A-190-5 Polyphonic Midi-to-CV/Gate Interface

A-190-5 Polyphonic Midi-to-CV/Gate Interface

2011-02-11 by Sidney

Hello. I am very interested about the possibilities of the A-190-5 Polyphonic Midi-to-CV/Gate Interface. Does anybody knows if four oscillators controlled by one Midi channel, could be connected to a A-138 B mixer module and this output connected to a single filter and ADSR envelope to make a complete polyphonic system? Or would I need a filter and adsr and vca per voice?

Thanks,
Sidney.

beside the fact, that it is not very clear how the real A190-5 will look 
like.

You can use both combinations. The one you are describing is in fact how 
the Korg Monopoly works.

Hi Monroe. 

In fact I was looking for something similar to what Florian explained, working like a Korg Mono-Poly, because I could use the filters, VCA and ADSR modules from my system, just needing to add more oscillators in order to achieve a polyphonic system. 

Anyway, both ways explained by you and Florian would make a fantastic polyphonic system. 

But can two or more 111-5's filters or envelopes be synced in some way, so for example if I make a filter movement on one of the 111-5 will the others follow?

If you want to control the volume of each note independently you need one
VCA and one ADSR for each voice.  You can get away with one filter at the
end, but usually there is a filter in each voice.

I would recommend 4 A111-5 modules.  That's all you need.

It is not only the VCOs. You also need at least four VC-Switches, which 
are controlled by the individual Gates, and which switch the VCOs on and 
of (you sometimes want to play one or two notes only with a four voice 
synth ;-) ). How to create a Gate for the final VCF/VCA Envelopes is 
another thing. If you want it not retriggering, it is easy to achieve 
with an A186-1. But if you want retriggering you also need two A165.

The most direct way would be to control them from a common signal.  Use a
multiple to split the gate or filter modulation source.  However, if you
want to attack several notes independently, like how one plays a piano, then
you need one VCA and envelope for each VCO.  If you don't do this, then you
aren't playing "polyphony," it's actually called "homophony."

Re: A-190-5 Polyphonic Midi-to-CV/Gate Interface

2011-02-12 by Sidney

I wouldn't be playing polyphonic because the ADSR envelope would not be activated each time I touch a different note? Or maybe a new module similar to the A-143-2, with four inputs but only four knobs giving each voice the same envelope?   

Do you think that the A-190-5 Interface will be intended to control two or more 111-5 modules? If so, can their filters and envelopes be synced?

Sorry if I misunderstood something. I am trying to understand the multiple module function.

Re: [Doepfer_a100] Re: A-190-5 Polyphonic Midi-to-CV/Gate Interface

2011-02-12 by Monroe Eskew

Two basic musical properties are rhythm and pitch.  Polyphony is where there
are several voices with independent pitch and rhythm.  Homophony is where
several voices have independent pitch but identical rhythm.  Without
independent volume control for each oscillator you cannot do true polyphony,
for example sustain one note while another articulates many times.  For that
you'd need 1 vca to be open while another opens and closes as you play
different notes.

If you want the parameters on the filters and envelopes to have common
controls, you would probably want a few A176 CV sources, mult'ed out to
different VCFs and VCADSRs.  You'd still need to carefully tune the manual
controls on each one if you want it to sound the same on each voice.  If you
don't need common control but you want synced filters and envelopes, you
will just need to tune the one for each voice to the same values, and retune
each one if you want to change any parameter.

I hope I'm making sense...

Re: A-190-5 Polyphonic Midi-to-CV/Gate Interface

2011-02-13 by Sidney

Hi Monroe. Yes, you explained very clear. I thought that a single VCA could control all four voices if they were sent to a voltage mixer. The problem is not the number of modules per voice, but a way to make changes to the attack, decay, sustain and release of each adsr module and vca acting the same way in real time. Like a A-143-2 with four gate inputs but just one ADSR row and a single output. Don't know if what I imagined makes sense...

Anyway, hope the polyphonic interface come out soon. I will keep studying more. Thank you.

Re: [Doepfer_a100] Re: A-190-5 Polyphonic Midi-to-CV/Gate Interface

2011-02-13 by Monroe Eskew

I hope this is OK to say, but perhaps a different kind of synth would suit
you.  Polyphony can be achieved with a modular synthesizer, but it is
expensive and a bit of a pain to set up.  There are several polyphonic
analog keyboard synths with exactly the kind of control you are looking
for-- multiple full-fledged voices with common control over the parameters
such as ADSRs and filters for each voice.  They are engineered for real-time
polyphonic playing so it is already set up in the way it needs to be and
does not require the work that a modular does.  It also does not take
several huge cases to hold it together.  In my opinion if you want to play
polyphonic keyboards, this is a better route than modular which is better
suited to monophonic playing and sequencing, and then recording and layering
afterwords.

As for which kind of synth to get, the Dave Smith Instruments Prophet 08 and
Poly Evolver are still in production.  You can also look to something
vintage like Roland Juno 6.  Also the Alesis Andromeda was recently
discontinued but can still be found.  I personally use an Ensoniq ESQ-1 for
polyphonic performance which is a nice digital/analog hybrid and can be
found for cheap.

Best,
Monroe
