organ sounds; it must be connected to a MIDI controller keyboard to be used. The tabletop units vary in sophistication. The least sophisticated units provide a selection of commonly-used tonewheel sounds. More sophisticated units may have drawbars and a number of knobs and buttons for controlling the sound. The third format is as a virtual instrument, which requires a computer and monitor. The virtual instrument may depict the same types of controls that a real tonewheel organ would have on the monitor. The musician then uses a computer mouse or other input to change the settings.
