Rejoice!, I just received word from Linda that they are soon to release a modification to address the lack of filter glide.
…There is also a modification to the analog board to fix filter glide issues. If you are interested in that, please contact our Tech Support Department.
Best regards,
Linda

I have asked for the details from Tech Support. I will post the mod once I get it.
I can’t wait…

Thank God! I will definitely get that before the V3 board. Thanks for the good news.
forgive my lack of knowledge, but what exactly is filter glide?
can you give me an example?
or just pls describe it…
thanks
Hello,
The glide function in the left-hand controller section routes the keyboard
cv thru a slew limiter to create a continuous change in pitch on the keyboard. On the Model D, the slew limiter was also assigned to the filter,
so that the pitch and filter functions would glide simultaneously.
Many (if not most) feel that the V’ger should be set up to most closely model the Mini D’s functioning.
Although it may be implemented in a bare bones fashion, it will be interesting to see if the filter glide function is made switchable,
along with a choice of linear/exponential tracking modes.

The mod to add filter glide consists of lifting the leg of a resistor from the analog board and attaching a wire from the lifted end and routing the wire somewhere else on the analog board according to Moogmusic, however I have not yet received specifics. This means that unless you have Moogmusic do the mod (which BTW was originally proposed) you will most likely void the warranty. When the details are released do the mod at your own risk!! [There ends my disclaimer]
Therefore the glide characteristics of the filter will mirror the Pitch CV glide. So the implementation should be similiar to the model D.

Gee, that’s strange because I asked Moog about a month ago about making a customization for the filter-glide and they said that they don’t have the manpower to do such a thing.
I don’t know who you talked to, but I twisted their arm and helped them design that filter glide fix back in 2003 when I brought my Voyager down there for a tune up. And the fix is indeed as bosonob describes. And no I can’t share the details because of warranty issues. And yes the filter glide fix sounds great.
MC- What about an aftertouch fix, is that possible either as a software or a hardware mod?
I’ve been in touch with them about the AT, they’re aware of it and the best solution may be hardware. It’s a quirk related to the fatar keyboard AT element. No info when a fix will be available though, let them get the LP production behind them.
Is the glide mod really necessary though, and would it affect any patches set up for the system as-is?
I suppose the glide fix will affect all patches. I am not an EE though so I can’t tell for sure.
Are all Voyagers now shipping with glide and aftertouch fixed? I am very happy. 
Hello,
The glide mod gives the Vger a character a bit closer to the Minimoog D.
Also, it does affect all patches that currently have the glide function selected. You can check out the difference if you have a VX/CP-251 combo.
The difference is enough that any patches that use just oscillator slewing would need to be re-programmed slightly (filter freq and kb tracking), because the addition of slewed votage to the filter makes them sound noticeably different.
Glide with and without slewing to filter are both useful in that if you have the Vger set up for simulations of Moog and non-Moog synths that use pitch slewing, but w/o filter glide, being able to disengage the filter glide keeps them authentic.
One possible solution would be to make the function selectable in the software, so that the function’s status can be recalled with the patch.
Its not a complicated matter to make it switchable from the glide selector
switch, but having it selectable as a programmable function from the
parameter menu would be a little more elegant.
By having the filter glide function selectable from software (w/no filter glide as the default state), any patches w/pitch slewing previously programmed on Vger will sound the same and not require re-tweaking, and all new patches in which the user wants a character closer to the model D can have the function activated fron the parameter menu.
Rudi, I know things are busy, with the LP release, but how much trouble would this be to implement in the software?

Lawrence
Software selection is not possible as the keyboard CV to the filter comes from the same slew generator used for oscillator keyboard CV.
Hello,
Correct, but I’m not talking about creating a software-based slew function here. The glide rate and on/off state are already saved in patch memory.
If you wanted all three states, i.e. glide off, just oscillator glide on (as it is now), and osc glide w/filter glide, you’d normally have to change the
rocker to a three position switch to accomodate the third state. I’m simply referring to having the filter glide turned on/off from the menu,
instead of having to swap the glide switch to one that has a third position.
This would provide selection of the new filter glide state, plus all patches already created for Vger, using just oscillator glide, would remain unaffected.
Also, what is the cutoff point (serial number) for SE’s that have only two keyboard cables?
Regards,
Lawrence
What might be really useful is if some kind forum member would post an audio example of the difference.
Any takers?
Can you please elaborate on how the VX351/CP251 combo is utilized to achieve this end???
Hello,
You take the Vger’s keyboard cv from the VX-351, patch it to the lag processor input on the Mooger CP-251, then connect the lag processor output to the filter cv in on top edge of Vger panel.
Even though you have it now patched, the speed of the filter glide has to be calibrated to be the same as the slewed signal (internally) routed to the oscillators.
One way of approximating this is to crank the resonance up enough to self- oscillate, increase keyboard tracking to the point that the filter sine wave pitch tracks with main audio oscillator (Osc1), but keep the main audio oscillator at the same approximate volume as the sine wave the filter is producing, activate the glide function in Vger’s LH controller section and set glide rate to about half (or any rate that is easiest for you to calibrate the parameter).
You can now adjust the lag processor’s rise and fall time so that the glide
will track at about the same rate and range as the slewed oscillator signal.
When they’re closely matched to about the same rate, you can then decrease the resonance and use the filter as normal.
The filter frequency should now slew at the same rate (or about the same)
as the oscillator glide.
I say “about the same” because when its done by ear, using an external lag processor, its an approximation and not exact as when the oscillators and filter share the same lag ckt.
Regards,
Lawrence
Thank you very much. I’m gonna try that out this weekend.
For those that have had the Filter Glide fix done, are there any regrets? I was planning to get this done (actually, my MMV is at the factory now!) but the idea of screwing up many of the presets worries me a little. If they are easy to tweak back to normal, no big deal.
I’m curious if I could install a switch to turn the Filter Glide on and off. From the few details posted, it sounds possible. I guess I’d have to see what was done to know for sure.
Thanks!

As my SE is out of warranty, Amos has just posted me the mod… looks simple enough but here’s a question for you.
Given that this functionalty can’t be software selected, could I not put in a toggle switch?
I could route a switch somewhere were it is discreet… just wanted to know whether you thought having the option NOT to have the filter glide was worth making a modification?
