I am admittedly new to QC and the sounds and interface are awesome. However, I feel that several “structural” issues in the way of I/O flexibility would make it even better, particularly for the gigging player, where you run into all kinds of uncontrollable situations and manner of connecting to existing local systems. Forum member “GabsBiz” created a post in December of 2024 ([Global Sum to Mono options - Quad Cortex / Feature Requests - Neural DSP](https://unity.neuraldsp.com/t/global-sum-to-mono-options/16524)) that nicely lays out a very useful upgrade to the GLOBAL outputs 1/2 and 3/4 with stereo/mono switching for those outputs in the global settings screen. He even included a matrix of how a mixture of mono and stereo output signals could be supplied to FOH and stage monitoring, or other destinations, that could really improve the performance of the QC in such environments. On the other side of the I/O system, the global input settings for inputs 1/2 are useful but could be made even better if these global settings could be setup as a default and then changeable and storable per preset. This would allow settings for different guitars/instruments/mics per preset. Not being a digital programmer, I can only imagine that “structural” changes like these may be more difficult to implement than a new capture or reverb but I believe they would make the QC infinitely more flexible and thus desirable for most musicians. Thank you P.S. How do I cast a vote for a feature request such as the one from “GabsBiz”? ---

Hello and welcome, We have a separate sum-to-mono request which has a lot more votes: > [@Automatically sum to mono](https://unity.neuraldsp.com/t/automatically-sum-to-mono/4815): > > Thank-you for adding the Multi-out feature in firmware 1.0.3. The only problem is that since I use a mono power amp for on-stage monitoring, this feature is really not usable in my setup without a stereo sum box. Ideally this setup should work with minimal extra equipment and cabling. It would be great if there were at least one multi-out mono option, so I’ll propose the following additional output options: Multi-out 1/2, 3, 4 (I.e. 1/2 stereo, 3 & 4 summed to mono). Multi-out Mono (… And here’s another request for input settings per preset (high vote count): > [@Allow input levels and input impedance to be saved per patch](https://unity.neuraldsp.com/t/allow-input-levels-and-input-impedance-to-be-saved-per-patch/5353): > > Currently the input levels and input impedance parameters are global. This makes it difficult to use the same input with different guitars in different patches without having to adjust the input level. It also makes it difficult to set the input impedance in a scene based on impedance sensitive blocks such as fuzz devices. I often use two guitars on gigs, one with single coil pickups and another with humbuckers. I would like to be able to use them into Input 1 and adjust the input level for eac… To vote, click on the up arrow at the top of the thread. ---

If you want a mono output, just use the left output for your stereo preset. This is how basically all pro audio gear has been for decades. Only effect where it would be tricky is ping pong delay. Otherwise I don’t understand why anyone wants the sum to mono option. So, 1 if you’re using 1/2 and 3 if you’re using 3/4. ---
