You can try this:
Load this in a Biab VSTi slot midiOut64.zip (you may need midi on that track for the VSTi to be active ?)
Set it to MTC LoopMidi and set Studio One Midi In to that also.

Go to Options > Advanced > Synchronization Tab.

Sync to External Devices: Click this box to make Studio One follow incoming MIDI Time Code (MTC). Note that some MIDI devices only transmit MIDI clock data, not MTC. Studio One requires a greater degree of accuracy than a simple MIDI clock can provide. For conversion from SMPTE, an outboard synchronizer is required. For additional accuracy, using an external word clock (master) is recommended.
MIDI Time Code: Select the device that will receive MIDI Time Code (MTC). The gray field to the right of the device name indicates the current status of MTC transmission.
MIDI Machine Control: Select the device that will receive MIDI Machine Control (MMC).
