Yes, sorry, i don't know where the Signature settings are.

It's a 2017 iMac 3.5ghz running OSX Sierra with 24gb RAM. I've got an old MOTU 8 Pre that i've connected up and still has the same issue of inputs for stereo pairs being offset by 1.

Have done a couple of screenshots to show what I mean. Talkback, which is 1 channel, is taking up the left side of a stereo pair and offsetting all the concurrent pairs by 1.

I guess the easiest thing would be to disable the TalkBack channel. I have no need for it as I'm Synth based and don't record Vocals/Musicians. If there was a button underneath "TalkBack" that disables it, that would change the amount of inputs to an even number.

I suppose if you were daisy chaining more than one Quantum but needed only stereo pairs, not mono, then this wouls also be an issue for some? I only use Line Ins and don't use the Mic Pre's (XLR) at all...Just stereo pairs from a PatchBay.

Having looked around, there doesn't seem to be many odd numbered audio interfaces out there, i mean with an odd number of inputs, as the Quantum is (27)...Most have an even number that I can find.

Basically I have a lot of Synths, so I use the 8 Line Ins of the Quantum coming from a Patchbay and I use 2 Behringer ADA8200 over ADAT, 1 is for Send/Returns of 4 FX Pedals and the other, is used for 4 Synths in Stereo.

So when setting up in Logic, stereo pairs are 1-2, 3-4, 5-6...and so on, up until 25-26 and then it goes 27 - 28...27 is the TalkBack and 28 is the left channel of a Synth...next pair is 29 - 30, but is the right channel of 1 Synth and left channel of another, respectively...I can't seem to get around it.

I've thought, if I can find a single channel audio interface, that is just mono and use it as an aggregate device as well (so there would be 3 in total) then I could have 1 to 27 being the Quantum, 28 being the mono device and 29 onwards, the MOTU...

Would be easier though if Talkback could be disables or is duplicated to make channel 28...

Looks like you are working on it, but you can also create a support ticket.

Well, I got a IK Guitar Rig HD, but sadly shows up as 2 inputs. As I said before, the Talkback channel needs to have an option to disable it. I thought about getting a Quantum 2 to add to my Quantum but it would still be the same problem with that.

Needs a fix.

Can you please, in as precise and few words re-explain the issue to put it in a form submitable to a developer?

I'm not sure how to break it down further, only that I use the interface for Stereo Pairs.

Intaed of thinking of the individual Analogue inputs and individual ADAT inputs, see them as Stereo Pairs.

The analogue Inputs are Stereo Pairs 1-2, 3-4, 5-6, 7-8 (With the odd number being the left channel and the even number being the right channel of a stereo pair.

The ADAT inputs continue the Stereo Pairs as 9-10, 11-12...all the way through to the final pair which is 25-26.

All of that above works fine and shows up in Logic Pro.

The problem happens, when I want to add an Aggregate device to increase the number of inputs, to go beyond what I can add with the Quantum.

The Quantum has a 'Hidden' mono channel, which is the TalkBack channel on input 27. If this didn't exist, I could add another audio device, so it could continue with Stereo Pairs 27-28, 29-30 and so on...This way, it will show up correctly as Stereo Pairs in Logic (or any DAW)

What happens though, is the TalkBack channel inserts a mono channel, that knocks the stereo sequence off by 1, so instead of the additional audio device starting from 27-28, it has to start from 28-29...this cannot be done in a Logic unless I set up 2 mono Audio channels, because the stereo pair sequence is off by one.

If the TalkBack channel could be disabled so the last input channel for the Quantum ends at 26, then this would work.

Ok that is clear.
Send a ticket to support ( with that explanation) and create an FR to add that ability.
