You may want to look at the RTcmix implementation of these objects
included in the max/msp rtcmix~ object (latest version here):
http://music.columbia.edu/~brad/rtcmix1.39/
I put envelopes on a lot of the excitation and the output amps for many of
the models, plus you can do dynamic changing of model parameters (when
allowed by stk).
I'm working on a new release of rtcmix~ for both OSX and Windows,
hopefully will be out in a week or so.
