SynthModules

I assembled my new PSIM tonight (with the help of disassembling one
that Brice built for me 2 years ago).  It works - but when run
identical programs (gc-sah-sr-nq-djb.bas), the two modules output two
different pitches when sampling the exact same source.

Is there a way to calibrate the modules to be identical?

p.s.

Assembly really wasn't hard - and I have the module working now. 
Those of you who don't have their modules should really consider this
option.... 8^)
