MIDI Adapter Operation Description
The MIDI adapter makes use of the existing Cordovox spring contacts to sense when a
key or button is depressed. A microprocessor together with CMOS SMD integrated
circuits are used for converting the switch data into the MIDI format offering reliability,
small size and lightweight. The possibility of false key or button readings is reduced
using a combination of circuit and software program strategies.
The power input can be either through the special MIDI cable or by a separate power
input socket located beneath the MIDI adapter box in which case a standard MIDI cable
can be used.
