Open Stage Control VS Soundplant

Run Open Stage Control on the computer as well. Create a basic interface with buttons for each of the products (you can do a lot of customisation in OSC, including adding images and all sorts), for each button set the OSC address to trigger the button in companion that corresponds to the video you want to play. Launch the server, and on the tablet connect to the server through a web client. Source: 11 months ago

First thought that popped into my head was to write a custom module in Open Stage Control that watched for that MIDI value and issued the commands you want. Source: about 1 year ago

There's also Open Stage Control which looks to be pretty similar. That would let you open it as a web server on your computer and connect to it over WiFi from your phone browser. Upside is that it's free (as in price), but would take some setting up and probably a bit of know-how as far as computer networking goes. Source: almost 2 years ago
