If you’re using an LFO in the instrument modulations, this will always reset on new notes. If you want to sync it to Beats instead of Hertz, then simply toggle the timing mode.
If you’re using an LFO in the instrument’s DSP chain, then resetting the LFO involves the use of either a Velocity Tracker or a Key Tracker, linked to the LFO’s Reset parameter. This same technique applies whether it’s inside the instrument’s DSP chain, or outside in the track DSP chain.
