I've been trying to use my A-114 to double the frequency of a waveform (as
suggested by some articles about modular synthesis), but couldn't get it to
work.
(After all, a ring modulator gives the sum and the difference of its inputs,
so having the same signal at both inputs would give only the sum, the same
waveform one octave higher, yes?)
It seems that the sound doesn't change much at all if I send the same sine
wave trough both its inputs.


Does anyone know why this doesn't work? Does it work on other synths?

Desperately trying to get something in the range of 15000-18000 Hz out my
A-110...

Thanks!
