VX-351 Faulty S&H Smooth output?

The Moog Forum Minimoog Forum

Okay, I know the answer to this but will ask anyway..

Finally got to have a proper play with my VX-351 tonight. With a very simple setup:

  1. S&H Step output into my MS20 Filter control

you get a S&H modulated filter cutoff on the MS20. Nice and random, ranging from fully closed to fully open as expected.

However,

  1. S&H Smooth output into my MS20 Filter control

this result in no modulation! I am expecting exactly the same as in 1 but ‘smoothed’ version. There is definitely no modulation going on..

So, its faulty I presume? Not a problem if so as only a couple of weeks old so well within guarantee..

Thanks for any comments..

Have you tried going into your voyager? Could it be a V/Hertz problem?

Hi - yes, I have tried this. The effect (or lack of) is the same if I try to modulate the MS20 or back into the Voyager. Besides, the MS20 is only Hz on the keyboard triggering, everything else is standard volts. Also, I am successfully modulating everything with everything with my Voyager/MS20 setup, it is just the Smoothed S&H that has no effect (and Noise as discussed in another thread).

Thanks for the reply,

Thanks for the replies on this. I got a replacement yesterday from Turnkey and all is now well. Was planning on going on Thursday but decided against it!

Have not actually tried all the functions yet but the smoothed S&H and noise both now work.

Thanks again,
