Hi Steve, The sequences should all be greater than 32 measures and will all be in 4/4 time signature. Also there shouldn't be any infinite loops programmed. The songs should generally run for approx 120-140 bars in total (including any repeats) and last between 3-4 mins. It was all quite simple stuff back then - there may have been a few patch change requests here and there (mostly at the start) but that will have been about it - other than the note data.
