Hi,

curious to know how many of you have polyphonic modular set-ups, and
if so, how you tend to use them e.g. do all the voices share a filter?
Do they have individual envelopes? etc.


cheers,
os.

There are basically three approaches for polyphonic modulars with one 
common aspect. The common aspect is a polyphonic keyboard.

The three approaches are:
1.) The Korg PS-Series type: identical architecture for each voice. All 
parameters are voltage controlled so you can patch these control 
voltages. The approach is quite close to standard polyphonic 
synthesizers. Also the Nord Modular use this kind of polyphony.

2.) The Oberheim SEM type. You have several identical architectured 
voices, but individual parameter settings and patchpoints. You can use 
either the A111-5 or the Doepfer Quad-xxx modules for it.

3.) Large modular systems, where you have enough modules of each kind 
(sometimes not really identical) to patch several voices for a 
polyphonic synth.

My A100 can do a basic type-3 synth:
four VCOs mixed 2x110, 2x111
four VCFs 120, 122, 101-1, 105
four VCAs
four ADSR
Quad LFO

I also have a Korg MonoPoly, which I will extend with an 135-2 and some 
kind of eight VC-ADSRs. This one will be a mix of the type-1 and the type-2.

Hi,

  I use my modular (Doepfer/Analogue Systems mix plus a few other bits) as a duophonic with separate and identical architecture for each voice.  I use the Kenton Pro-2000 as a Midi-CV converter, with one channel set to the Lowest Note and one channel set to the Highest Note.  I have just redesigned my whole synth and got new modules to achieve this more effectively (I now have 6 RS95s and a pair of RS110 VCFs plus a few other filters).  It is very satisfying and I thoroughly recommend it.

Thanks for the responses.

Just gathering info in case there's anything I need to be aware of
when adding polyphonic support to Silent Way.

i've got a complete four voice architecture waiting for a polyphonic interface :(

dieter's new baby got moved to the end of the year, so that it could grow a display and a hole for a computer and get bigger (why why why, the original idea was so elegant?).

but i don't want to have to cart around another box/ac adaptor/long leads with me, so no kenton for me. a polyphonic cv/gate keyboard wold be even better, but let's stay realistic. one can but dream.

dieter, since the original a190-3 was a modified mcv 16, couldn't you offer that as a diy module? displays and usb connections will ruin my image :)

if the polyphonic thing takes off - and at dieter's excellent prices this seems not unlikely - then perhaps it will be worth developing a few quad modules for just that purpose:

- quad adsr with separate inputs and outputs but with adsr pots common to all four envelpoes. four vc-adsr's gets a tad expensive.
- ditto for a quad filter, although it's easy enough to control, say four multimode filters from one cv source. but again, very expensive and very big, although i suppose big is pretty inevitable if we're talking about a polyphonic modular.
- and a quad slew limiter, with whatever buffers are needed to make it usable :)

i can't see the new dark energy module being up to the job, there just aren't enough cv inputs, but the quad oscillator looks very interesting.

some tightrope walker whose name escapes me said, "life is on the wire, the rest is just waiting".

Don't forget a Quad VCA too. I think the "quad" line of modules should  
encompass the major functions needed for the "standard" voice. We have  
Quad LFO and EGs now the Quad VCA is controlled by one CV so not what  
I want yet - and Quad VCOs would be a challenge to fit nicely in a  
panel and be full featured but I am sure they would sell to many even  
it they were not destined to be in a polyphonic system. Especially if  
there were creative normalization implemented. Things like chained CV  
inputs that would allow all VCOs to run from CV jack 1 in nothing was  
plugged into 2,3 & 4 - or all VCAs in a quad module fed the same audio  
in only jack 1 is used (quad panner with a A-144 or A-143-9) or  
chained summed outputs to make a VC mixer. With creative normalizing  
used on inputs, outputs, and CV ins these modules can super flexible  
and easy to use for polyphonic and mono use.

Many customer suggested ro add a display and USB because of some reasons:

- With the rotary switch one is limited to 6 modes and there is no chance to
add more modes. With the display and up/down buttons more modes (even in the
future) will be possible and the display shows the selected mode.

- Without display there is no change to see the currently selected Midi
channel and reference note

- from our experience USB becomes more and more important because the user
do not want to add an additional USB-to-Midi box

We agree to these improvements and that's why the A-190-3 will be
redesigned.

We could offer the MTV16 board with the existing firmware "as it is". But
there will be no updates or bug fixes as I think that most user will prefer
the module with the display and USB interface.

that all reminds me a bit to my PMS (polyphonic modular system) that was
available in the eighties. The system was based on quad modules (quad VCO,
quad VCF, quad VCA, quad VCADSR and so on).

We will offer some more quad modules in the future. The next modules will be
the quad VCLFO and a low cost quad VCA. We also think about a quad slew VC
limiter with separate controls for rise and fall time. And even a quad
VCADSR is on our to-do list.

totally agree with the LCD discplay on the A190-3 module.
i think it would be essential for easy navigation and use.

as the A190 wasn't exactly very easy to use...

splendid!

quad vcdsr: all four units' settings normalled to the first?

quad vclfo: traumhaft! if you can find room for a reset input, it will be the perfect module and i'll buy as many as you can make :)

> quad vclfo: traumhaft! if you can find room for a reset input, it will be the perfect module and i'll buy as many as you can make :)


i second that, reset inputs on the quad vclfo would be
great, if not to say essential.

best wishes

ingo

Yep, reset inputs and you can take my credit card number ;-)
