Is there any obvious reason why I am getting this error (eventually) from my script:

Note:  I have three separate SoundSipher Melodies going on here and I am learning about how to control the start of play of each melody so the melodies start at the same time or could be offset from one another.I don't get the error when line 139 is uncommented and line 169 is commented.  This line marks the beginning and ending of a SoundSipher melody.  I think what is happening here is it's nesting part of a melody when I play the first melody when I put Melody.play(); on line 169 followed by Melody2.play();

I am having a hard time by listening whether the location of [sounsipherscore].play() in connection with other score's has any effect on the timing of when each score starts playing.

Do you have to use constraints to prevent changes to pitch, tempo, and instruments which in certain combinations cannot be handled by java?
