omniCLOCK isn't sending clock to my synthUpdated 6 days ago

omniCLOCK only sends clock while the DAW is playing. Press Play after the setup below.

1. Put omniCLOCK on its own MIDI track. In Logic, that is the MIDI FX slot, not an audio effect.
2. At the top of the plugin, choose your hardware's port in the Output menu.
3. Turn off the DAW's own MIDI clock for that same port. Two clocks on one port is the usual reason a synth ignores omniCLOCK or runs at double speed.
4. Set the hardware to external clock, sometimes called slave.

In Cubase, also turn off Preferences, then VST, then Plug-ins, then "Suspend VST3 plugin processing when no audio signal is received".

The manual walks through this in more detail: omniCLOCK manual
