It’s one more way your Eurorack modular is starting to look like a total replacement for your computer: stereo convolution reverb is next.

Sure, you’ve got convolution reverbs in your DAW, and maybe a favorite plug-in. But this hardware adds some twists – not just delivering realistic modeled reverberation to your modular rig, but bringing some hardware-specific functionality on the way. It’s the work of Tasty Chips, known for their granular hardware.

Quick refresher on convolution reverbs – the idea is, a sound measurement of the space lets you create a fairly accurate model of how sound will reflect. You record an impulse (some broad-spectrum transient or sweeping frequency, so you capture a full frequency range), and the resulting recording in time can then be applied to any source you choose. So, why would you want this in modular?

You can record impulse responses right on the device. Fire up your starter pistols (okay, more likely sine wave sweep), and record impulses directly. I imagine some people might just tote a portable modular rig into a church in the town where you’ve got a gig. Sure, you could do that with a recorder, too, but – this is at least fun. run

Alternatively, you can capture synth impulses from your modular, and then run those little synth-y bits through your saved impulses. I’ve always loved this for sound design, even outside the “what does my local parking garage sound like as a reverb.” (Apple’s pro apps team must like it, too, as you will find a bunch of these sorts of impulses in Space Designer in Logic these days.)

You can crossfade between convolution files.

There are tons of hardware controls. Also some nice thought into options like pre-delay and position.

You get CV control. Here’s the modular part – you can use CV to control position, crossfade, and stereo width. Convolution reverbs are normally a set-it-and-forget-it affair, so I’m curious how this works in practice, but it does help make the case for hardware.

The excellent Synth Anatomy get the scoop on this and have some of their own take:
