If you want to send y1 to/track/1/fx/2/fxparm/x1 and y2 to
/track/1/fx/2/fxparm/x1x2 etc. , just make four separate messages like
/track/1/fx/2/fxparm/x1 y1
They could be in a bundle together.
If you want to send all the ys to each of the four endpoints then it
should be written* :
/track/1/fx/2/fxparm/{x1,x2,x3,x4} y1 y2 y3 y4
...which is problematic in Pd because of the way text input is
interpreted as TCL at some points, so again it's easier to make four
separate messages. In a bundle they will have a timestamp so they will
act simultaneously.
