This is the first GINO-MIDI Interface, it’s called the Small-MIDI 4.
The configuration that the Small-MIDI 4 Interface can handle consists of:
- two 5 octave keyboards and a large pedal and a register panel of up to 64 registers, or
- three 5 octave keys and a large pedal, or
- four 5 octave keys
It can handle a total of 4 x 64 switches. The PCB is 80 x 52 mm.
The heart (brain) of the interface is a Atmel microcontroller. This circuit can be powered by a very simple adaptor that delivers between 8 and 12 volts. This circuit consumes approximately 15 mA.
A 20-pin ribbon cable, called the GINO-Bus goes to the decoder-PCB’s or the Decoder_Matrix-PCB’s which are connected on the keyboards, pedal or registry panel. With the GINO-Bus you can build your modular MIDI organ. This small interface is the heart of your MIDI organ.
