Incomplete bar synchronizing with style

[Lacko]

For my SX700 I have MIDI file of piano part of a song, which intro begins with incomplete bar. I want to begin the song with that incomplete piano bar and next normal (full) bar to be synchronized with style (saved in first registration of bank).
When I changed that incomplete bar to complete one and added at its beginning one ,,unhearable" note with volume set to zero, midi was synchronized with accompaniment, but song began with drums and piano came later.
How can I start midi file beginning with incomplete bar synchronized with style rhythm without hearing drums before piano?

Thanks for any advice

I have found workaround. Pressing Play MIDI button first and Start/Stop button (or any chord keys) immediately after starts Midi file first and acccompaniment begins synchronized with the next measure.
