Support in aldrin is via the libzzub project, which added recently support for the psycle plugin API.
We keep an eye to that project, but haven't verified first-hand that the plugins are currently working there. There shouldn't be any big issues, but i remember bohan saying that they played notes one seminote higher than it should.
If you want to do some test, and report what's not working, we can check if that's an issue.
In any case, let's continue this conversation in the tech boards, not here (This forum is more about development *news*, not bugs)
