In electronic music, a pitch wheel is a control on a synthesizer to pitch bend (portamento) — to vary the pitch in a continuously variable manner. The first synthesizer with a pitch wheel was the Minimoog, in 1970. Alternatively, pitch bend controllers on synthesizers may have appearance of joystick, knob, or ribbon. In the MIDI specification, the pitch wheel may send 16,384 possible variation values. The General MIDI specification recommends that the total range be ±2 semitones,〔(Pitch Wheel ) (MIDI specification)〕 though this Pitch Wheel Range (or Sensitivity) can be adjusted using General Midi Registered Parameter Number 0, 0. ==See also== *Glissando 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「pitch wheel」の詳細全文を読む スポンサード リンク
