Maybe somebody already has posted about this bug, or has an explanation as to why it would be difficult to have perform otherwise. The bug is this: if you send the message "stop" and then some ramp (like "0 100") to line~ in quick succession (like using a trigger object and have it sequence the messages accordingly, or separating the messages by a comma in a message), the ramp does not end up at the value specified by the ramp as it should. I've attached a patch that demonstrates.
