after update of piano led visualizer, change of steps in sequencer via CC no longer works

[fermaton]

I did an update from the html page of piano led visualizer.
After the update, my previous sequences got erased, and I created a new one from scratch.
I had selected the CC66 as method to change steps in sequencer, but after the update, this method no longer works.
I tried to use another CC with different values, but I can only change steps by pressing the button in the html page.
Thank you
