how to sync an LFO/wobble bass made in synth 1 with tempo

[ezmoney]

Hello,
I've been on the path of learning how to create electronic music with Reaper and I'm loving it! I am extremely new to this (electronic music in general.) I've learned how to create the "wobble bass" sound with synth 1 by setting the LFO to lP12 (low pass filter) and automating the LFO speed (using envelopes). The problem is, I can't get it to sync with the tempo. Is there a way to do this? I want to adjust it faster and slower, but it would be nice for it to sync half tempo, full tempo, double tempo etc.

Sorry if this question is basic. I've searched Google for quite a while, but unfortunately, there are not a lot of tutorials for this style of music in Reaper Thanks!

On Synth 1 there is a tempo sync button in the LFO section
