While I found some differences between the version 4 and 5 nlfilt opcode,
the main problem seems to be lines like this one:

kacct2 linseg   1/i(kaccnt1), .04, i(kaccnt1), .1, 1/i(kaccnt1), i(kdur1)-.14, 1
/i(kaccnt1)

here kaccnt1 is zero at init time, and thus 1/i(kaccnt1) is Inf. kacct2 is then
used in calculations of filter cutoff frequencies and other parameters, and the
Inf value is responsible for getting the bad output. This is really bugs (there
seem to be multiple such uses of the i() function) in the orchestra, and in fact
I recall similar problems with this orchestra when I compiled the collection of
Mikelson instruments with Csound 4.
