Nord Piano 4 remained outwardly as red as its predecessor, but it was significantly redesigned inside. Twice as many voices of polyphony, twice as much memory for samples and sound programs, as well as the long-awaited feature of Split Point Crossfades. The virtual hammer keyboard with a triple sensor, which appeared in 2016 on the Piano 3, removes a bit of weight without much loss of responsiveness. Samples of synthesizer's sounds and the ability to apply filters in real time masterfully relocate Piano 4 to the "stage synthesizer" segment, historically started as stage piano.
