i have some great four-bar audio clips although they are only interesting for sixteen bars.
this online collaboration label -
http://wemixseries.com/ - would be interested to know about the Machine release.
i have not submitted any of my four bar audio clips for their online free compilations, although from most of the emails, the organization seems to be simply to release electronic dance music.
fairly inappropriate mention i guess, in that many elektron users will not be in the dance music genre, thought i would mention anyway.
