As Usine is a “special” (and sometime unusual) host so the VST version is not a “normal” VST plug-in…

It is not designed to be simple VST plug-in where you can load a single patch, but looks like the normal Stand Alone version. So patches and Workspaces are fully compatibles. Usine as Easine VST are designed to add a real “Live” features in your favorite host.

Better than a long an boring discussion about it, lets take a look of a simple example of Easine (choosen for his multi in/out features) in the host called Reaper®. Of course you can use any 2.4 VST host compatible like Cubase®, Samplitude®, Sonar®, Live®, etc. (sorry if we forgot your favorite one…).

We suppose that we have a small project with 3 tracks and we want to apply 3 different effects (one per track) with Easine.

Now, just add Easine VST on track 4.

In Easine add 3 effects from the library and use 3 different audio ins this way:

Now, we are going to add receives for this track 4, choose add receive from all tracks :

Now be careful to choose the good inputs in Easine : 1/2 , 3/4 and 5/6

Now you can see the 3 tracks correctly routed to their respective effects in Easine :

If you want to automate a particular control of Easine from your host, you have to choose which VST parameter has to be assigned to the control. In Easine/Usine you can assign up to 128 VST parameters.

Now imagine we want to create a curve in the Reaper track to control a parameter in the Easine patch.

Do a right click on a parameter and choose VST parameter :

Choose VST parameter	select param 0	next time you’ll open the window you’ll see the correct name

Now you can see and use your curve in your track:

To easily display or hide the Usine main window, you can assign the show button to a VST parameter and make a Midi Learn on it.
