Audio Triggering + Mouse Event latency

[René Micout]

Fred,
1. PlayCommand Agent X (for Mac - available also for Windows) is a part (engine) of Shakobox :

2. For your problem : why not using something like a looper, example :

> This discussion reminds me of my problem.  I am a pianist and am trying to use Revolution in my concerts. A typical performance starts with me playing on the piano alone -- and at a specific moment I bring in a recorded accompaniment which is in a Player in Revolution. I do it with a foot pedal that generates a mouseclick (my hands are busy.) When I press the foot pedal Revolution starts the player which is already loaded with the soundfile. Here's the problem: if Revolution loads the file and I press the foot pedal within about 20 secondso, the sound plays immediately -- no problem. But if my piano solo part is longer than that, it seems that Quicktime (or Revolution?) goes into some kind of hibernation mode and now when I press the foot pedal there is a delay of perhaps a second before the sound plays. This is death for the performance! So now I have to press the foot pedal about a second before the sound starts; it is really a drag! Any ideas? 
> 	Based on this discussion, I gather it would be quicker if I could get the foot pedal to generate a keydown? Any ideas how to do this? How do you make an external mouse generate a keydown instead of a mousedown?
> 	Is there any way to set Quicktime to not go into that hibernation mode? I have Snow Leopard. Would it help to move to Quicktime Pro? Or Quicktime X?

>> Hello Anthony,
>> I just returned from a trip and I discovered the discussion. For months (years...) I work on this problem and the best solution I've found in terms of responsiveness is to use PlayCommand Agent X (see Jacqueline web site for that) which controls the QuickTime synthesizer via AppleScript. I have a (Mac) prototype in progress (for iPad in final) called "Exapad" which is based on the principles you have mentioned and which uses "MouseDown" to start the sound and "MouseUp" to stop it. Hare are scripts extremely simplified (because in application chords can be played and arpeggiated) :
