So, I'm not entirely aware if there's an idea like this one already out there that I just haven't stumbled upon yet, but here goes anyways. Essentially, I've come with "the world's best" electronic synthesizer organ; a musical device so state of the art, it can play in the most beautiful and melodious of quality in terms of sound, possesses all the modern devices for imitating virtually any musical instrument, is able to playback songs recorded into it through a "ghost" player function and can record any beat, tone, or sound in perfect timbre, pitch, and tempo. It looks like a perfectly innocent enough modern electric organ, and it even comes with a convenient manual for assistance, but there's a trick to it.
Objectively speaking, it looks like any time a novel sound, song, beat, or the like is "sensed", if you will, by the synthesizer that it doesn't possess, it is itself compelled to possess that sound for itself. After all, it is supposed to be "the world's best" musical synthesizer. As such, it takes it upon itself to obtain, through it's own method, that object, organic or otherwise, producing that novel sound. It's not exactly known what becomes of the object from an observable stand point, save that it seems to disappear from all material existence. All that is known though is that after each time an object disappears around the organ, a new feature, such as a new tempo, pre-set song, or beat, appears in the manual for the organ. I might also add that this isn't the first form this organ has taken, and that it does appear to change itself from location to location it find itself in; it might be a synth organ in one owner's place, it might be a church organ in another.
So basically, I've got the gist of what I'm looking to write, but I'm not quite sure I've got the technical vocabulary to adequately describe what's so special about it, or how I might contain the thing. I've got an idea for metrics of the thing, and definitely have a few ideas as far as pictures go, but words are just failing me at the moment to adequately express the creep factor of the idea. Also, I feel like there might just be a bit too much detail description wise, so there might be fat to trim. There might be a need for some additional reports to attest to the creepy factor of this SCP, so I suppose that's what I'll be working on next.
In any event, I'd really appreciate your guys' input on this idea and any sort of help you might contribute along the way as I develop this thing. Hopefully it goes well!
