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
