Hi Everyone:

Thanks for your replies regarding my need for help. Really impressive  
stuff that people have sent me. However, it does seem to be all about  
Midi. I really need help with audio files (AIFF, Wave, etc.) For  
example, I would like to be able to slow down music without changing  
pitch, and to string two soundfiles together to get one long sound file.

Here is the most recent project that I am having trouble with: I am  
trying to record precisely the point in time that all of the notes  
begin in a sound file. Here is how I am doing it (without success:)

I set a global gNoteTimeList to empty, then start a player and tap  
the mouse in time with the notes in the music using a simple command:

on mousedown
	put the currentTime of player 1 after gNoteTimeList
end mousedown

I then set the callbacks of player 1 using this script:

repeat for each line L in gNoteTimeList
	put L & ",PlayTick" & cr after theCallBacks
end repeat
set the callbacks of player 1 to theCallBacks

Then I import into my stack an extremely short sound file called  
"tick" that is the sound of one tick of a clock and use the following  
script

On PlayTick
	Play audioclip "tick"
end PlayTick

to play it. When I run the player, it's pretty good, every time I run  
the player, "tick" plays in slightly different places. After lots of  
testing, it seems that the computer is inexact in both recording the  
mouseclicks and in playback of "Tick". I think I am probably just  
using the wrong tools for this project.

I would really like to stay inside Revolution to complete it. Does  
anyone have any ideas?

Thanks
Fred Moyer
