For my camera, I selected “high”, but you might see a different set of options depending on your camera. In the window that comes up next select your camera (Device) and resolution (Preset). I’m going to call my Logitech C920 “C920”. Select Create new and call it something clever like “webcam”. With your newly created Scene selected, click the + in the Sources panel. Have I mentioned that I am a creative professional? Add your camera First, we’ll need to create a Scene by clicking the + in the Scene’s panel in the bottom left. Create a “Scene” in OBS StudioĬreate a Scene that combines your camera and VMPK. To use it for our live presentation, we can put other windows on top of it, but we can’t minimize or close it. We’re done messing with VMPK for now, but leave it open in the background. That will ensure that VMPK will accept any incoming MIDI signal from any connected MIDI device. If you don’t see anything change when you play the keyboard, open Edit > MIDI Setup and make sure you have checked Enable MIDI Input and MIDI Omni Mode. Test your keyboard to make sure it’s lighting up the keys you expect in VMPK. You may need to adjust the “Base Octave” in VMPK to get the register you expect. I have mine set to be 61 keys so they don’t get too small to see over Zoom. I like to stick with plain ol’ blue, but you can do whatever you like, including a multicolor setup. In preferences ( vmpk > Preferences) you can change the number of keys and the colors that it uses. It’s not beautiful, but it’s very functional. VMPK should work pretty much right out of the box. You should only have to go through all these steps the first time. This will take a little bit of setup the first time, but everything will be saved automatically. Finally, in Zoom, we’ll select that fake camera, instead of the one plugged into the computer. Then, we’re going to send that stream to Zoom by creating a virtual 3 camera. We’re going to use OBS Studio to combine the camera feed and the VMPK window into a single video stream. After you’ve installed the virtual camera plugin, you may have to restart Zoom or OBS Studio once or twice to make sure they’re seeing the new virtual camera. I’ll give you a minute to download and install all that stuff. Virtual camera is now built in on Windows and Mac. If you’re following along on Windows, you’ll need this version of the OBS virtual camera plugin instead. I’m going to describe this setup for the Mac, but it should work more-or-less the same way on Windows. Virtual MIDI Piano Keyboard (VMPK, free and open source).OBS (macOS) Virtual Camera plugin (free and open source) No longer required as of OBS Studio 26.1.Webcam (mine: Logitech C920 2, but the built-in one is fine).USB MIDI keyboard (mine: Yamaha P-115, for the price and size, I like this one.).Mac (Windows will also work, but I’m not set up to demo it.).Now that we have our measurable learning outcome, let’s take a look at the next part of the syllabus. Live video from my webcam, plus an interactive animated keyboard that responds to my connected MIDI keyboard.
