Play music note during pressing time of a button

Drawixe

Hello,

I would like to make a musical project, and I would like to make a sort of piano.

But by pressing a button I only can play note during a fixed number of beat and I would like the project plays the note during the pressing time of the button and WHILE I'm pressing the button (not after).

If you've a solution

I think there may be a pause between each note, though.

For instruments that fade fairly rapidly (e.g. a piano; instrument #1 in Scratch), this should work. I'm not sure there is a nice way to do it with instruments that offer more sustained sounds. The major drawback of this solution is that it requires 1 sprite for every note:

But then, the note will only play for two beats. The note needs to play while the key is pressed. This is better:

Your concern is certainly valid, I just don't think playing the same not over and over again is a good solution. Since on a real piano notes fade fairly quickly and don't sustain forever while you hold them, I preferred my solution.

There is two problem with your both solution:
First, in your answer MoreGamesNow, when I stop pressing “b” key, the note does'nt stop in despit of the volume being 0. So note is playing 2 beats everytime I press and no matter how long I press.

Secondly, in your answer Chibi-Matoran, the note only repeat itself, a real piano doesn't do this, I want (like MoreGamesNow says) the note fades.

But I'll use your both answer for another project.

If you find any other solution ?

Ok your solution is valid on web version of Scratch MoreGamesNow but not on 1.4 version.

I need to work offline, I'll use this project on an event so no internet connection. Is there a solution to download the web version of scratch ?

Doesn't work well on Ubuntu, because of Adobe Air.
Adobe Air (even in old version) doesn't work well on Ubuntu 12.04

Okay, so the problem with Scratch 1.4 is that the volume of instruments does not update for sounds already-being-played. However, it does work for recorded sounds, so one could use a script like

The problem being that you have to import an audio file for every note

Yes, and for every instrument ^^'
So I've installed windows on an old computer and installed Scratch V2.

Thanks to you

What I did was go into the scratch library and insert the piano notes, then I made the code above and it fixed the problem……

Thanks scratchingboy18, I appreciate the help, but then you would have to upload each sound into each note.
