusts the time range from 1 second to 1 minute
- Attack slope switch selects a logarithmic or exponential Attack characteristic
Cons
- Needs +12 V and -12 V power, drawing +34 mA and -18 mA

How to choose the best envelope modules
Attack Time
This isn't just about how fast a sound gets loud; it's about the character of that attack. A slow attack can give you a swelling, lush feel, while a snappy attack cuts through the mix instantly - crucial for basslines in a band. Too fast and it's harsh, too slow and it's muddy.
Decay Time
This is where a lot of the 'groove' lives. A short decay creates a percussive 'thwack,' while a long decay can create a sustained, ethereal pad. It's often the decay that really shapes the overall tone - a short decay can leave a sense of incompleteness.
Sustain Level
Think of sustain as the 'plateau' of your envelope. It dictates how long a sound holds its peak volume. Too low and it dies out too quickly; too high and it can sound static or lifeless. It's the control that balances the attack and release.
Release Time
This controls how long a sound lingers after the key or trigger is released. A short release is great for tight, percussive sounds, while a long release creates a trailing, decaying effect. A poorly set release can cause clicks or pops, especially with oscillators.
Curve/Shape Control
Beyond the basic ADSR, look for modules with curve or shape controls. These allow you to tweak the envelope's response - exponential, logarithmic, or even custom shapes - which can dramatically alter the feel and character of your sound, giving you more expressive control.
Buying guide
Let's talk envelopes. They're the heartbeat of your modular patch, dictating how sounds evolve and breathe. A weak envelope can make a patch sound lifeless, while a dialed-in one can give you everything from screaming leads to subtle, evolving textures. Finding the right one isn't just about ADSR - it's about finding the feel that works for your music, whether you're building soundscapes in the studio or cutting through a loud band rehearsal.
Don't chase the cheapest option - envelope modules are often the unsung heroes of a patch, and corners are frequently cut. Look for modules with a good range of timings and, ideally, some kind of curve shaping. A basic ADSR is fine to start, but that extra control can be the difference between a usable patch and something truly inspiring.
Paying a little more for a module with a robust build and a consistent response is almost always worth it.

Questions
What's the difference between an ADSR and an AR envelope?
ADSR (Attack, Decay, Sustain, Release) offers more control, letting you shape the entire envelope. AR (Attack, Release) is simpler, great for percussive sounds where you want a quick attack and a defined release, but lacks the sustain control.
Can I use an envelope module to control filter cutoff?
Absolutely! That's a classic technique. It's a major part of creating evolving sounds. Just be mindful of how the envelope's shape affects the filter's timbre - too aggressive and it'll sound harsh, too gentle and it'll be bland.
My envelope is causing clicks or pops. What's happening?
Usually a release time that's too short or a poorly-matched oscillator. Try increasing the release time or adjusting the oscillator's gate behavior. Sometimes a slight offset in the envelope's trigger can help too.
I want to create a slowly rising drone. Which envelope settings should I use?
A very slow attack, a long decay, a low sustain level (or none at all), and a long release. Experiment with curve shaping to soften the attack and make it even more gradual. The goal is a seamless transition.
Do I really need multiple envelope modules?
Not initially, but as you build more complex patches, having different envelopes with unique characteristics - fast, slow, curved - can be invaluable. Think of it like having different types of compressors - each suited to a different task.
