Click here to see videos of the Appendage in action! The Appendage is not a simple ribbon controller. The Appendage is a ribbon controller specifically designed to control multiple functions of an analog synthesizer from a single control surface. The Appendage produces a number of voltages: Initial Note Voltage, Slide Voltage, Bend Voltage, and TFS voltage (which is proportional to the distance between two points of contact). These voltages are available individually in normal and inverted form, and a mix section is provided so that a blend of these control signals can be generated. In addition to the control voltages it produces, the Appendage also produces gate and trigger signals, with three different triggering modes. The Appendage provides modulation inputs and calibrated mix inputs and sample inputs. The Appendage utilizes a very high stability, extremely low droop sample and hold system. Its unique signal acquisition circuitry allows control with very slight pressure, thus the moniker "touch ribbon". The Appendage accepts external gate signals for synchronization with external devices and can also be used as a very high quality sample and hold/track and hold system. The Appendage can be used as a pitch controller and as a modulation controller simultaneously through manipulation of the ribbon surface and various control settings of the Appendage.
