V-Collection contain all the individual applications that Analog Lab 3 can host and use presets from. If you don't have the full application for a preset, then there are parameters, that you can't access in Analog Lab 3.
Analog Lab 3 can also use presets from here:
https://www.arturia.com/analoglab/sounds and from third party vendors you may find that create any.
Analog Lab 3 can add functionality to V-Collection. But Analog Lab 3 can't do all things, that you can do when owning the individual full applications where the presets have been made.
In my opinion you actually get a lot for the money in Analog Lab 3. You have many edit possibilities. But if you prefere to go very deep into programming your own presets, then you might need the full individual applications. Keep in mind, that a full applications sequencer can be different from another, if they have a sequencer, - and so on.
The sounds in Analog Lab is made in many applications. Only the Multi presets is put together in Analog Lab 3.
If you only have Analog Lab 3 for this price:
https://www.arturia.com/products/analog-classics/analoglab/overview -
and you do not have any full individual applications for the price they have individually or the whole V-Collection for this price:
https://www.arturia.com/products/analog-classics/v-collection/overview ., then there will be some things you can't do, and among what you can't do is programming steps in the individual full applications that have a sequencer.
What do you own?
