Add Thickness and Width to Anything

Add Thickness and Width to Anything

Just like the vintage hardware, use Studio D Chorus' push buttons in any combination for a colorful palette of subtle thickening. Engage all four buttons at once and you get a beautiful chewy modulation texture that works on any instrument.

Create Movement and Interest

Create Movement and Interest

Make simple guitar/vocal arrangements sound deeper and more interesting, or quickly gel groups of strings and vocals —  without compression, EQ, or reverb. For floating guitar textures and synth pads, the Studio D Chorus plug‑in simply can’t be beat.

the best you can do to your tracks, try the demo !

took me some time to decide to get this one, got the demo, checked it out -and we’ll, won’t miss it anymore. So bought it. It makes an even phantistc sounding dry synth come alive, the effect is widen the signal and also to make bass sounds more compatible with small speaker systems. Same with other signals. Very well done clone off the original I‘ve used on several productions back in the 80th. Great job UA !

Time saver

As with other UAD plugins I've used, this one gives instant results with minimum efforts. It also sounds good on almost everything I've tried it on, from piano to drums, from background vocals to strings group. It widens the sound in a very pleasant way and lets other tracks come through without conflicting or overlapping. Sometimes you may find that you don't need to use any other plugin on top of Studio D Chorus (including compression, EQ etc.) because your track already sounds great.

Favorite Chorus

After owning several “Chorus” plugins, I believe I’ve finally found The ONE. It adds a non-digital, analog character to my sounds and vocals.

Studio D-licious

This fills my bucket. Everything old is new again, and it sounds as fresh as the day it came out 40+ years ago.

Amazingly useful

The only invisible chorus I know. Fits easily into any mix, removes sharpness und broadens the stereo image in elegant ways. Only downer is the original designfidelity - I would have liked a dry/wet-control. Still, all in all an underrated gem.

The best modulation plugin

Use this on setting 3 for vocals on a bus, and by far my favourite choice of modulation!

Has UAD removed the Roland Dimension D plugin for this?

I demoed the Roland Dimension D a month or so ago and absolutely loved it. Super authentic to its vintage gear version. After my demo expired, I clicked the shopping cart to buy it, but was redirected to this. Not only that, I can't find Dimension D anywhere on the site. The Dimension D plugin hasn't been removed from the current collection, but there seems to be no way to purchase it without be directed here. I fully agree with another reviewer — this is obviously not the same. If this is actually replacing the Roland plugin, I will be very upset. UAD: Please address this issue.

Great definition, not many options

Could have been made with different modulation options but still solid

Gives Dimension!

Not sure what's not to love with the SD chorus. It widens everything. I know there's all sorts of methods to do this now days, but this is a beautiful time tested sound. Plugin nails the sounds.

Killer Plugin for Producing Rock and Metal

This is a magical plugin when I am producing rock and metal songs. It adds depth and creativity to my rock and metal productions by adding subtle shifts of the vocal, guitar or keyboard tone and width. Love that it's dirt cheap too!
