Vortex Sound Research

Hi! So, finally managed to pick up a mono synth. Was between sub 37 and pro 3 but a used pro 3 came up at a reasonable price so picked it up!

In our living room (sadly no home studio for me) I have a digital piano (Nord Grand) and the pro 3. For now, just using with headphones but need a simple but high quality mixer.

Any recommendations? Hoping to add a poly synth also, maybe drum machine. So, would need 4 stereo inputs. Most of what I see when searching has multiple different types of inputs for microphones etc which I don’t need.

It’s purely for home playing, mostly headphones but will also be hooking up to my studio monitors which are in the same room.

Any suggestions?
