There are still some additions/changes to be made. For me the most important
thing is the missing rotary octave switch. In the prototype we have a wide
range tuning knob and a fine tune knob available. From my point of view it's
too complicated to use the tuning knob to adjust the frequency to another
octave. Maybe I'm a bit spoiled by the A-110 and A-111-1 in this regard but
for me it's a must have. Unfortunately this addition affects all pc boards
of the module and the front panel layout and requires a total redesign.

Hi Dieter

I bought the Roland System 100 from Bakis some month ago, which has a 
VCO without octave switch, but a wide range potentiometer and a fine 
tune. I really appreciate this feature for a lot of sounds and find it 
extremely more useful than a 5- or 6-octave switch. Nevertheless I 
sometimes miss the possibility to switch one ocate up or down. So my 
suggestion is:
- wide range pot 10 octaves
- fine tune 10 semitones
- on-off-on toggle switch with one octave up, normal, one octave down.

while florians idea is good, i still like the
rotary octave switch better.

I think a good compromise would be a jumper for the tune potentiometer that
defines the tuning range: ~ +/- 1/2 octave (for customers who prefer the
octave switches) or ~ +/-5 octaves or even more (for customers who prefer a
wide range for the tune control).

That is ok, but where to place the rotary switch for multiple octave 
switching on the frontpanel?

That's indeed our main problem ...

I have been giving it a thought the widerange tuning might be very cool. But
the rotaryswitch has a lot of uses too.Why then use a jumper? A switch on
the front would be even nicer then.

just my thought...

This is why I suggested the on/off/on switch, which usually can be 
placed between two potentiometers.

The other options is to go more modular: offer only some basic CV in-s 
at the core module and offer additionally an extended CV mixer, with 
multiple octave switching, coarse, fine, micro tune, and several 
modulation inputs with mod-amount potentiometers for log an lin modulation.

(I dont want to be nasty, but I suggested this module quite often - may 
be I should do a small business for modules with underrated sales 
chances ;-)))) )

Florian,

I would not recommend that :-)

E.g. the mix expander module A-138x is the poorest selling module ever ! The
module is available since early 2007 and we sold less than 25 so far (less
than 2 per month).

Why not a combo of both - a multi-octave select switch wit it's last  
position turning the tuning knob into a wide range tuning knob.  The  
best of both worlds.

it would be better to use a combination of a simple module of octave knob and precision 
adder.

Actually that would be a better idea. Then the cost of the main VCO  
could be cheaper to those who don't need these options. This module  
of course would work for VCFs also. For me the module would be  
perfect if it had an Octave select switch, a fine tune knob, a CV in  
(or two that sum) and multiple outs (4 would be nice). It would be  
used as a master VCO controller module (didn't Moogs have a master  
VCO module of some type?). One or two CV in be summed and could  
control any combination of 4 VCO/VCFs without loading and have a  
master transpose too. It would work great controlling multiple band- 
pass filters too. Basically it would be a A-185-2 with a octave  
select replacing the toggles and the attenuator becoming a voltage  
source. The A-185-2 is almost perfect.

I just purchased my first oscillator without a wide range continuous 
tuning knob. (It has an octace switch and a fine tune of +/-6 
semitones). I find this arrangement frustrating and unsuitable for my 
needs. In my opinion Plan B M15 has it right: Continuous Coarse tuning 
and Fine tuning. And importantly the fine tuning is only +/-1 semitone, 
which makes tuning actually precise and easy.

Of course, if there is an *additional* octave switch, I don't mind, 
except that it takes some space. I would still propably rather use 
something like 185-2.
