Dave Bradley asked [offlist]:

"Does the VC direction input just flip from clocking forward to
clocking backward, or does it retain the full VC stage selection of
the larger Miltons?"

No.  It's like the big Milton when in Keyboard VC mode.  Ground brings
it to stage 1, 8 or so volts brings it to stage 8 and everything
inbetween sends it to any of the six stages between those two.  It'll
be scaled exactly like the big Milt, so you could sync the direction
control the two to one VC source is you wished.

Hedi K asked:

"Could you explain us what are the precise uses of the VC Direction (LFO, Rdm voltage, ... to control the way the steps are played ?) and the Obediant Clock out on the Model 21C Mini Milton ?"

See above for the VC direction operation.  The Obedient clock passes the input clock signal out, but only then the sequencer is running.  f you halt the M21c, the obedient clock signals stop as well even though a clock may still be coming in.  This way you can sync your envelope to the Milton intelligently.


Norman Fay asked:

" I wonder if the 2 ADSR parts could be supplied behind a single 8u panel, for those of us who are somewhat obsessive over neatness etc."

No.  We had to make consessions, and this seemed like the logical way to go.  ne thing that interesting, why VC is available in the first place:  here are basically two types of ADSR circuits.  One requires 1 meg pots and is non-vc able, one uses 100K pots and is VC able.  The internals of the two circuis are completely different, but 90 out of 100 ADSR circuits use variations of these two.  In that I needed to order special pots for the ELFs that wer small enough under the faceplate to mount at a 90 degre angle without sitcking out the side of thenarrow faceplate, I didn't want to have ot order 1000 of the  megs just for the ADSRs.  So I used did a VC ADSR circuit derivative and was sitting when testing the prototype it hit me "hold the phone....we could add VC really easily by releasing a companion module" and that's how that happened.  WHen I laid that companion module faceplate out I realized there would be room for a Retrigger input, and it was a real win-win at that point.

Thanks Peter for your answers. I looked for some more informations about the VC 
Direction of the Milton sequencer and read this page:

http://www.buzzclick-music.com/async.html

Does the Mini Milton work in Async or in Sync mode when a voltage (LFO, ...) comes into 
the VC Direction input ?

Well, the second part of this question is : is it possible to run this sequencer from a 
voltage pulse (LFO or pulse/clock out of a Kenton Pro-2000) and at the same time to 
control the direction of the sequence with the VC Direction input ?

Many thanks if you can make it more clear !

Regards,

Hedi K.

In my system there are many more modulation sources with 0V to +5V 
range, than 0V to +8V. Even my envelopes are now at max +5V. To make 
things easier, would a jumper or trim pot be a good idea?

A quickie on the triple VCA - the upper two cells each have 2 CV
inputs, the lower has one, switchable between log and lin responses.
I'm presuming the 2 x CV ins on the upper 2 are both log, given that
the model 25's VCA is linear?   The, I dunno, logical thing for me
would be to have 3 identical VCAs, each having one log CV in and one
lin CV in, maybe?
