HYPERSONIC ON FL STUDIO 10 HELP

Hey i was wonder if anyone knew the answer to Why when you install Hypersonic and then add it to FL that it plays when you first open it but if you try to play with something else like the kick or press play on FL Studio interface it gets quiet.If its something im missing could you let me know thanks?

I don’t know nothing about FL Studio and how it handles multitimbral VSTI’s.
But are Hypersonic’s MIDI inputs and audio outputs configured correctly?

not sure all i did was install it onto the program. I didnt mess with none of the settings from what they were already on
