I got an error when trying to compile a patch containing a beatmachine object in 1.0.12.
Some others pointed out that you must have an equation set in the "beat" field.
From a user standpoint this is a little frustrating - as I didn't understand the console errors until after I had posted the error and had others explain it.
From a developer perspective - if it were me - I would have a default algorithm set for the user to have immediate usability.
I look forward to playing with it now that I know how to set it up.
