Compiler/OwlControl errors

I am compiling a PD patch containing a simple table-tabwrite~ - tabread4~thing to delay, loop, glitch with.

The compiler here gives me “successful”, though reporting warnings…

However, when i load sysex via OwlControl
- the Owl (pedal version, firmware v11) goes red, then reports much more than 100% CPU, varying.

  • Most prominently it reads “Heavy assertion failed in __hvtabread_if line 70”. Resulting patch hangs on a short cycle (maybe even one block) and doesn’t play. EDIT: Error was not to specify a size for the table as an argument. MUST be done.

  • Descriptive names for faders/controls don’t show in OwlControl.

What could i possible have done wrong?

Patch is already here, though private, until finished/working.

Thank you for any insights in advance.
