Hey Mdimm,

After reading this, I had to try it too, and experienced the same problem. No difference between the A-110 VCO or the A-111 hi-end-VCO.
I tried the A-114 ringmod as well as my Lindhof-ringmod and nothing was audible, not even visible on a oscilloscope. Might be the effect of the 1496 chip used in both ringmodulators.
But try this: Take two VCOs having the same frequency and sync them additionally, then plug both sine outs into the ringmod. Now you have a doubled frequency although the doubled sine is modified a little bit thru the ringmod. Lacking a second A-110 at the moment i had to do this with one A-110 and one A-111. Don´t know how well it will work with two A-110s.

best,

Paul

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!

Mdimm
