Q182RP20, Ribbon Controller 20"
The RP20 is a position and pressure-sensitive ribbon controller capable of replacing or augmenting a traditional keyboard in an analog synthesizer system. The RP20 can be held like a guitar, played from the desktop, or mounted to our modular keyboard controllers above or below the keys. The RP20's sensor is 20"" long and produces a voltage for the position of your finger and a voltage for the pressure you're applying. These voltages are produced using analog circuitry and change smoothly and naturally as you play. Both position and pressure signals have adjustable ranges using our Q182 dual controller interface module. When the position sensor is set to the 2 volt range, the ribbon can be played like a keyboard, complete with a template showing white and black keys. The 4/12th volt range is useful for pitch bending of +/-2 semitones, and the 5 volt range can be used for wide filter or pitch sweeps. A gate signal can be produced from either sensor and used to control other
