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)
