Novation X-Station 25 : Dj Christopher-K's user review
A tip for making this product SAVINGS:
I do not know if we can still buy the Novation Remote 25 Audio that silent around 650 Euros but that price, you can get a free update to turn the Remote 25 Audio X-Station 25.
Other than that, I have the Remote 25 Audio upgrade in X-Station and is an excellent product.
UTILIZATION
Very easy configuration, a USB port, install drivers, reboot and voila.
OVERALL OPINION
Sounds basic but high quality resources. But hey, it's a synth so everything is done.
Personally, I use it more for the MIDI controller for the synth.
