Re: [The_Cyndustries_List] ZO group & Re: ZO w/ audible Jitter on Pulse/Square

2006-08-04 by Michael Zacherl, Vienna/Austria

Hi Morbius, Mike, Cynthia & All!

I'm sorry, it was dumb that I didn't provide any further information 
about the configuration.
To me it was that clear and simple that I just didn't think of it - 
sorry. :-(

The only patch cable I put on the ZO was the pulse out to a LP-filter.
Nothing else.
By "playing around" I ment flicking switches, turning knobs etc. and 
check what changes while doing that.

The jitter is a frequency jitter, I'm pretty sure. It sounds like if you 
apply a deeply filtered noise at a very low level to the exp-input of a VCO.
It's better audible at lower frequencies (~200-500Hz) and basically not 
very strong.
I thought of a bad cable, a loose connection and tried others - no luck.
The other waveforms are stable (checked with the same cable and filter, 
just plugged into the other sockets on the ZO).

So far I didn't set up my scope and counter to check this (will do this 
on the weekend) nor I found time to check the other two ZOs (also doing 
this WE).

I went through the manual even before I purchased the ZOs as part of the 
decision making process and I'm looking it up quite often. Sometimes I 
wish there would be more detail - like what's the best input signal 
range to bring the the FM-index input to full effect? At least I didn't 
get a clue from that what I could read.

Yesterday I used the ZO in the rehearsal the first time and I'm pleased.
I was doing pretty noisy stuff (like I was asked to do so) and smoothing 
the sound later on and get rich varying timbres was a breeze. I started 
to love it. Of course I was not even scratching the surface and I've to 
really explore the ZO and investigate it's functions and ranges.

So far there is one thing I'm sorry about: The morphed signals don't 
deliver nice transients when set to squarish waveform in LFO-mode.
I played around and alternatively feed the pulse out and one of the 
morphed out to a LP-filter with high Q so that it rings when pulsed and 
there's clearly a difference (the pulse is much sharper).
But I'm sure that's a matter of principle as how the morph circuitry works.

I'm really looking forward to all the new things I can pull out of it.
Now I've to put more pressure on the cabinet maker that I get my new box 
soon so that I can fit the other ZOs as well. ;-)

   Thanks, Michael. (still w/o Internet @home)
