After running recent update i see two versions (AU and VST) of EZD / SD plugins in Studio One

[tooner10]

i’m on a macos sierra running studio one pro 3.5+

i used to have only one instance each of EZD2 and SD in my S1 file browser instruments section. after recently updating EZD2, i now have two versions (one is AU and the other VST) of each in the same pane. what is the difference and when should i use one vs the other? which one should i be inserting on my S1 tracks? can i remove the one i won’t be using?

thx

Hi,

the update installer installs all flavours of the plugin unless you tell it not to (Customise), which on Mac is VST, AU and AAX.
It does not tax your system to have them all installed, since the plugin files are small.
If you uninstall or delete a plugin file, make sure you do not remove the VST plugin, since it is used by the Standalone app.

thx. what’s the difference between the different flavors? i always thought VST was the gold standard so why would i use one of the other ones? so can i just manually remove the other AU plugins from the directory and they won’t show up in S1 any more (no uninstall procedure required)?

VST is a platform independent standard developed by Steinberg.
AU is developed by Apple and only available on Mac OS.
You can manually remove the AU Components from ‘{Mac HD}/Library/Audio/Plug-Ins/Components/’, should you wish to, but there is no harm leaving them where they are and ignoring them in Studio One.
AU plugins are used by e.g. Logic and Garageband so if you delete them, they will not be available to hosts that use only AU plugins, unlike e.g. Studio One or Ableton Live that can use both.

ok gotcha thx! so would the AU plugins actually work in S1 or cause it to crash (meaning it only supports VST)? if they don’t work in S1, presonus should remove the AU and only show the VST. for me it’s just a clutter thing not having all 4 displayed to me (2 EZD and 2 SD) every time i have to choose them b/c the VST / AU signature is very tiny on the intefface widget so it’s hard to make out which one i’m dragging. BUT i would prefer to have them installed in the event i do want to switch over to GB to bring in things done on my iphone on iOS GB.

I think you can disable AU support – Preferences -> Advanced -> Services.

yeah you can do that. thx! i guess it doesn’t matter which one you use. i assumed one plugin flavor might be better or more efficient on a given platform otherwise why would they write two specs. i looked online and it appears that some AU plugins use a third party product (symbiosis?) to simply wrap the VST plugin which would seem to make the AU plugin more inefficient (an extra layer) vs rewriting the plugin to the new spec.
