From an interview with Boom Gaspar and Josh Evans on Keyboard Mag. "Boom grabs piano and Wurlitzer sounds from a Nord Stage, which he also uses as MIDI controller assigned to channel 16. 'There is also a Novation Impulse 61 controller assigned to MIDI channel 1, and an off-stage M-Audio 25 key controller assigned to channel 5,' says Evans. 'All the MIDI signals are mixed together through a MIDI Solutions QuadraMerge and are then fed into a Muse Receptor 2.'"more
If you use two or more(up to 4)midi controllers on your pedalboard as i do, this merger is the perfect solution!I plug into it my main fx switcher and midi controller which i use on song mode(all songs in my list are saved there)but if i start some jam or just decide to do something new during the show i have a second midi controller(Disaster area DMC3XL gen2)which i use to scroll through my presets on my Mobius or Timeline delay.The merger split bouth midi comands very well and send it to my fxs without problems.
This this is very easy to use and useful. So long as any midi device connected to one of it's MIDI inputs follows standard MIDI protocol by providing 5v, it is MIDI-powered!
