@Christoph-Hart I'm thinking that one of the best methods for approaching this feature would be to add it as a distinct playback option for the Sampler.

But before I start coding, I wanted to ask whether you would be open to this as an eventual pull request?

I've got a preliminary Install Plugin up and running for setting a custom installation path for the sample directory. It's embedded within a .pkg built with Packages and I have a rough idea for resolving the one current caveat, which is that installation proceeds first through the /tmp directory. The other major caveat is that this is a Mac OS-only solution.

I'll post the code and .bundle soon. Eventually: a recipe proposal.
