About media .wav files

[StarterPack]

Hi guys, I want to add 3 buttons and each must play a short Wave (.wav) file (This I know how to do it). What I want to know, is it possible that when I click the first button, it must play the first wave file, but when I click the second or third button, it must wait for the first wave to finish before it started the second or third wave. And also it must play immediately after the first wave. I want to make a pattern with chords A,D and E to practice with a guitar.
Thank You

Have you looked at the NeoBookDX plugin ? ... you can setup Markers that are triggered when it reaches the end of the file ... the specified subroutine would trigger the start of the "next" file (until no more files to play).

Thank You Gaev..... I'll have a look at it
