The pitch-bend wheel is on the left of the modulation wheel.

Such a device provides a musical keyboard and perhaps other actuators (pitch bend and modulation wheels, for example) but produces no sound on its own.

Electronic keyboards often have two wheels on the left hand side, generally known as a pitch bend and a modulation wheel.

The modulation wheel is usually set to control a tremolo effect by default.

An octave down switch by the modulation wheel is also available independent of memorized settings.

The chorus circuit board is immediately underneath the modulation wheel.

Toggles between enable and disable of both the pitch-bend and modulation wheels.

Pitch bend and modulation wheels are placed above the keyboard aligned to the left.

The front panel features a standard setup of a pitch bend wheel, a modulation wheel and a master volume slider.

There are assignable pitch, modulation wheels, and two patch select buttons.
