We've started supporting Studio One 4 projects (currently in beta), you need to have Splice version 3.3.7 or newer.
Currently only .song files are supported , we hope to support Project syncing soon.
Any .song files saved within a cloud based folder ( Dropbox/GoogleDrive/OneDrive etc.. ) will NOT sync.
When opening collaborative projects you may encounter a message regarding MIDI configuration. If you don't have the same hardware as your collaborator you will need to simply click "NO", this does not affect any project data.
