triggers and gates can be mixed, yes. a trigger will override a gate, however, if multiple rows are acting on the same output.
the old link function doesn’t exist. this is a reworking of the whole concept, more similar to flin. you can, however get some link-like results by having one row RESET other rows, not just itself. you can also have one row just be a master RESET for the rest of the rows (this row could reset itself, or not.) TT can RESET a single row or all at once as well (0 does a full reset).
II MP.STOP x is also implemented in TT.
you can use the STOP rule in one row to halt another row as well.
so lots of new options, and you’ll get generally different results. the old version is still musically interesting for sure, but it has a narrower set of configuration possibilities.
