Hi group,

The manual of the A-190 MCVS states:

The gate output % and CV1 output & are automatically 
connected to the system bus of the A-100, so 
don't use patch cables to connect these, unless you 
have cut the links, or wish to connect to a module 
whose system bus isn't connected with the A-190's 
(have a look at the note on using more than one 
A-190). VCOs on the same system bus automatically 
receive CV1, and ADSRs automatically receive 
the gate signal. 

I however need a gate signal to trigger Reset In of the A-145 LFO. 
Can I patch the A-190 gate output to this Reset In? (I think I can, but am still a bit afraid to ruin something, so please forgive me my ignorant questions).

Thanks in advance,

Ton

The wording of this confused me for a while too...  If I understand correctly, it's fine to override the bus by plugging something into the *front* of a module to give it another gate or CV signal to pay attention to.

What you *mustn't* do is feed two different signals into the bus.  Feeding one into the bus, and another into the front of a module that usually pays attention to the bus, is fine.  It just ignores the bus as long as something's plugged into the front gate or CV input instead.

I could be wrong though, so check with someone else first. :)  But I've fed external signals into my A-110 VCOs, which are on the bus, without blowing them up yet, so the same probably applies to the A-145 LFO, A-140 ADSR and so on.

Hope that helps,
Zoe.

Thank you, Zoe.
I hope someone else can confirm this, else I just plug in the cable and hope for the best :-)

Kind regards,

Ton

Hello Zoë,

basically you are right, but some early modules (don't ask me which 
ones) did not use the switching function of the sockets. You had to 
decide with an jumber on the pcb, whether you want to use the socket 
input. Unfortunately if you enable the socket, then the signal is fed 
into the bus too.

Dieter might jump in here. As he should have the overview.

Only 3 modules are affected: A-110, A-111-1 and A-140 and as far as I know
everything is descibed in the corresponding user manuals:

A-110: CV1 is normalled to the bus (provided that the jumper next to the bus
connector is installed). As soon as a plug is inserted into the CV1 socket
the internal connection to the bus is interrupted.
A-111-1: If the jumper J1 is installed the bus CV is added (i.e. the socket
CV1 is not normalled but the CV signals of CV1, CV2 and the CV bus are
added)
A-140: gate is normalled to the bus (provided that the corresponding jumper
is installed). As soon as a plug is inserted into the gate socket the
internal connection to the bus is interrupted.
