Thanks a lot Kjetil! I thought of the scheduler but I had rather you
commenting the issue.
I might be generalizing but Physical Modeling gurus often take durations
between half seconds and five. This might work for delay lines or at
least to get things working.
Looks like I have to sit down and read your LAC-2008 paper because
syntax is a bit different. And speaking of code simplification, wow!.
