So, I'm halfway through soldering up a 4029 to drive a 16-step sequencer, and now all this. Although, I suppose a bounce would be possible with my current design.. Patch start and end gates from the sequencer through an OR to a flipflop toggling the Up/Down.. yeah.

Not sure whether it would reliably bounce "internally" or "externally", if you know what I mean (between the start and end, or "around" them). Does this? I haven't thought it through.

I see. You've given me the idea to bring the carry-out out to the panel; that could be useful :)

also, I'd looked at the 4516 before, don't know why I forgot about it when it came to choosing a counter for this sequencer thing.

I was just going to tie the jam inputs to ground, too. Really, bringing everything out to the panel gives you the most options, even if it means a lot of patch cable. And pull-down resistors give you a "sane default" when nothing is plugged in.
