seq~: sample/control rate timing issues

I have a seq~ (play, record and overdub all on) and in it an event is stored at 0.0 that signifies the beginning of a new bar. If a new MIDI event arrives to be recorded just after that moment, say at .001 (of what should be say, bar 2), it won't be tagged with the new bar identifier and will get recorded as though it occurred at the very beginning of the bar prior.

Basically it seems that the event stored at 0.0 doesn't actually leave seq~ until some number of ms later than the exact sample-accurate moment that the ramp is at 0. Does this sound right? Is there a setting I can change or something else I can do to cope with this?

Strangely, I don't THINK I ever ran into this issue when I was running everything completely in Max for Live, but it's been a frequent issue since I transferred my set to standalone Max.
