if you want something like labview, why not just use labview?
I've not used the lynxmotion sequencer for servos, but I've looked into it before and it looks like it has a decent amount of documentation and seeing as they use it for their hexapods and bipeds i'd assume its fairly powerful.
honestly, If you have specific questions about it why not email lynxmotion and ask, they could give you the best answer.
And, I would recommend you away from GUI programming. Yes it is easier to just drag and drop, and you dont need to know programming all that well, and labview does offer a lot of features, but I dont feel like those kinds of programming tools give me the control I want. i would say try to learn C or whatever language you need to use to program with. In the long run you'll be able to do more writing your own code rather than using a GUI such as labview
