I think the devil is working this quantisation into a patch without adding extra pages or menu items, keeping it intuitive. Plus, making sure the step number allows for interesting rhythmic expressions (loose timing) without making the sequence sound too robotic or limiting. Using the flashing led helps in terms of timing. Also, if you are trying to keep in time with another piece of gear, try using it like a metronome for your sequence recording. I might be suggesting things you are already doing though. Do you feel like the sequencer favours adding one more step than you need, or one less?
