ok good, that should have worked.

pinmux was set up to run from the coriolis2 directory (relative import by

so as not to have 2 copies of pinmux i created a symlink.

really it should be done as a python package (with a setup.py) i haven't got

no i haven't got to that, it is for later when adding the full core (ls180.il)

we are still at the drastically-cut-down handcrafted ls180.vst stage.

once that works then adding the full core and trying that is the next stage. 
once that works i will tag it so that it can be snapshotted and repro'd any
