not out of the box... After import, the adjustments needed are
(at least) to
1. replace dspstate~ (not yet in cyclone) with, for example
[r pd]->[route dsp]->[samplerate~]
2. replace '$1' (the default Q) with [f $1]
3. replace each of the three [/~ 1] with [/~]
4. remove duplicated connections to [outlet~]s (this is a bug in
the import code, have not fixed it yet)
