Review: really cool keyboard - i like that it plays like a laptop keyboard. also you can enable semitone transposition in the xkey plus app.
Review: Make sure you get the USB-C and not micro-USB version - MAKE sure that you get the USB-C version - the older Micro-USB version that was still shipped earlier this year suffered from the usb 'impacting' unless you lined up the connector exactly, rendering it useless. Otherwise great keyboard!
