Hello! I am currently trying to code a trial where participants press a key at a specific moment in a trial. There is a moving bar that loops, and they need to press the space bar when it lines up with certain shapes in the background. Depending on where they press the spacebar, a different sound is played. And each loop does not have the same sounds as the previous loop. There are 6 loops total. How can I code Inquisit to play a different sound based on the frequency of key presses, and how do I link that to a particular key?

Please provide example code. It's entirely unclear what you refer to as "loop" and how you implemented it.

<values>
/ noteCount = 0
</values>

<trial instructions>
/ preTrialPause = 500
/ stimulusframes = [1=tasktext; 1=musicline; 2=line1; 3=line2; 4=line3; 5=line4; 6=line5; 7=line6; 8=line7]
/ validResponse = (" ")
/ responseTrial = (" ", synchrony)
</trial>

<trial synchrony>
/ preTrialPause = 500
/ stimulusframes = [1=musicline; 2=line1; 3=line2; 4=line3; 5=line4; 6=line5; 7=line6; 8=line7]
/ validResponse = (" ")
/ ontrialend = [
        values.noteCount += 1
        ]
</trial>

Right now I'm trying to have noteCount increase by 1 for every key pressed. And I would like to use the number of key presses to control which sound is coming out. So if noteCount is 1, 2, or 14 for example, it plays soundA.

Please provide code one can actually run, i.e. that includes the definitions for all elements referenced. Also, if your code requires any files (images, sound files) you should provide those as well. Further, please comment your code and provide more than vague one or two sentence descriptions of what it is supposed to do.

When the musicline overlaps with the third and fourth rectangle, it should play noteG. The participant is essentially trying to play the rhythm of a song by pressing the spacebar at the right time, which is indicated by the rectangles. 

That's not going to work this way. You'll essentially have to break up the trials and animation in to one per line, a continuous animation in a single trial cannot work because you cannot change what the trial does once it's runing (e.g. play a different sound depending on where the animation is when the space bar is pressed).
