playing multiple audio files simultaneously

[Peter Bogdanoff]

Using “wait” is generally not advisable…

I just have a list of all players and then give them all a pause command or set their filenames to empty before playing the new audio.

I saw some instability in LC 9 (crashing), so I’m sticking with 8 until those issues are worked out.

Using a player object on my Windows 8.1 system, LC 7.1.1, I get an error of "could not open that video".  Even if it worked I understand there are latency issues as well as Apple discontinuing Quicktime.
