Sothere are two syntronik apps in it store, cs and one without cs
The non cs has more instruments for free the cs has 4.
However the deluxe gives you all instruments in both, at least i think LOL
Look at the price difference for the presets
30.99 for cs
79.99 for non cs
Per your post it appears that the upgrade price from the non-CS version to "full" is not discounted for the "50% off" sale, and since the CS version is free, that would appear to be the cheapest way at the moment to get either the full or the deluxe Syntronik app (unless you prefer to put in your toe with a monthly subscription).
Syntronik deluxe is all presets and all instruments and Syntronik (standard, "full") is an earlier version that comes with less of both (though you probably want to count presets, not instruments, since this is sample based).
Then there is also the desktop version which will have more 'sound' - it weighs in at 50GB vs. a little over 6GB on iOS. - That might also have more presets. (I see 2000 used as the number there vs. 1600 for iOS, but then I do not know how the total is counted - there also are "Multis" presets.)
