Running the test program
The Nord C1 test program is stored both in Flash and in the BootPROM position U32.

In order to trace a hardware error easier, each Nord synthesizer has a test program.
This program is primarily used in production in order to test all functions.
The functions provided by the test program allow a quick and easy search for possible
errors on the hardware.
