voyager and dotcom

Hi

Does anybody on here have any experience of using their voyager with a synthesizers.com modular? I’ve successfully driven the dotcom from the voyager via the vx-351, but today I tried driving the voyager from the dotcom and got some surprising results.

I connected the qkb15s keyboard controller (1v/oct) to the pitch and gate inputs on the voyager, but found that the voyager was tracking less than an octave per volt. Now I know that the voyager pitch input is .935v/oct, so I would have expected it to track more than an octave per volt. I was anticipating having to put the qkb15s cv through an attenuator to bring it down to .935, but if anything it needs boosting. The qkb15s is definitely putting out 1v/oct as I checked it with a volt meter. Why would my voyager be behaving like this?

Any thoughts or ideas gratefully accepted.

Thanks

Simon

I own a Q119 sequencer and absolutely love it with the Voyager.

Usually when controlling pitch on the Voyager with the q119, I send it to a CP-251 LAG processor and then to the attenuator/inverter.

VERY fun.

I've gotten quite good results.

Extremely happy.

Hey Analoghaze....

So you've been able to get some portamento effects when using the Voyager with the Q119, via the CP-251? I have the same setup, and was wondering what to do to get some glide to work when I'm sequencing the Voyager.

Thanks for your help.

It's really simple. Take a bank from the q119, send it to the lag processor, and then to the inverters, and to the pitch in on the Voyager. Use the gate out on the q119 to trigger the envelopes on the Voyager.
The LAG works perfect. I even do this with the 107s.

Thanks for the info. Is it more controllable than just using the glide on the Q119? I've tried using that, but every note ends up having the same amount of glide time, which makes it not so usable.

Well, the glide is only avaible on the master out on the q119, so it adds options there. The CP-251 also has a knob for raise and fall time, do it is definately more adjustable.

It can be fun.

Thanks again for the info. That was always one of the sticking points for me in using the Q119 with the Voyager, because portamento plays a big role in some of my parts.

Hi Simon,
i had the same Problems. My first experience was that the normal patch-kabel ist not good for routing the pitch-cv from the voyagr to the dotcom. I took two 6,3mm Jacks and connected them with a simple high-voltage - kabel (the same that you find on your toaster or Radio). This has a much less resistor and MAYBE work great.
When i used normal patch-kabel for routing the pitch cv i first jacked it into a dotcom signal-prozessor, here you can adjust the voltage - with clean ears it will be no problem to adjust the cv, so that it fits from the lowest to the highest key.
The most "clean"method to couple the voyager to the dotcom ist by using the dotcom midi-interface....but that, of course, ist not that, what "modular friends" like to have...

I asked EMC in germany about the Problem, but they didn´t have heard about that before - so I´m glad to read, that I´m not alone.
Best regards
Martin

Hi Martin,
I get similar results.
Using a digital VOM and a Roland tuner, I get
the following input to the pitch CV in on a Voyager PE:
0 V no change
+1.028 up one octave
+2.05 up two octaves
+3.08 up three ovtaves
+4.11 up four octaves
-1.028 down one octave
-2.05 down two octaves
My Voyager does not have 1v/oct. scale on the pitch CV input.
Very noticable using the Q960 with a quantizer, or any of my 1v/oct. keyboards, my Voyager plays flat up the scales.
Not sure if there is a fix for this, other than to just use MIDI?

Thanks for all the replies. At least I'm not alone in this! I'll have a go with using different cable and see if this helps.

Has there been any change to the v/oct thingie of the Voyager? Is it still 0.935V/oct??

Just today I tried my Old School with the Q960 sequencers of my dotcom
for the first time. Other than that the pitch is not exactly the same as my
dotcom VCO's, it behaves perfectly. Now, what that particular thing is
about the Moog not tracking exactly 1 V/Oct is a bit beyond me. AFAIK
almost every analog synth of today is exactly 1 V/Oct. A long as I run the
Voyager alone it's OK, but not when I add some dotcom VCO's. But
fortunately there are trimmers on the analog board of the Voyager to
calibrate the tracking yourself, or let a technician do it.

Cheers,
