Just in case anyone's curious, here's how the problem was solved. The
task, if you recall, was independent control of 10 blinking LEDs from
the digital outs of the Arduino. I ditched the Firmata and used some
basic Arduino example code instead. LEDs draw about 8.5 mA each in the
end (using Kingbright ultra bright reds with 330R resistor) so it's
quite safe to run the whole thing from USB power even.
Arduino code and test patch attached.
best!
