Can sparky pwm smd led controller pcb be used for 16 button configuration?

<font face=“Arial, Verdana” size=“2”><span style=“line-height: normal;”>Hi, I am actually building a midi controller. I want to be able to control the Ulia Flash LED’s of each button but that seems out of the question without lots of programing. So What i was thinking is to have 7 of the buttons wired separately and the other 9 buttons all wired together. Does that sound like something that will work? This is my first time even soldering. Now that I have bought most everything need I realized that I should have went the solder-less route but its too late now. So does this sound like something the sparky could do? Please any information/advice helps. </span></font>
