Hi there @ShannonKick
Which Synth Preset are you referring to Please ? Thre's Leads, Plucks, Pads & different soft-synths like Sylenth or ANA 2 used in this course, so it's hard to guess which preset you're looking for.
Next to this, my advice would be to download & install FL Studio Trial, while the limitation is not being able to re-open "saved" Projects, you can open other's Projects, was actually able to open this session with a trial version of FL.
