As far as I know the KORG apps do not send any MIDI whatsoever. Your only hope would be to run a master clock app that fed the KORG apps and the hardware simultaneously.
However, I am unsure whether any of the KORG apps will slave to incoming clock. I can't find a definitive answer to this, although I saw a tweet that iELECTRIBE had received an update that included sync features.
Also the KORG apps can be started/stopped with a CC message (which MidiBridge can convert from a MIDI start/stop command), so you could start your master clock which will start the KORG apps via MidiBridge, but no guarantees they will remain syncing nicely with whatever is syncing properly to the master clock.
