Piano Program

[Raf vanduffel]

I'm working on a project in LabVIEW to create some kind of piano. But i have encoutered alot of problems, and i can't figure them out.

I keymapped the piano buttons to the sound in the block diagram. But when i do continuously play i get all sort of weird sounds. I think it's weird because my buttons are setup as latch when pressed.

I also would like that my sounds get played directly and dont wait before a previous sound has finished playing.

I tried to record my sound that i played, but i kept getting the message to overwrite the while were my 'song' had to be stored. I would like to know how you can start recording and stop recording by pressing a start and stop button or record button. And the sound get's saved in a folder as a .wav file

If you want to test this file, you need to change the sound paths first, but your probably knew that already.

Update of my program are always welcome 🙂

Hi,

I changed your VI so it's easier to modify. With your VI and with my VI everything sounds OK.

Hi Rafvandu....
I spent some time with your piano and this is what I came up with.....it could be better ...I am still working on it.
