There are many who don't know what Analog Lab really is. It's a "playback" machine like a jukebox.
The actual sound banks are created from a stand-alone synthesizer like the Matrix 12 and the settings that are used to create that sound are saved to be used by Analog Lab.
Some of the settings can be mapped to the knobs and sliders on your midi controller but with all the available settings, buttons, sliders, patch cords and knobs on each individual stand-alone synth, it's impossible to assign them all to the few controls on a midi device so, the author of those settings have decided to map the ones he thinks would be the most popular to be controlled by Analog Lab.
As an example, I also have the Moog Modular V synth and, a sound in AL that was produced by the modular V can be edited. If there's something I think can be tweeked, I click on the pencil (which shows up IF you have the actual synth) and the actual synth pops up, I then make adjustments as needed, then save it as a different sound bank. The synth goes away and Analog Lab now has a new sound bank.
If you're only interested in the sound from a specific synthesizer in AL3 and you would like to adjust it, you can get the actual synth, install it, edit the sound (the one you want, like the reverb,) kill the reverb, save the new setting and presto, you have the sound you like. But, you do need to buy the actual synth that created the sound in the first place.
I don't know if the trial version will work as well or whether all synths available have trial versions but, you can look around and check it out.
