Hello,

I am currently utilizing a No Slew NxM Mixer for mixing audio in my application. I would like a "Router" gui control that utilizes the same instructions and organizes the volume data into sequential memory locations like the No Slew NxM Mixer. I utilized the sequential memory to bulk write many controls at the same time. The checkbox\text input method for the router is much easier to work with.

I am using the following mixers in my program:

6x 32*16

12x 16*8

Audio Signal Processors

Hello Natan,

Have a look at my answer to this recent post. I explain how to use the Audio router cell instead of the NxM mixer cell. I think this will be more useful for you.

That is exactly what I want to do but the router uses many more resources than the NxM block...

Hello Natan,

But the interface to an external controller is much more efficient. If you are making changes frequently of many controls then I would think it is a good tradeoff. This is why we give you several different cells, you have choices.
