First I want to make it clear that my review is based on information I could find online form the manufacture. I look forward to others comments regarding my observations.
I own this controller and use it to augment the functionality I already have from a basic bare bones controller. I really like the 8 touch pads and the powerful amount of things I can do with it across 4 decks like hot cues, hot loops, slicer, samples etc. $150 US
Downside is even though I can write or modify existing midi files, it is not native to Djay pro and much of the functionality is not that accessible due to MIDI limitations in being able to know current state.
Reloop Beat Pad 2
I like the dual integrated 8 touch pads. This controller comes with XLR outputs and unbalanced outputs. It also comes with RCA inputs with 2 impedance settings to line-in a turntable or other device. Retails for $599 US
Downside no XLR mic input, It only natively supports 2 Simultaneous Decks. I saw complaints about loop size presets not to most peoples likening.
Reloop Mixon 4
I am very impressed! Supports 4 decks at once, I like the pads close to the front as opposed to the jog wheel. Lots of on controller whistles and bells.
Downside Price $799 US, No RCA inputs, No XLR MIC input. Because of these things really still need my mixer to feed audio system instead of native from controller.
Not sure if this goes under question, idea, praise or problem. Has all of these things.
