An Overview of our VST Test Lab

A little history for everyone. Our main goal with this project is to learn about the installation and usability of various VST’s running on a Wersi OAX instrument. For those that are not aware, OAX is the heart of the latest generation of Wersi instruments and is hosted on a Windows 10 O/S. If you are interested in learning more about OAX you can follow along over on our sister site.

We decided to setup up a small test lab that will allow us to install a VST on a Windows 10 environment before we try the same install on our Wersi Sonic. Why? It will give us a basic understanding of how that VST works and the various controllers that you can map to it without introducing the OAX layer of complexity.

Basically, we would like to see it working as the vendor intended. At the same time if we find it doesn’t work within the OAX environment, we can go back to our VM setup and try some things in support of debugging.

A little more info on the simple diagram below:

  • The “Main P/C”:
    • Basically where we sit and do everything. Has all the expected interfaces up and running – A display, keyboard and mouse. Normal P/C “stuff”.
  • The “VMWare Workstation” machine:
    • Our intent here is not to try to teach you about virtualization nor do we have any interest in debating all the various hypervisors that are on the market.
      • We are using VMWare. Enough said about that topic.
    • The VMWare host machine has a physical connection to our LAN and a Focusrite 6i6 Audio / MIDI interface┬áconnected via USB.
  • That brings us our next machine, which is a VM (virtual machine) and what we are calling our “VM Guest”:
    • Why did we do all of this?
    • Basically to take advantage of the “snapshot” function provided by VMWare.
      • Simple, fast and an elegant way to capture a “picture” of a machine before you change anything.
      • If something goes wrong you can go back to the snapshot, taken before the changes, and everything is exactly the way it was before you made the change.
        • The time to take a snapshot or restore to a previous snapshot – measured in seconds!

Comments on the overall concept are more than welcome. Stay tuned as we take the next step.
