Hello atotheroh and welcome to these forums. You'll find many helpful people here and a lot of useful information.
Yep, that is certainly possible. What you need is Parameter automation. That will let you control the Filter parameter of the plug-in synth, changing it at different times - either by editing points in the Arranger, or from a MIDI keyboard controller.
To get started (there is much, much more that can be done):
- open the synth GUI
- twiddle the Filter Cutoff knob
- click [Param] and select "Show track envelope"
- there should now be an Automation Envelope lane in the Arranger, its height at any point shows the level of the parameter
- drag the lower edge to make it taller
- insert some envelope points on the line (Shift+click here)
- drag the points or the segments between the points up/down to change the envelope
- in the Track Control Panel (you may need to drag the lower edge to show all the buttons), right-click [TRIM] and change it to [READ]
- now play back the track and you should see the Filter Cutoff control move and hear the sound change.
