Doepfer

Dear members,

I'm back from NAMM. My Yahoo account has stopped again working during my
absence. If there were important questions during this time that have not
been answered please send them to me again. I'm not sure if I have time to
see through all messages of the group during this time.

NAMM visitors were very interested in the new modules and the CV/Gate
keyboard. There were also some suggestions primarily for the A-137-2 Wave
Multiplier II and the A-189-1 Bit Modifier:

A-189-1:
voltage control of Mode (instead of the 16-position rotary switch)
ext. clock input for the sample rate (instead of the voltage controlled
sample rate)
additional VCA at the signal input to modulate the incoming signal before
it's processed by the bit modifier

A-137-2:
output mixer (original + 4 additionally generated signals, in the prototype
all signals are mixed with the same level, no level controls)
offset control for the phase shifts (in the prototype the initial phase
shift is fixed to 90 degrees)
single outputs for sawtooth and rectangles (i.e. 8 separate outputs), maybe
as an additional 4 HP module that has to be connected to the main module

Tell me what you think and maybe we will start some polls before we release
the new modules.

For the CV/Gate keyboard the type of the transpose function has been
discussed: octave (as it is now) or semitone, maybe we will make it
adjustable in the config mode (in this mode basic functions like midi
channel, gate polarity, keybed length and some others are adjusted)

For the other modules (A-138e Quad Triple Crossfader/Mixer/Polarizer,
A-106-6 XP Filter/Filter Pool, A-132-3 Dual lin/exp VCA, A-134-2 Dual VC
Crossfader) no or only a few suggestions were made.

Provided that no changes are made all new modules will available about April
2008. If a module has to be redesigned there will be a delay of about 1-2
months depending on the extent of the modifications.

The CV/Gate keyboard will be manufactured in February and available about
end of February 2008.

Best wishes
Dieter Doepfer

I'd not say "instead of voltage control", but there should be an 
additional insert point.

If it is not cost relevant this would be a nice addendum.

A-189-1:
I would like to have voltage control of samplerate and an insert for
an outboard clock source. The extra VCA at the input could be ok, but
not essential.

A-137-2:
To me it seems best to make an expantion module for this, so you can
have the cheap version and if you want more control get the expander
module.

Both these modules demo audio files sound great, I must have them.

having heard the demos of this thing i'd say add anything that won't
hold up development for more than a day - can't wait to order one of
these :)

Hi Dieter,

that's a clear "yes" from me to the a137 and a189 suggestions.

actually, yes, an internal PLUS an external clock option would be  
best for the AD/DA. And: the internal clock should have an "insert"  
design, where you have the clock available at an output, normalled to  
the external clock input socket. this way you could insert a logic  
module (like an "and") fed by the internal clock and an external  
one....in the simplest usage this would enable a "sample and hold"  
using a gate for external clock: sampling at internal frq while  
gate=on and holding last value while gate=off.
or of course two audio rate clock signals AND-ed would  probably  
cause very interesting destruction of the sampled input (especially  
interesting with simple input signals).

Hi Florian,

I'm not sure if this is possible and have to discuss it with Christian. So
far the sample rate is software generated and the voltage applied to one of
the ADC inputs is used to define the sample rate. This is totally different
(hard/software) from an external clock. Maybe we can divide the software
into two different independent tasks: one for the VCO with the clock output
at a separate pin and another task for the actual bit modifier software. The
first task has to output the clock at one of pins of the microcontroller.
This pin is normalled via a jack socket to another pin that is used as clock
input. This socket can then be used as an input for the external clock too.
But I'm not sure if this will work (i.e. if the two software task do not
interfere with each other). Christian will have to decide if this could
work.

Another solution would be an additional switch that switches between CV mode
and clocked mode (or 8 CV and 8 clock modes). The socket could be connected
to two pins simultaneously (ADC input and a fast clock input) and the
software decides depending on the switch position if the ADC input (CV mode)
or clock input (clocked mode) is used.

The additional VCA will be included only if it can be realized by software
(i.e. by a simple multiplication). The microcontroller we use has a
multiplication instruction that requires only one cycle.

Dieter

Hi Denis,

I think we should start a poll as we have - as usual - too many different
opinions (I discovered this already during NAMM): from "leave it as it is
and manufacture it yesterday" up to "add all suggested options even if it
will take a few more weeks or months". I'll prepare a list with all
suggested options and the corresponding approx. additional charges and
development/production delay.

Best wishes
Dieter

i would buy it immediatley if it comes out as it is for the mentioned price of 80 Euro

but i have to admit that the suggested features are intresting!

For the existing version the retail price of the A-189-1 will be between
about Euro 70 and 80 (in any case 80 Euro or less) and between about Euro 50
and 60 for the A-137-2. With additional functions we will probably go beyond
Euro 100, mainly because of the larger panels and the additional sockets and
controls.

Dieter Doepfer

just my 2 cents - a bigger panel for the 189-1 would hesitate me from
buying right now  - i'm running out of rackspace again :(

hello Dieter,

of course!
when you have all the poll options ready and clear
please send them to me to make a new poll,

best regards,   :-)

Hello Bakis,

thank you. I'll get in touch with you as soon as I have the list of possible
mods (and related surcharges and production delays) ready.
