take sequential switch 8>1 from ml, or seq3 from fundamental.
aim: press run on a clock and get the patch playing in sync.
trigger the reset inputs. expectation, everything is primed, ready to play.
press run, clock starts.
first clock pulse. expectation, play first note. but seq3 and seq switch move to their second positions and play those notes, with associated gates and outputs.
some sequencers, eg piano roll and scorovnik, reset to before the first note and the first clock has them play the note in the first position.
