OK, that was a tricky one to figure out.  You have two problems, one causing a crash:

1. your knobs *and* the objects they control are connected to the “basicMenu” menupage object.  That is causing the crash (although, that should be filed as a bug).

2. your “statement” strings in the knobs are not correct.  They need to be in %f form.  $f for unformatted, %0.3f for zero-leading with 3 decimal places, etc.

I’ve attached a corrected sigfile.
