Test signal mod question

Post by Qfactor »

Can the 1KHz test signal be changed to a user defined frequency?
Looking at the schematics, I see that the test signal comes from the MCU directly. Can it be reprogrammed?
This would be a great extra feature if it can be tuned to 440Hz to function as a tuning reference for musical instruments!
Can it? :?:
