I bought a 2nd hand vx-351 & cp-251 today,i paid a fair price and it came with all the coloured patch leads etc
however…
it comes with a chip/connector,the chap who sold it me said the chip go`s inside the voyager when i use the vx-351,.and it should be removed when i dont use the vx-351.
this to me is a PITA,. is this correct ? i need to take of the backplate from my voyager everytime i want to use the vx-351 ?!?
If so thats a terrible design mistake.,
do i need to use this chip ?
Darren.
No, you don’t have to remove it when not using the VX351. I don’t, and it works just fine.
thanks Mark,.
that helps mate cheers.
OT: don’t know if you’re using a RME unit or a KB, but if you have the rackmount version, the chip isn’t neccesary.
cheers fella,its the keyboard version 
On an update of this,
i got the connector chip in tonite and had a mess around,.i got a couple of basic patches going as shown in the voyager manual - but to be honest i didnt do much,. nor did the vx-351 lol
i had the filter modulating a little,and at one point i got a great star wars type zap sound ,. but i couldnt do anything else as im terrified of connecting an out to an out or an in to an in and burning something in my moog out, as for the cp-251 ,well it does nothing,it lights up when connected to the wallwart but i couldnt hear it doing anything,.
and overall after an hour or so i had the vx-351 going,. woo woo woo woo lol
is there any online examples for patches that show what to connect to what etc so i can experiment more ?
thanks for any help in advance
darren.
Darren-
There is only “one” “no-no”: do not plug more than one voltage source into the multiple; for this, use the 4-input mixer. Any other patch you can think of is fine, as long as it doesn’t involve high voltage.
The CP-251 is not a sound source; it is a Control Voltage Processor. The only way you will get sound out of it is if you plug the noise output into an amplifier + speaker.
You did look at the manual for examples, didn’t you? If you don’t have a hard copy, you can find one on the Moog site under the product listing. Btw, the VX-351 manual is at the back of the Voyager manual.
Have fun!
hi thanks for the info latigid on,
when you say multiple do you mean the area on the vx-351 where it says “multi” and there are 4 jack sockets ?
or do you mean on the cp-251 where it says “four-way multiple” ? and do you mean like no more than 1 out going into the multile ?
with thanks.
darren.
Hey, yep they’re both the same thing: 4-way multiples.
One interesting patch would involve combining a few different CVs (e.g. two LFOs with different waveforms). If you plugged both LFOs into the multiple, you would risk damaging your equipment. Instead, you would mix the waves with the 4-input mixer.
Hope this helps.
Look here for a few examples & ideas:
