songsetcurpos(measure)?

while playing i realized that:
g 0
would for a moment set current position to the beginning but next tick
(or beat) is just continuing after the moment when g 0 was called...

in rmidish session i tried:
s; p
and it goes to the beginning and starts again but i suppose that's not
the right way to do loops? am i right?

for me it would be great if just after `g pos` midish will continue to
count from the new current position... is that possible?
