Hopefully any modifications done on the TAE for the MiniMg V should reflect automatically on all other Arturia synths as well. It should just be a matter of recompiling the source code for the other synths. Of course there are issues unique to some of these synths individually...
Yes, you're right.
We are working on many improvements which will benefit to all our synths, even if all the sytnhs have some differents characteristics.
In fact our goal is to reproduce the characteristics of each
synth (oscillators, filters..), and TAE helps to be closer to each
individual synth, with all its particularities.
