Metamyther’s Prophet 12 Delay Hack: Reverb Like a Roo in a Rainstorm

Metamyther kicks things off by promising to unlock a secret dimension inside the Dave Smith Instruments Prophet 12, and mate, he’s not mucking about. Instead of reaching for the usual plugins or outboard gear, he dives straight into the synth’s four independent delay lines, setting the stage for some serious sonic mischief. The Prophet 12 isn’t just a pretty face—it’s got some hidden grunt under the hood, and Metamyther’s out to prove it.

After clearing out the old patch and tweaking the amp release (so we’re not fooled by lingering tails), he cranks up the drive and sets those delays to work. The numbers on the delay times might not make much sense unless you’ve got the manual memorised, but who cares? It’s all about using your ears and letting the machine run wild. The initial sound is still pure delay, but you can feel the reverb magic brewing, like a storm rolling in over the Nullarbor.

Here’s where things get spicy. By nudging up the feedback, Metamyther starts to coax the delays into a reverb-like wash—though it’s easy to go overboard and drown the whole thing, so a bit of restraint is key. He then dives into the delay filter, slapping a low pass on all four lines to smooth out the top end and keep things lush rather than harsh. Panning the delays across the stereo field gives the sound a sense of space that’s wider than a footy field.

But the real curveball comes with the mysterious feedback mode—high versus low. Even Metamyther admits he’s not sure what’s going on under the bonnet here, and invites viewers to chime in if they’ve cracked the code. It’s a classic case of synth exploration: sometimes you’ve just got to twist the knobs and see what chaos unfolds. The result? A reverb that’s as unique as a backyard BBQ gone off the rails.

One of the biggest flexes in this video is how Metamyther manages to whip up massive, cinematic reverbs using nothing but the Prophet 12 itself. No external effects, no plugins, just pure synth wizardry. By assigning each LFO to a different delay line and modulating their times, he conjures up a chorusy, swirling space that sounds like it was plucked straight from a sci-fi soundtrack.

The Prophet 12’s character parameters get a workout too, adding extra grit and personality to the reverb. It’s a reminder that sometimes the best sounds come from pushing your gear in directions the manual never intended. If you want to hear just how wild and immersive these atmospheres get, you’ll have to watch the video—words alone can’t do justice to the sonic mayhem unleashed here.

Metamyther wraps up by tossing the ball back to the viewers, asking for their favourite Prophet 12 tricks and effects hacks. It’s a proper call to arms for synth heads everywhere—don’t just watch, get your hands dirty and see what kind of sonic storms you can whip up. Whether you’re a Prophet 12 veteran or just delay-curious, there’s plenty of inspiration here to keep you noodling for hours.
