A Whole bunch of notes randomly mute for no reason

[DalekWho08]

So i noticed that a ton of instruments make no sound at the moment. first it was the electric and grand piano, but those are now fixed,

now it's every single instrument in the orchestra section, the ragtime, electric classic, and grand classic, all of the synths except for the 8 bit ones/ regular synthesizer, (synth pluck won't even place) almost all of the guitars won't even get placed/make noise, and all the drums and percussion

it could be a bug on my end, but does anyone else have a similar problem?
