Tremolo LFO to Tempo sync when tape speed is changed

Hello, i’ve noticed that the tremolo LFO speed syncs exactly with the master tempo, irrespective of whether the tape speed is 1:1, or something else. This means that when recording at different tape speeds the LFO vibrato is no longer in sync with the track.

the only solution i can think of is recording with a tape speed of 1:1, which kind of defeats the point of what i am attempting to do.

Has anyone successfully achieved what i am trying to do?
