uMix 4x2 with Dual Effects Sends

#uMix 4x2 with Dual Effects Sends

This is remix of the uMix modules @stschoen recently uploaded. I thought I would add a couple of effect sends. Up to four mono inputs are mixed with two stereo effect inputs into a stereo output.

The mixer bus for send A includes send B so you could send one effect into the other.

Effects sends are sending a stereo signal, so there is no need to make two copies of effects modules within Audulus.

Very nice, that one is going on the right click menu. A little explanation of the “extra” knob and the fact the busses are stereo would be helpful. Took me a bit to figure out how it worked.

I will definitely add notation, it’s just that the template wasn’t auto-filled and it was too late at night. :zzz:

No problem. I expect you’re worn out from doing the 1-Toast. What a massive job to document that one :cowboy_hat_face:

This is great but totally impractical for iOS – too much CPU. Any chance you can gut it? A version without pan, switch to mono sends? I am not sure how much processing each of these features takes up. Maybe a better move for this would be just an effects send module that can be inserted ahead of any mixer inputs. I don’t know how this sort of stuff works so I am just throwing out some ideas.

Reducing it to mono shouldn’t be too much hassle.

This module uses 0.03% on my computer - what I’m thinking is happening is you’re sending a high poly signal into it to test? Is that so?

At a quick glance I think you are right. I loaded it up with something else and it only used 5%. I am not sure what I was running. I think I tried to use it twice and it maxed things out. So I figured that if you have enough going on to me mixing 4 tracks with A and B sends, you can’t really used a mixer that is heavy on the processor. I will definitely have a closer look.

Remember also that 5% is also a proportion of the total usage of Audulus. So it’s not 5% of your CPU, but 5% of the total % that Audulus is using.
