This is a simple VJ style app. It is used as an experiment to learn more about UWP in regards to real time media handling.

Note that the goal of this app was not to create a polished VJ app, but to learn some basics of Windows 10 UWP development. So assume that the code is probably not the best source of reference on how to implement things.

• 4 track, 8 step sequencer.
• Assign and trigger videos at each step.
• BPM control.
• Set opacity for each track to mix video output.
• Set playback speed for each track to match BPM.
• Full MIDI control.

Build and run with Visual Studio 2017. VS 2015 might work, too, but I didn't test it.

• Click / tap on a slot to load a video.
• Use activator under each slot to activate them.
• Adjust the opacity for the respective track.
• Hit the play button to start the sequencer.
• Activated slots with videos will be played in the player window.
• The Reset button (below the play button) will reset the step counter to 0.
• Tap the space bar on each beat to set the BPM.
• Press left / right to de- / increase the BPM count by 10.
• Press down / up to halve / double the BPM count.

• Fullscreen option for player window.
• More Fluent Design touches.
• Clearing tracks should stop and clear the respective player.
• The whole thing is slow and stutters / flickers. Maybe I'll fix that.
• Add an option de- / activate Stretch="UniformToFill" to the UI.
• Effects? See https://code.msdn.microsoft.com/windowsapps/media-extensions-sample-7b466096 and https://english.r2d2rigo.es/2016/03/10/creating-custom-video-effects-in-uwp-apps/
• Webcam support?

Technocoid was a side project of mine a couple of years ago (2002 or something like that). It was a simple VJ tool to experiment with realtime OpenGL based graphics, input (MIDI and some game controllers were supported), and UI. And of course to have a tool to do VJ gigs. I stopped developing it when I discovered Neon and later Neon v2.

Recently I found myself searching for a simple VJ tool that acted a bit like a video step sequencer, much like Neon did, but I wasn't able to find one. Well, to be honest I didn't really look as I figured it would be a nice project to get back into Windows apps and check out UWP a little bit.

• Microsoft Visual Studio 2017: https://www.visualstudio.com/.
• Tested on Windows 10 Creators Update.
• MIDI input tested with Akai LPD8 Wireless and Doepfer Pocket Control + MIDISport Uno.
• Developed mostly while listening to https://www.twitch.tv/lost_in_house.
• Tested during development with videos by https://twitter.com/TatsuyaBot. For example: https://twitter.com/TatsuyaBot/status/883635410844254208.
