With an expanded front panel proffering one-knob-per-function control as a workflow-raising result of this high-class synthesizer’s palpable physical makeover, also allowing for six freely-programmable Macro buttons with which users can define functions from a wide range of features for additional performance control. Tremendous tonal changes flow freely when playing the Iridium Keyboard live since polyphonic aftertouch is transmitted individually for each note played. Performers can conceivably play and hold down any number of keys simultaneously, subsequently moving each finger individually. In other words, individual keys are affected by the pressure applied by each finger, thereby creating, for instance, individual data streams for modulation purposes, whereas with monophonic (Channel) aftertouch all notes played will respond in the same way.
