I'd like to create a bar of 10 8th-notes beamed irregularly, looking something like this (please view in a fixed-width font): ______________
| | | | |
o o o o o o o o o o
|_____|_|___|_|
if your browser shows this in a variable font and it looks like garbage, the 10 notes are stemmed "up", "up", "down", "up", "up", "down", "down", "up", "down", "down", and all the upwards stems are beamed together, and all the downward stems are beamed together.
In other words I want interlocking beams stemmed in different directions.
Can anyone give me any clues how I might accomplish this? I need a visual solution, not a playable one, i.e. I don't care if I have to trick Finale into thinking I've got 10 bars of 1/8, with barlines hidden, or something else weird.
Many thanks --Luzius
