Mystic38 is correct, that method now supersedes my method because SPA just got updated to sync properly with Cubasis. Also the issue with the sync glitching when Cubasis repeats a loop is apparently due to an unexpected extra clock signal being generated by Cubasis - that information came from the developer of SPA. The looping glitch can be avoided by using my method involving MidiBridge, but it’s just “patching up” the sync and it has side effects on tempo with other apps running. Ideally Cubasis will be fixed so that MIDI clock output is standard format, and hopefully an arpeggiator will be added too! But it would have to be as good as SPA to make it worthwhile…
