Mixars Primo (https://mixars.com/product/primo/) is a wonderful piece of hardware! I'm not the only one say that. find below some reviews:
"Mixars has built itself on making hardware that over-delivers on features without costing an arm and a leg... It is hard to find a controller of the Primo’s size and price that can match the features it has. For a DJ like myself who likes to beatmix manually the larger jogwheels and long throw pitch faders makes me reach for the Primo instead of other mid-range controllers" (from Digital DJ Tips, https://www.digitaldjtips.com/reviews/mixars-primo-serato-dj-controller/)
"The Mixars Primo is a 2 channel Serato DJ Pro mixer with 2 hardware channels, filter FX on the mixer, booth output and an excellent build quality...The Mixars Primo took a long while to arrive after its initial introduction, but it was worth the wait!" (from DJTechZone, https://djtechzone.com/mixars-primo-serato-dj-pro-controller-review-and-video/)
It sounds to me a rock-solid product like those released (years ago...) by Vestax or Rane! Currently, Virtual DJ and Serato DJ Pro fully support this controller.
Is in the plan of the developer team to give the official Traktor support to Mixars Primo?
