What's that type of Synth?

Basically, I'm trying to remember what the synth I want to use is called (I'm honestly not sure it's in Musescore in the first place). The synth sounds very "robotic" or heavy, and when it plays notes it quickly goes up and down the scale if the two notes were far apart. This may also be some kind of option that you can select to make any synth do this, which I would actually prefer. Either way, I don't know how to replicate that into Musescore.
