Yes, there are several ways. There are three examples in rt-examples.scm, 
and you can also look at the source for san-dysth,

The quickest way would perhaps be to reset the positions of the envelopes:
(mus-reset! amplitude-envelope)
(mus-reset! env-devf)

Note that you should do this within the <rt-play> block, because I don't 
know if mus-reset! is thread safe. (?)

If mus-reset! is thread safe, you can call (mus-reset! amplitude-envelope) 
and (mus-reset! env-devf) in the start callback function. If not, you can 
either just create a new instance, or send a message somehow.
