I looked through the Audiobus docs and website for more information on Audiobus & MIDI but didn't find much. Does Audiobus itself transfer MIDI in any way? Or is MIDI completely outside Audiobus's scope?
In the FunkBox video, FunkBox is used as the Clock Master and note generator, and destinations are selected within that app. This seems to happen outside of Audiobus, right? When a recording is initiated from the Audiobus interface in Loopy, it shows exactly when recording starts and ends: is this simply Loopy telling Audiobus when it is punching in and out of recording? Audiobus is not following SPP at all, right?
The reason this is of some concern to me is that conventionally it's the recording app that issues MIDI clock. This is practical because it's usually much easier for a DAW to ask a virtual synth or effect to sync to it, than the other way round, particularly where the playback of multiple simultaneous audio tracks are involved. In the Audiobus paradigm this would mean that MIDI clock would travel from the recording app "upstream" to the source apps, though again if my assumptions are correct this would happen outside of Audiobus.
But the possibility of transferring MIDI within Audiobus itself is an intriguing one. It could clarify the MIDI interconnections and unify the way MIDI clock is handled. Then again, seeing as there's already multiple standards (Core MIDI, Virtual MIDI, and specialized protocols like AKAI's), this might complicate rather than simplify things.
AFAIK, currently there are no iOS DAWs that have implemented MIDI clock & SPP, though they all seem to be talking about it. I think it's the next little bit we need to tie everything together.
Comments?
