Currently there is no easy way to do that.
There are several things that help but more tricky than you would expect (copy&paste doesn't use windows clipboard. It's internal memory).
Ways to copy data:
Export the presets of machines (Parameters, open preset dialog)
Export single patterns (File - Save, and select as type psycle pattern)
Export wavs (it does not export instrument data: Save button previous to the wave Ed one)
With the new Psycle engine it may be possible to implement easier ways, but I don't have a schedule for that right now (Concretely, it is able to load more than one song)
(Ps. It is possible to open two Psycle Instances, see Settings-Configuration-Keyboard an Misc Tab).
