Description
This keyboard scanner is ideal for keyboards with one long busbar. With this application you do not have to divide the busbar into 8 pieces as with the Decoder with Matrix.
A keyboard scanner can be used for a keyboard, pedal or stops and can read a total of 64 switches.
The main board’s microcontroller (Small-MIDI or Big-MIDI) sends a signal to every keyboard scanner or decoder circuit in the entire GINO-MIDI system, every time, saying, “Now it’s your turn to cycle through the keystrokes”.
This PCB contains a decoder circuit and 8 Octal Line Drivers that are controlled by the decoder circuit. The decoder circuit forms the link between the MIDI main board (that can be the main board of the Small-Midi or the main board of the Big-MIDI) and these Octal Line Drivers.
This PCB can be directly connected to the GINO-BUS. The key contacts (or the stop switches) are connected directly to the keyboard scanner by means of a 16-pole flat cable. This flat cable is connected to the PCB by means of the well-known IDC connectors.
The dimensions of this PCB are: x cm by y cm. The PCB is quite narrow so easy to place somewhere behind a keyboard. This PCB can also be used for a 32 tone p edal and for connecting stop switches. The maximum number of switches to be connected is 64.The prices of the 16-pole flat cable can be found on the order page. For a 5 octave keyboard you need approximately 1.5 meters of 16 pole flat cable.
