Control start of lfo of tremolo

Hi, I have seen a few mentions of this on the board, but nothing that relates specifically to my needs.

I am trying to control the start of the tremolo lfo. I am playing a pad sound with a slow attack, so I cant use the retrigger feature on the pattern trem as I have no pick attack to trigger from.

I have tried switching the tremolo patch on in time to the track, but it seems the lfo plays continuously.

I am playing to a click, so I dont want to have to tap in a tempo manually. Is there a workaround? I can’t see any midi cc that would help.

I have seen feature requests for this and more, but wondered if there is something I could do to get what I’m after now.

TIA
