hello every one,

I am new here && new to coding && need some help lol. i have 3 buttons that i want to store currentButton and LastButton but i am having some trouble with this using the bounce.h library.
can anyone please let me know the best way to attack this? I have attached my code please have a look. also my main goal is to control the filter of each button and store that filter value so when i press another button i can edit the new button without changing the first.

Your code looks like it will rapidly & repeatedly reprogram the filters and mixers every time loop runs.

Code: 
  if (currentbutton == 0)
  {

    // quick and dirty equation for exp scale frequency adjust
    float b0freq =  expf((float)freqknob / 150.0) * 10.0 + 80.0;

    b0filterstore = freqknob;
    filter1.frequency(b0filterstore);
    filter2.frequency(b0filterstore);

You probably only want to change this stuff when the button is actually pressed. So it should probably go inside the if checks for fallingEdge.
