This is such a wonderful synth, but cpu killer
  Resident 18.10.2008 510
and what makes it so special over other zillion of synths we got out there?
  Resident 9.10.2016 2 165
the code! simple as that.

It's a bit-perfect recreation of the amazing Virus synths that are in so many of the songs we all love. That's special.
  Resident 23.12.2009 2 1356
it's filters, analog effect, distortion, modfx, reverb and snappy envelopes
  Member 11.01.2020 66
Try out as many different synths as possible, get used to how they sound for a while and then come back to this. Once you have an idea of what to listen for it's blatantly obvious this thing is gold.
  Member 27.04.2022 127
This thing utterly rules so far.
And its barely out of the oven.

Imagine by the time it emulates everything.

hANDwASH what is the difference between 'DSP56300Emu 1.2.19 MacOS AU' and this 'DSP56300Emu1.2.19 MacOS AU_FX'?

the 2nd can be used as insert FX.

Thanks Articstorm

I wonder if the AU actually works in Logic yet?

Edit: Never mind. Still crashes Logic every time.
  Contributor 3.05.2011 595 3966
Maybe it is not signed? Maybe you can bypass check for signature? (i am no expert on mac, but it was reported working)

Here work well (Sierra / Logic 10.4.2)
 - ElMoreno plays LogicX on Mac - 
  Resident 23.12.2009 2 1356
works like a charm here, dequarantize it .
  Resident 27.10.2011 318
I'll give that a shot!

Edit: No go here on Mojave/Logic 10.5.1. Tried codesigning, deep signing, dequarantize. Crashes Logic every time. Guess this is just a no-go on my system? Weird... Most everything works on this rig.
  Resident 10.12.2008 5 750
Tried BatChmod and Restart?
 - ElMoreno plays LogicX on Mac - 
  Resident 27.10.2011 318
Good reminder! Nope... I'll try that. Thanks!

Edit: Nope. Crashes Logic validation every single time. Tried installing the .vst also, thinking maybe the system needed to see both. Simply will not work on my system. Bummer! I used to own a Virus-b. Would love access to those Access sounds again!
  Resident 10.12.2008 5 750
Try this in precise order, it worked for me with some plugins:
1 - BatChmod 1.6.3
2 - CodeSigner 0.9.3 (Deep)
3 - Now Open Plugins Manager in Logic, select the plug (> DSP56300Emu) and click on Validate. Repeat 2/3 times if Validate not work at first attempt.

  Resident 27.10.2011 318
Followed this to a T. Tried validating several times. Crashes immediately every time. I have NO clue why this won't work. Thank you SO much for all your help and suggestions ElMoreno. Maybe something unique on my system? I'm running Mojave and legit Logic 10.5.1 (haven't upgraded cause I don't wanna upgrade past Mojave on this Mac Pro trashcan).
  Resident 10.12.2008 5 750
All that remains is to make the last attempt by deleting the AU plugin Cashe: often it helps.

Go to ~/Library/Caches/AudioUnitCache/
- Manually delete the 'com.apple.audiounits.cache' file (to force a complete new plug-ins scan).
- Re-open Logic Pro X
- Reboot the computer (mandatory)


I guess so, but have you tried loading an older version of the plug?
At this point, try this as well...

De-quarantize in the terminal:

sudo xattr -cr /Library/Audio/Plug-Ins/VST3/DSP56300Emu.vst3
sudo xattr -cr /Library/Audio/Plug-Ins/VST3/DSP56300EmuFX.vst3
sudo xattr -cr /Library/Audio/Plug-Ins/Components/DSP56300Emu.component
sudo xattr -cr /Library/Audio/Plug-Ins/Components/DSP56300EmuFX.component
sudo xattr -cr /Library/Audio/Plug-Ins/VST/DSP56300Emu.vst   
sudo xattr -cr /Library/Audio/Plug-Ins/VST/DSP56300EmuFX.vst

see it is anytime the same command:

sudo xattr -cr<<<space>>><<<<path to the plugin>>>

you dont even need to type teh path, just open a terminal window,
sudo xattr
hit space
drag plugin to terminal window and it will addd the full path :)

I just saved the lines above in a text file, added the file extension extension .command and gave rights chmod +x to make it executable. so each time a new release comes out i just have to replace the old plugins and run that command.

I've tried this also but it just constantly crashes Studio One 5.5 on my MacBook Pro Mid 2010 Frankenstein machine. I call him Frankenstein because I've hack Big Sur onto it.
That's the only reason I can't use any version of Waves plugins. But it'll do until I buy a brand new MacBook Pro.

Amazing Virus B/C synths emulation! Thanks.
Hope the developers will implement the ROM switching feature (on-the-fly), via the droplist.
