So my question is this: Would it make sense to route the output of the computer to my Yamaha speakers so both my piano and computer are using the same monitors? If so, what is a good way to do this and improve the sound quality and usability of my setup?
Hi KLB. I looked up those studio monitors. They look nice and are powered. I would definitely get some sort of USB interface to plug your keyboard and laptop to and run the output of that to your speakers.
The PreSonus Audiobox looks like a better solution in your case than the Alesis. I guess it depends if you want to mix on a device or on a screen. Most of the popular interfaces just use on screen mixers now so you don't have to play with a big hunk of hardware.
These are fairly popular around here too and I use one as well.
Focusrite Scarlett InterfacesDepending on how much gear you want to leave connected will help you decide how many channels you want. I have the big 18i20 so I can leave my keyboards, guitars, etc. always connected. If you are OK with few channels and just swapping cables, go with a small interface.
