I'm stumped lol... I'm looking to run my keyboard mix and get everything I would normally get in my stage wedge, as in ears. I'm looking to have separate stereo control on one channel of all my keys along with a separate control, on one channel, of all the other instruments on stage. Therefore, 2 channels with separate volume control of each, in stereo (or mono when the only option) and be able to adjust my general keyboard level without affecting the mains that are sent to the house p/a. I usually have 2 to 3 sources of keys and will need to have that come back to my ears as one general mix but also want that separate control of the band mix. Is there anything out there for that?
