The Native Instruments S61 MK2, is a MIDI controller keyboard with 61 keys, designed to intergrate directly with Native Instruments software. Of key importance in the MK2 are the all new colour screens that can display different information from NI based software, Machine or your DAW. There are more buttons with direct access to key features, in a newly designed layout. The MK2 models have included traditional pitch and modulation wheels, replacing the touch-strip style sliders on the original. However, NI have included a horizontal modulation touch-strip below these two encoders.
