change data from keyboard ( ex: a ==> numeric = 15 )

[jasjas]

i want to make a simple Piano ... i got note equivalent frequency and i did a numeric case that pass one frequency to the wave output so changing the numeric simulate piano

i only could set decrement/increment from the keyboard  for numeric value  this is not efficient

i want to simulate the keyboard as a physic piano so when clicking 'a' correspond do ... this mean that i want to change on clicking 'a' the numeric value to 0

the project is attached

Hi jasjas,

use an event structure to detect keypresses. You will get an ASCII code for the key that you have to convert to your frequency.
You can directly connect it to a case structure where you define a frequency for each relevant key. Or you use a lookup table...
