Doepfer

Here's one for the circuit heads...

I'd really love to have a MUCH lower shift range (somewhere below 
1Hz, as opposed to the standard 50Hz) on my A126.  Any ideas?

Thanks,
Kevin

If somebody has a schemo to the Frequency Shifter I could 
probably figure this out how to decrease (lower) its range.  I've 
done a bunch of mods to my Analogue Sys and Doepfer gear 
with great success!.

I am seriously considering buying one of these shifters,  would 
love to hear an audio test though to see if does what I need it to.  
So, if any of you out there are SO bored one night that you 
wouldn't mind doing this, I would greatly appreciate it:

Using an ungated, steady signal:

Sound of the unprocessed input signal (sine preferred)

Sound of shift down output with no change of shift frequency of 
the Shifter itself.

Sound of shift up output with no change of shift frequency of the 
Shifter itself.

Sound of the Mix output of the same.

All of the above again, this time with a steady gated signal (going 
trough a VCA controlled by a second or so decay only envelope 
(ramp out of an LFO would be perfect),

One more sample, from either down or up output, having the 
frewuncy of the shifter controlled with some sort of triangle LFO 
signal.

I undertsand this is an awful lot to ask. if any one obligies I would 
really appriecate it.

Thanks,

Peter

Peter,

I don't have access to the schematic, but I'll rattle a cage or two, 
and see what I can find.  Hey Bakis, do you have... ?

As for the audio testing, I'll do it.

Regards,
Kevin
