Happy Birthday!!! I’m late… sorry…

Midi Guitar 3 is turning into a Hexaphonic Guitar Toolkit. Just got started, but I’ve got a setup with two chains doing hexaphonic audio processing and one chain for a synth vst. It is quite powerful and the re-tuning function is awesome. I’m using in conjunction with Bluecat Audio re-guitar to shape the sound of the GK hex input as well as Helix Native and other plugins. There is nothing like it out there.
One thing, though. I want to blend the VG-800 sounds, such as the VIO instrument with my two MG3 hex audio chains and the synth vst chain. The VG-800 sound seems to come through both of the hex audio chains. Is there a possibility of just going straight to master with the externally processed audio, or have the ability to add a chain for just the externally processed audio? Am I correct that the hex audio carries along with it the audio from inputs 1 and 2?

You can mix sounds from the VG-800 (USB1+2) with synth sounds generated from the VG-800’s USB 3 to 7 signals.
To do this, you can use the Audio Device module by selecting the VG-800 as the audio source.
Here after is an example:

Yeah, you would think that is the way it should work. But, if I add a separate audio device chain, I’m getting 1 & 2 on the hex chains as well as the separate audio device chain. It’s feeding 1 & 2 to the hex chains. I believe this would be considered a bug?
No. MG3 is able to select the right channels for the hex inputs, USB channels 3 to 8 from the VG-800.
In this case, you even do not need to select an Audio module, MG3 select the USB inputs 1 from the VG-800 as the audio input.
FYI, I’ve had the same experience and I’ve reported it to JO.

As you can see in this screenshot, on the first row the VG-800 you have the output of the VG-800, and in the same time, the 6 signals from VG-800 are selected for the HEX inputs of the MG3.
As @lpspecial indicated the issue exists. You can sort of work around it by deactivating channel 1/2 audio pass through on the device…
In my report I wrote: “The string retuning module is allowing audio from USB audio Ch. 1 or 2 (when the Audio Device is active in another chain) to join the hex signals on 3-8.”
But, I think it’s actually any hex module. Please correct me if I’m wrong.

I admit I don’t really understand the problem…
For me, everything is working properly. The Hex module is picking up the correct signals, and I can access output 1 of the VG-800 on the MG3 audio channel. In fact, I have the impression that only output 1 of the VG-800 is being sent to channel 1 of the MG3Hex, in mono.
What are the malfunctions you’re noticing?
In this dual path setup (both retuned hex feeds: A to Amp Sim/B to Synth) the Ch. 1/2 audio (main mix) from the SY-1000 is being processed by the first MG3 chain. It’s very clear to hear because I’m using standard tunings on the SY-1000 main path.
The Audio Device module does not need to be present for this to occur.
Notably, I am not using the SY-1000 as the audio out monitor in MG3 Hex, so it is certainly not a routing mistake on my part. However, deactivating INST 1 in the SY-1000 solves the problem – but that means you lose your lovely SY-1000 tones 
It’s difficult for me to understand what’s going on in this type of setup because I don’t have a SY-1000.
Does the SY-1000 have 10 external USB signals like the VG-800?
However, I think that only channel 1 of the SY-1000 is sent to the chain 1 of the MG3Hex.
As for the rest, only Ole can tell us, for this SY-1000, which USB signals he selects by default for the implementation of the Hex module.
-Ch 1-2 carry a selectable signal (various options);
-Ch 3-8 carry dry per-string audio.
It’s not about the SY-1000. It’s just that audio from 1-2 is being allowed in along with/alongside Ch 3-8 on the hex audio chain where it’s not useful.
I’m using it too. It’s subtle but helpful to tame the dry string tone.

Another option was Ascend VPU v1.1.2 from Cycfi Research:
Unfortunately, the link is dead. I’ve contacted the developer to see if a new link will be provided. You can also get good results with Sweetspot.
@lpspecial - I’m a bit confused about this. What’s the simplest patch I can make that reproduce this unwanted chan1&2 behaviour? Can you drop a simple patch here?
Ascend VPU 1.1.1 is still available: Ascend VPU v1.1.1 – Cycfi Research

@Lpspecial I tried your patch on the VG-800 and, indeed, I get the same result as you: we can clearly hear the VG-800 outputs 1 & 2 in addition to the VG-800 string outputs!
With this setup, the chains with Audio/MIDI conversion in Hex mode are functional, but we can clearly hear the very attenuated outputs 1 & 2 in addition to the synth signal…
There is definitely a bug there.

1.1.1 is an expired evaluation version. I just got notified that an upgrade is in the works. No timeline on when this will happen, but Joel of Cycfi will post an announcement when it is ready. Come to think of it, it is really not useful for using within Midi Guitar 3 because it requires 6 individual instances, one for each string.
