Subject: [Doepfer_a100] Let me hear your bright new ideas for future Doepfer A100 modules!


hi Group,

some years ago, i had asked you to tell me new ides for forthcoming A100 modules and, after gathering all these ideas, i created many new polls...

so, its time that we do the same!

let me hear your, down to earth or crazy, ideas for future A100 modules!

i'l gather the best ideas (that are not covered from existing a100 modules) and i'll create new polls about these modules.

then, some of these may end up as new A100 modules...

digital, analogue and hybrid modules ideas, all count! 

(let's make the A100 even more 'out of this world"...)

also, this way, you may give food for thought to the whole modular community...

thanks,
best regards, :-)
Bakis.

I am with you..Have been whining about it here about 4 years ago.
I stopped whining after a few months and am now just eying the Analog
Systems RS30 & the RS35...
It will be Analogue systems I guess..



greetings,

Ernst

I'm on board, but...

Back in the days, when I was working with an engineer on my own  
modular, I remember him saying "pitch to voltage conversion is one the  
most difficult and complicated tasks to accomplish in an analog  
voltage-controlled world. It's one of the holy grails of modular  
synthesizer design."

But that was almost 30 years ago, so maybe now it's easier.

I still believe him, though. Otherwise p2v modules (and proper guitar  
synths) should be floating about in great[er] abundance, wouldn't it be?


Nevertheless, if Dieter says that's it a piece-of-cake, and cheap to  
build, then sure, I'm in.

Dieter did not want to go into it 4 years ago.But the module overview still
shows the A195...
Anyway.. the only way a Doepfer pitch to CV would be interesting now would
be its price I guess.

You might want to demo it first and see if it works for what you want it 
to. I have the RS 30, and it tracks bass frequencies fine but getting up 
into the midrange and higher with anything pure waveforms makes it just 
go crazy.

The new RS35 looks promising though..But thanks for the warning.

a pitch to cv interface module is in the planning stage for Doepfer already...
so no need for a poll about this.

Yes and no. If you have a clean rectangle its an eays job today: nothing but
a microcontroller that measures the period (e.g. the time difference between
two rising edges of the signal), calculates the corresponding voltage and
outputs the result by means of a DAC.

But the main problem is to obtain a clean rectangle from (nearly) any
monophonic audio signal no matter how dirty (e.g. during the attack phase of
a plugged string) it is. Even if the fundamental is missing a problem
occurs. The human ear (and brain) has no problem to detect the fundamental
(or pitch) even if only higher harmonics are present. With a simple module
(i.e. not a computer with a lot of calculation power and software like
Celemony) that's nearly impossible.

Best wishes
Dieter Doepfer

Exactly what I was thinking, Dieter.
You really need the power of something like Melodyne to pull this off  
properly.

We had quite a few engineers (in our DIY modular club, in the 70ties)  
trying to tackle the pitch to voltage dilemma, and they all gave up  
after a while. Sure, there were some simple modules working - nothing  
too critical - but as you say, if the fundamental got lost or was  
missing, your p2v got lost as well. I remember doing vc-panning and AM  
with my voice as input, which worked rather well, but anything more  
complicated or accurate... and, poofff... nothing.

Perhaps one day, when the power of modern CPU's is available in a 10- 
cent chip... One can only dream.

Hi

1. Programmable Quantizer.
Features: user definable scales with CV switchable memory locations 
to switch between e.g. D#m and Cmaj7, and A sus4. Analogue Systems 
make such a programmer, however, switching between memory locations 
is not CV controlled and you are limited to equal temperament.
I would like to be able to change the tuning scale between Equal 
Temperament, Just, Meantone, 19 equal temperament, 43 equal 
temperament etc.
It would be useful to be able to programme the module with exact 
voltages to make up unique user scales.
The usual functions such as transposition CV in, gate in, trigger out 
on pitch change, free run/trigger mode etc. would be included.

2. Voltage Multiplier/scaler would be handy i.e. a DC amplifier. It 
seems the A in VCA really stands for Attenuator! A simple module 
providing voltage input, gain multiplier range switch (x2 x5 x10), 
and a fine tuning range pot with positive and inverted voltage 
outputs could be packaged as a Dual Voltage Multiplier. If there's 
space maybe even a voltage offset pot could be included.

thanks
sean
