Are You Sure You Need to Upgrade?
“OOOOOH WOWWW! Indentured Instruments announced a MK II of their Quad Rampulator. I better sell my MK I fast!” Hold on there, partner. Before you rush to hit the “sell” button, take a moment. Breathe. Let’s talk about that impulse. Are you sure this new version is actually worth upgrading to? Ask yourself: How are you using the original? Have you been happy with it? Does the new version actually solve a problem you’re facing, or is it just shiny and new? What’s the real cost, both financially and for your workflow, of making the upgrade? Most importantly, do you need it, or is it just a nice-to-have?
Upgrading isn’t always necessary. Plenty of people are selling awesome modules just because they’re out of fashion, not because they’re broken or obsolete. So why not take advantage of that? Several classic envelope generators are just as powerful and versatile as newer ones, but much cheaper.
Why Old Gear Still Kills
Would you give up an SH-101 for a SH-01A. Not a fucking chance in hell. There’s always something newer, shinier, and more advanced being released. But that doesn’t mean older modules aren’t still incredibly useful. Classic envelope generators, in particular, can provide just as much creative freedom as the latest models, and they often come at a fraction of the cost.
So before you go chasing the next big thing, consider the value of sticking with—or even seeking out—some of these older modules. They offer proven reliability, and sometimes creative features that newer gear sometimes lacks. Plus, you’ll save some serious cash in the process.
5 Amazing and Affordable Envelopes You Shouldn’t Ignore
Intellijel Quadra and Expander
The Intellijel Quadra was unseated by the Quadrax. I mean it has an X, so it must be better, right? It offers four envelope generators, in a compact space, yet incredibly roomy for your fingers. With the Expander, you get a ton of CV control putting it on par with the Tiptop Audio Buchla 281t in 4hp less. I challenge you to find envelopes that compete.
Personally, I keep coming back to the Quadra after flirting with newer gear, and every time I do, I’m reminded why it’s a mainstay in my setup. It’s not flashy, but it always delivers.

The 4ms PEG may not have the same buzz it once did, but it’s still excellent for rhythmic envelopes. It syncs to a clock, letting you divide or multiply it to create slower or faster repeating envelopes. With CV control over Div/Mult, Skew, and Curve, you get precise, dynamic envelope control.

Hexinverter’s Galilean Moons combines two envelopes with built-in VCAs. Originally designed to pair with the Jupiter Storm noise module, creating a complete dr10um synth. The envelopes can be switched between linear and exponential curves, giving you even more control over the feel and response of your sounds.
While its 18hp size might seem large by today’s standards, recreating its functionality in a smaller footprint would be difficult—and you’d lose the comfortable parameter spacing.

The Intellijel Dual ADSR is as classic as it gets—a simple, intuitive dual envelope generator modeled after the envelope controls found on classic Roland synths. With sliders for each stage (attack, decay, sustain, release), you have hands-on control, making it easy to shape sounds on the fly.
This module’s real strength lies in its simplicity. There’s nothing fancy about it, but that’s exactly what makes it so great for everyday use.

Pip Slope MK1 may be small, but it packs a punch. This tiny envelope generator is super straightforward but incredibly fast and effective. If you’re low on rack space, this is an excellent option that won’t crowd your case but will still add plenty of modulation flexibility.
Whether you’re building a portable system or just need a reliable, compact envelope generator, Pip Slope delivers in every way that matters.

So why bother with these older modules when there are so many new ones out there? Let’s break it down.
First, these modules are often significantly more affordable. They’ve stood the test of time and proven their worth in countless setups, yet they’re available on second-hand markets for way less than their original retail price. They’re reliable, they sound great, and they offer unique features that newer modules sometimes lack. Many of them are also easier to use, with simple, intuitive interfaces that allow you to shape your sound quickly and efficiently. And because they’ve been around for a while, they’re easy to find on platforms like Reverb.
