when i open the logic pro x after i installed the sylenth1 its showing a message that says " failed to load audio unit sylenth1 , please contact the manufacturer for an updated version or further assistance .
i really aprriceate this if someone could help me cause i am a new mac user bought it before 2 weeks

 

I had the same issue. I reinstalled 32 Lives then [ Logic Pro X -> Preferences -> Audio Units Manager ] enabling/disabling Sylenth1. Then it worked. I hope it works for you too.

 

Sylenth is 32 bit and Logic Pro X only accepts 64 bit plugins. Get 32 Lives. http://www.soundradix.com/products/32-lives

 

Logic is 64-bit only and Sylenth is 32-bit only. You'll have to use a "bridge" application which will allow you to load the 32-bit Sylenth into 64-bit Logic. A popular one is 32 Lives. Bridges like 32 Lives do work, but it's not perfect.

Instead of updating Sylenth, Lennar is offering a package deal of Sylenth + 32 Lives. It's ridiculous. Consider dumping Sylenth, as I suspect lots of people have done. I don't miss it at all.

Edit: Several replies with the same info happened while I was typing mine. Oops.

 

thats the most ridiculous thing I've ever heard!!!!!... instead of implement 64-bit version they just offer 32-Lives??... they must be low on serious amounts of cash or credit.

 

On my Mac, this error "failed to load audio unit" appears only for 64-bit plugins or the ones ressurected by 32 Lives - so I assumed you already have the 32 Lives on your system. 32-bit plugins, Logic Pro X is not even trying to load them yet no reason to generate such an error message.

 

Or on the other hand, may be Apple's policy that eventually forces the important companies to code 64-bit version of their plugins. And we all win on the long term

Code:

Or Apple could stop being so gay and offer BOTH 32Bit and 64Bit support...just like every other DAW manufacturer! 

 

From Lennar Digital:

Sylenth1 on Mac OSX 64bit
13 November 2013

"Recently we receive a lot of questions about how to run Sylenth1 in 64bit hosts on Apple OSX, such as the new Logic X and Ableton Live 9. We are still working on a 64bit OSX version of Sylenth1 (the 64bit Windows version is already available) and we're hoping to get it done in the second half of 2014.

If you need to use Sylenth1 in Logic X (or any other 64bit AU host) on short terms, we recommend using the 32 Lives bitbridge.

For Ableton Live or Cubase (or any other 64bit VST host) you can use jBridgeM instead.

(You can follow us on Facebook to stay up to date with the latest news about the 64bit version for OSX)"

 

There a very simple + painless SOLUTION:
Install LOGIC 9 and you'll have Sylenth & peace of mind!
