Almost all of Hypno’s parameters are mapped to MIDI CCs, so you could use the NK2 to get more hands on control of the module. The most common use would be giving the “Page” parameters their own dedicated controls, so you don’t have to do button combinations on Hypno.
The MIDI Implementation for Hypno is listed on our Manual Page, use this with the Korg software to program your NK2 to control whichever parameters you desires.
Note that you will need a USB OTG dongle (microUSB adapter) to connect the NK2 to Hypno. There’s a list of compatible hardware here
