Passing a list of the processes you want to output to #'events
will merge them together in the same destination.

(events (list  #&seqone #&seqtwo) "together.sco" 0)

(events (list (my-first-process start-env 60)
	      (my-second-process start-env2 60))
  "ins3.sco" 0)

If you actually need to append them for some reason you can
output the resulting subobjects to temporary seq's before
appending them together in a separate seq:

(events (my-first-process start-env 60)
	(new seq :name 'seqone) 0)

(events (my-second-process start-env2 60)
	      (new seq :name 'seqtwo) 0)

(new seq :name 'together)

(setf (subobjects #&together) (append (subobjects #&seqone) (subobjects #&seqtwo)))

(events #&together "together.sco" 0)
