Riguardo questo software

'Keysight' is an Unreal Engine powered real-time MIDI visualization platform aimed at piano-focused video creators and streamers. It aims to provide the most comprehensive, configurable and feature-rich set of visualization options in a single piece of software.



Please be aware that this program is purely a visualizer for content creation, and does not produce sound. Keysight is not a virtual instrument or learning tool.

Features

• Render-to-video
  Export your MIDI files to perfect quality .MP4 video files. Supports audio file down-mixing, branding image overlays, and any resolution / aspect ratio / framerate.
  
• Customization
  Configure everything down to the finest detail and make your own truly unique visual style, complete with custom image support. No effect is mandatory; add some simple glowing edges to your midi roll or go wild with hue-shifting backgrounds, millions of particles, GIFs and light bars.
  
• Sharing
  Presets can be imported and exported, with any attached custom images, to a single .KSpreset file. Access the incredible creativity of the community in just three clicks.
  
• Augmented reality
  Keysight is fully 3D and accurately modelled. Freely position the camera and enable semi-transparency to achieve "magic piano" style AR visuals; no image-based 3D warps necessary.
  
• Remote control
  Use websocket connections to remotely automate preset changes, camera angle switches, or a number of other actions. Take live-stream chat interaction to another level with chat-controlled visualization. (Requires implementation on the part of the user. See Steam guides.)
  
• Randomizer
  Generate new visual styles in a single button press with the randomizer. Tune the generation to your needs with 96 configurable chance branches and the ability to re-roll specific effects within a preset.
  
• Simulation
  Bring out every detail in your music with rich simulation. Every effect can be altered in intensity with note velocity, particles can be blown around by note activity, and all three pedals contribute to activity calculation.

A note from the developer

Hello! My name is Jack (although I typically go by Egglyberts) and I'm the sole developer for Keysight. Back in June 2019 I began playing with MIDI integration in Unreal Engine 4. Keysight development began in earnest in January 2020 on the request of a few streamer friends, and it released on Steam on June 30th that same year.

While originally targeted at streaming, Keysight has now grown into a powerful, flexible MIDI visualization tool that can serve many purposes. If you're looking for some inspiration, check out a myriad of community creations over in the very active This is also a great place to get help if you have any questions; I will often answer questions within minutes (or, in the worst case, within a day).

Finally, if you happen to be a serious content creator: I do offer a paid service to build custom Keysight implementations to your specification (more information available in this video). To be clear, this is not aimed at the overwhelming majority of users! Keysight is a fixed price, and it's yours to use for any content creation you desire. No subscription, no in-app purchases, no DLC. But for those "time is money" folks out there, I am here to help!

PS., if you're interested, give the demo a go! The only demo restriction is that 50% of note-on events are dropped at random; all features are present and anything created in the demo carries over into the full version.
