Subjectgogobel bug?
I'm using the csound gogobel physical model in one of my tracks.  The 
first time the gogobel is used it is much louder than the other times it 
is struck.  Here is  a clip from my sco file:

As you can see, I'm repeating a pattern where the gogobel descends a 
little in pitch.  The very first time the gogobel is used in measure 0 
it is nearly 2.5 as loud as the other times it is used.  I'm using a zak 
mixer, sending the output of the gogobel to a filter bank and the 
filters are not changing over time.  Is there a bug with the gogobel 
code or am I doing something wrong?  The only solution I can see at the 
moment is to strike the gogobel on beat 0 of measure 0 with 0 
amplitude.  Has anyone else had this problem??????  thanks..
