So the results are strange. I scoped pin 10 (clock, according to the internet) of U118, a 4021B, and when unstimulated it simple read 5 volts DC. If ever I hit a key and triggered a note a whole slew of strange signals would ensue. When hitting the autotune button I would get approximately the same resulting signals. I've tried to capture some of the madness in a series of screenshots attached. Notice these shots are mostly less than one second apart. 

Any thoughts Is this normal Doesn't seem normal.

Sincerely,

Rich Clarke
