Doepfer

Hello, this is my first post and am looking for some help in connecting the common bus for 2 seperate systems.
The first is the basic case 2 containing the following modules
A110 x2 A145
A114    A146
A115    A160
A116    A161
A138    A180
A120    A170
A130    A138
A131    A170
A190    A140 x2
A118
The second is, or will be in the CL9case (for future expansion)
Modules proposed
A111-5, A150, A154, A155, A156 & A190-3
I have 2 A185 modules and wish to make use of these to be able to connect the two systems. I am finding it difficult to understand what jumpers or connections need to be made to achieve a safe joining of the two systems. I also wish to be able to use them as seperate units from time to time.
This is my first venture into modular synthesis and I am caught hook line and sinker as the saying goes.
Any help would be very much appreciated.

Bare in mind Anthony that only the A-140,A-110 and A-111 will take the gate and cv from the bus provided byA-190. So far this is what I was able to hook up. I think it is possible to extract the bus signals (cv,gate)from your basic case but it requires some soldering,drilling etc...
What I do is take the cv1 and gate from A-190 and patch it to my other OSC or ADSR that lives in other cases.The modular advantage.

Thanks Rudy, I am not at all keen on drilling and soldering so I hope to take full advantage of the modular system. As I mentioned I am very new to this so when I recieve all my modules I will put them together as a system and then I will be able to see, with the guidance of good people like yourself, just what to patch to what. I think I understand what you are telling me but until I can actually physically do it I shall hold back.
Look forward to further input.
Thanks

I believe you simply need an A-185-1 module in both systems, but I haven't actually tried this, so check with someone else first.  As Rudy points out, though, this will only affect the oscillators and envelope generators, so you may not even need to hook up the two cases anyway.  (For example, I have sound sources on my first row and envelope generators on my second, while the third row is just filters and effects, so I don't need to wire up the third row to the bus at all, even though it's in the same case.)

All the best,
Zoë.

Zoe, thanks to you too, I have had info from Dieter Doepfer who says that maybe the easiest way is to patch from the front as you intimate and Rudy suggested. I shall definitely try this when I have got things together. I have to repeat I am very new to this so please be patient with me (I'm 63 by the way, so a little slow).
kind regards
Anthony

I think we will have to add some notes concerning this issue to the technical information of the A-100. Especially for first-time users the CV/Gate idea via the bus is not obvious. Here some remarks:

- The main function of the bus is the power supply of the A-100 modules (-12V, GND, +12V and additional +5V for a few modules)
- in addition a CV and Gate line are available
- some modules can pick-up the CV signal (e.g. A-110, A-111-1, A-111-5, A-143-4) from the bus depending on the jumper setting on the module
- some modules can pick-up the gate CV signal (e.g. A-140) from the bus depending on the jumper setting on the module
- but most of the A-100 modules have no access to the CV or Gate signal of the bus
- other modules may work as transmitter for the CV signal to the bus (e.g. A-190-x, A-185-x) depending on the jumper setting on the module
- other modules may work as transmitter for the gate signal to the bus (e.g. A-190-x, A-185-1, A-164-1) depending on the jumper setting on the module
- pay attention that only ONE transmitter for CV and ONE transmitter for gate are allowed (otherwise modules may be damaged)
- using the internal CV and Gate lines of the bus is optional (one may also patch the required connections via the sockets at the front panels)
- but using the internal CV and Gate lines may simplify the patching at the front panels (e.g. if several VCOs have to be controlled by the same CV, in this case the A-185-2 is recommended as CV transmitter to the bus, the A-185-2 allows also common octave switching and common frequency modulation of all VCOs as well as CV summing, e.g. from a sequencer and CV keyboard or Midi-to-CV interface)
- both the CV and the Gate line can be interrupted in the middle of the bus board to establish two different CV/Gate areas. For this the corresponding jumper in the middle of the bus board has to be removed.
- A special CV/Gate bus connection cable A-100BC is available. This cable can be used to connect the CV and/or Gate lines of two different bus boards. To connect the two boards the same pin headers of the two bus boards may be used that also interrupt the CV and/or Gate lines. But it is also possible to connect the corresponding pins (Gate and/or CV) of other unused bus connectors (i.e. one of the 14 16 pin connectors)

Hope this helps

Best wishes
Dieter Doepfer

This should read like
"some modules can pick-up the gate signal (e.g. A-140)"
The 140 does not use any CV

I don't feed gate or CV from any module to the bus. Instead I added a 
A-185-1 "Bus Access" to each row, so I can wire manually any source to 
the bus.

I have 4 Portable 6U Doepfer cases and A-185 modules in three of them. I have modified a few modules to use the bus by making some power ribbon cables with the CV and Gate lines broken out and soldered to the normalizing ins of some modules (as shown on the Doepfer DIY page), Most of the time I use the A-185 as a buffered multiple though - taking one CV and making two or taking one gate and making two. They are vary useful for that. Otherwise just buy a bunch of long patch cords. A couple of my cases can be stand alone - they have a typical "voice" laid out in them but after a while I gave up on arranging the modules in a logical manner. Now they go where they fit. With long patch cords it really doesn't matter - I connect to a module wherever it is in my system. Sometimes the odd placement of a module spawns a new use in a patch "because it is there" and near. The Bus Access module is not needed to connect systems but it is useful if you have a A-190, and a couple of A-110s and A-140s in one case. Or if you mod your other modules to accept bus signals (and if they have available normalized jacks at their CV/Gate inputs). Also remember and heed the warning about only ONE CV/Gate source to the bus at a time.
