Within the Sequencer you can select a destination for each sequencer track (soft knob4 above the display) where u can choose the cv outputs and set a different voltage for each step. Multiple tracks can send cv out to the same output, which can be interesting with different track lengths. If you instead send CV straight from the LFO the way you do, you could still sequence the LFO´s frequency and amount to have different cv values at different times going into your modular. Remember the sequencer can go as low as 30 bpm.
