Can anyone confirm whether the VSC DXi software synth with PowerTracks will accept and use SYSEX data please?

I have a SYSEX event to send a Scale Tuning Adjust message at the start of a MIDI track playing in PowerTracks to the VSC DXi synth. As far as I can determine the message is being ignored by the synth.

Thanks,
John
