With the growing interest in Virtual Pipe Organ projects and prospect of converting manuals, a pedal board and stop keys to a matrix wiring configuration, a circuit and card was developed that allows use the existing organ console wiring. The MIPC-1A features 64 inputs that requires no diodes or switch buss rewiring, simply connect a wire from each key or stop contact to the corresponding input on the MIPC-1A. 

The MIPC-1A has been designed to make the installation as effortless and easy to understand with two types of wiring options.  To further simplify the installation, there are no programming codes write or install.  Simple DIP Switch selection for Keyboard/Stop mode, Midi Channel and Four Analog (Swell Shoe) functions.

The MIPC-1A Input to Midi Controller is the best and easiest to install device for that VPO project.
