on as far as timing.

So I remember correctly that there used to be issues with -X seq.

the -X seq option in current JACK1 is just a backward compatible hack to allow qjackctl and other tools to invoke the relevant stuff.

the actual implementation is nothing to do with the old -X seq code, and is actually a2jmidid converted into an internal client. Note that JACK2 could use this client too - its source code is even in the theoretically "shared" git repo for JACK tools.
