About
'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.
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.
Hello! My name is Jack (although I typically go by Egglyberts) and I'm the sole developer for Keysight. I began playing with MIDI integration in Unreal Engine 4 back in June 2019, and then Keysight development began in earnest in January 2020 at the request of a few streamer friends. It released on Steam on June 30th that same year, and evolved substantially over the next four years into what it is today!
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 Official Discord! (See link at the side of this store page). The Discord 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 the Community Hub discussions). 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.

Honestly well done. I'm not sure how to change the note object opacity in OBS. But otherwise 10/10 software.
Allows so much freedom with visualization and catered toward all creators. Perfect for transcribers, arrangers and composers who want exactly what they envision from a visualizer. Perfect for the piano streamers who want to spice it up a notch. Perfect for intensive experimentation and creativity with essentially everything individually custom and efficient with the given presets.
Simple and works on windows + mac

It does the job as advertised. My coworker really wanted me to use it but the keyboard at my work site is so old it doesn't even have a midi outlet. So uhhhh. Oops. It works perfectly on my home piano though. Maybe one day I'll bother to get a midi controller but I have other stuff prioritized. Anyway there are more buttons than I have brain cells.

This is exactly what I was looking for. To start off this review, I use Linux, the distro doesn't really matter it should work on all of them. Runs flawlessly, I had been looking for a pretty good alternative to everything SaaS, because frankly I'm tired subscriptions. A lot of the free software works to some degree, but not for free play. That is, I can't use it to register my own piano playing which just makes them midi visualizers basically. Since nothing worked better than Synthesia for this, I decided to stick with that, and then potentially make my own based off my experience with that, and other software. The problem is it just doesn't work well for streaming, it doesn't look very nice. Then I find this product. I was prepared to spend a couple hours getting it work, considering it says unsupported for steamdeck. Low and behold, it works perfectly. I literally didn't have to do anything. Tried on every native proton, experimental, cachy, and GE. All work. Excellent product, highly recommend for anyone who uses something like SeeMusic or the other various subscribe to remove watermark piano visualizers out there. One time payment, much better than paying monthly.
Fantastic application with awesome visuals! Runs perfectly on Linux too which I greatly appreciate. <3
Fabulous app, but no sound fonts.
I am a music teacher, it makes a great intro to the day to do warm up singing with students. They enjoy the visuals and it gets their attention.
