Być może tego nie próbowałem, ale musiałem to widzieć.

Próbowałem, means ‘I tried (it)’. It also means ‘I tasted’???

Yes, exactly! It’s the default word for “to try sth”, but also for “to taste sth”.

Another verb for “to taste sth” is “posmakować” (derived from the noun “smak” = “taste”), although it sounds rather poetic and isn’t used that often.
