New in Soundtoys 5.4: Little Plate Gets Longer Decay, and We Tested It on Drone Beds

Little Plate has always been the restrained one in the Soundtoys family. Three knobs, a switch, no menus, no pages. You put it on, you turn Decay up, you’re done. So when Soundtoys pushed 5.4 with a longer decay range on Little Plate, my first thought was practical rather than excited: what does a plate actually do with all that extra tail, and does it stay musical?

I loaded it on drone beds to find out. Long, slow, evolving chords, the kind that sit under a track and breathe. That’s where a plate’s tail either turns into a beautiful smear or collapses into a metallic mess. Here’s what I found.

What Actually Changed in 5.4

Little Plate models the EMT 140 plate, that classic studio workhorse. Before 5.4 the Decay control topped out at a fairly polite length, enough for vocals, snares, guitars, a tasteful ambient send. The 5.4 update extends that decay range so the tail can run noticeably longer than before. Same three knobs, same EMT 140 lineage, but the ceiling on the tail has moved up.

That’s the whole story of the update, and honestly, that’s how Soundtoys tends to work. No new interface, no feature bloat. They extended a parameter and let you decide whether the sound holds up that far out.

For context, Little Plate usually runs around $129 as a one-time purchase, though Soundtoys has offered it free for limited stretches in the past, so it’s worth watching if you’re on the fence. The longer decay doesn’t change the character. It just gives you more room to stretch.

Why a Plate on Drone Beds at All

Most people reach for a big algorithmic hall or something like Valhalla Supermassive when they want endless atmosphere. Fair. Supermassive gives you those massive tails and warp effects for free, and it’s hard to beat. But a plate does a different job.

A plate has density. It fills space quickly without washing everything out into a smooth cloud. On a drone bed, that density is exactly what you want. The reverb clings to the harmonics instead of smoothing them into mush. You get a shimmer on top of a low pad rather than a fog around it.

Classic plates like the EMT 140 were bright, slightly metallic, and forward in the mix. Little Plate captures that. Where a hall pushes a sound back, a plate keeps it present while adding air. On a sustained chord that never resolves, present-and-air is the whole game.

Testing It: Settings That Worked

I ran Little Plate on a few different drone setups, all on sends so I could blend the dry signal underneath. A few things stood out once the decay went long.

Low-pass the send, always

The first thing that goes wrong with a long plate tail is low-end build-up. Push a full-range drone into a plate with the decay near the top and the bottom octave turns into a muddy rumble that eats your headroom. I put a gentle low-pass on the send, rolling off below roughly 200 Hz, and the tail cleaned up instantly. The plate kept its shimmer up top and stopped fighting the sub.

Lean on the low cut and modulation switches

Little Plate has a low cut and a modulation switch, and both earn their keep at long decays. The low cut does the same job as the send filter but from inside the plugin, which is handy when you want it self-contained. The modulation adds a slow drift to the tail. On a static drone, a touch of modulation keeps the reverb from sounding like a frozen sample, which is exactly the failure mode of a long tail on unchanging material.

Watch the predelay feel

The predelay on Little Plate is fixed rather than adjustable, so you can’t slide the reverb onset around freely. At short decays that’s invisible. At long decays it matters more, because the gap between the dry hit and the tail becomes part of the texture. On slow pads it’s fine, even lovely. On anything with a sharper transient, the fixed predelay can feel slightly off. Something like FabFilter Pro-R, with its surgical control over decay shape and frequency, would be the tool if you need per-band precision. But Pro-R runs around $199 and thinks in spectrums. Little Plate thinks in vibe. Different jobs.

Where the Long Decay Actually Shines

On a drone that holds a single chord for eight or sixteen bars, the extended decay lets the tail bloom into the gaps between notes. Play a slow arpeggio and let it ring: each note’s tail overlaps the next and you get a chord that builds itself out of single voices. That’s the sound I kept chasing, and the longer range makes it easier to reach.

It also works as a glue send. Route several sparse elements, a plucked note, a breathy pad, a distant bell, through one long plate and they start to share a space. That shared tail makes separate parts feel like one instrument.

And on lo-fi and tape-flavored material, a long plate tail sits beautifully against the wow and flutter of a tape emulation, or the crackle of something like iZotope Vinyl. The plate adds a clean shimmer on top, the tape sits underneath. Warmth plus air.

Where It Gets Annoying

Turn the decay all the way up on a busy passage and it gets cloudy fast. A plate isn’t a hall. It doesn’t have the same sense of distance, so a huge tail on dense material just piles up around the dry signal. On a drone bed that’s the point. On a full arrangement it’s a problem. I ended up treating the top of the decay range as a specialty setting for sparse, slow material, not a default.

The fixed predelay and three-knob layout are both a blessing and a limit. When I wanted to carve specific frequencies out of the tail, I had to reach for an external EQ. Little Plate won’t do that for you. It’s a fast, opinionated tool, and the 5.4 update doesn’t change that.

Does the Update Earn Its Place

Yes, if you make atmospheric music. A longer decay turns Little Plate from a nice vocal and snare plate into a genuine ambient texture tool, and it does it without adding a single control. That restraint is the whole appeal. For drone beds specifically, the extended range plus the modulation switch plus a low-pass on the send gives you a tail that blooms and breathes instead of smearing.

If you already own Little Plate, the update is a free reason to revisit it on your pads and drones rather than just your drums. If you don’t, weigh it against the free options first. Supermassive covers endless tails for nothing. But Supermassive and Little Plate aren’t competitors. One is a cloud, one is a shimmer. On the right drone bed, the plate does something the cloud can’t.
