You're welcome.
I vaguely remember that my OB-8 went into a similar state many years ago,
not from changing RAMs, but from simply sending MIDI data from an
Ensoniq ESQ-1.
But I didn't know about the a button combination to *reset* that value.
What I (vaguely) remember is that there was a method to *write* such
a value, where one of the "C" keys would mean an intervall of 0.
