Hey David, sure! Let me explain how I did it.
On Mac the interface is relatively accessible with VoiceOver, but I imagine you could do the same on Windows with a bit of visual help from someone. You only need to do this setup once.
First, open the SGX plugin in Reaper. A screen will pop up asking you to locate or download the samples—have the person helping you click “Download.” It’s about 4GB; on my Mac with fiber internet it took around 5 minutes, but of course that depends on your connection.
Once the samples are downloaded, the plugin should produce sound automatically when you send MIDI from your controller.
If your plugin isn’t activated yet (which I assume is the case), ask your friend to click either “Try” or “Activate,” depending on what you see. In demo mode, the plugin works for about 20 minutes (if I remember right), then you have to close and reopen it. Internal preset saving is also disabled in demo mode, but you can still save your presets using Reaper’s preset menu.
Next, ask your helper to select a basic preset from each piano model. The main ones are: German Grand, Italian Grand, Japanese Grand, Small Japanese Grand, and Japanese Upright. The idea here is to select one preset from each model and save them as Reaper presets, so you can easily access them later. Once you’ve got those saved, you can load one and tweak it using Osara’s parameter list—most of the parameters seem to be exposed there.
Hope that helps, and enjoy the pianos! They don’t replace the Modern D, but I feel like they fill a different niche… they serve a very different purpose.David Lai
