Yes, I have wondered whether the USB external that Chipp has
abandonded could be adjusted for a specific device like this. May be
Chip should discuss this with them (I don't think they have a
distributor in the US, so this may be a business opportunity).
I may not have said it clearly but the company actually tested that
their device works fine with Rev using AppleScript. They say the
syntax is like
do "set SERVICE output value 85" as applescript
to set the output value to 01010101 binary, for example. For many
control applications, using AppleScript can be just fine.
They are just looking into developing an example stack for Rev if
there is enough interest.
