How to sync Numerology to Apple Logic using MTC
- Start Numerology. If you have installed Numerology's ReWire Driver, be sure
to start Numerology first, to make sure ReWire mode is avoided.
- Start Logic
- In Logic, bring up the Synchronization project settings (Settings
menu, Synchronization).
- turn off "Auto enable external sync"
- Set Frame Rate to 30 fps. Logic will complain and try to use
29.97, but stick to 30fps.
- Set "plays at SMPTE" to 00:00:00:00
- close the dialog
- In the MIDI tab of project settings, make sure "Transmit MIDI Clock
is unchecked". Otherwise Logic may try to transmit both MIDI Clock and MTC.
- Also in the MIDI tab, check "Transmit MTC" (if not already), and
choose a MIDI destination to send sync messages to. You can use one
of Numerology's inputs, or an IAC Bus.
- In Numerology, bring up the Sync Setup dialog (via a menu item in the Numerology menu)
- Choose MTC as the sync input format.
- For the Sync In MIDI port, choose the same MIDI device you picked as the
sync destination in Logic.
- Choose "30 fps non-drop" as the SMPTE Format.
- Since MTC does not transmit tempo, you have to manually set the tempo in Numerology to match that in Logic.
Now when you start Logic's transport, Numerology should chase and follow appropriately. If not, review the steps above and look for any discrepancies. In particular, check the MIDI port you are using to transmit sync, as well as the SMPTE format and start time.
One other thing to note about MTC: Because it uses real-time locations instead of musical locations, it cannot locate with the same beat & bar accuracy as MIDI Clock. This may cause a slight hiccup if you loop the transport of your sync master. This is normal and cannot be avoided.
