The keyboard is wired to a 2HP connection module via a 3.5mm stereo cable. The connection module is mounted at a suitable position in the upper or lower row of the A-100PBK. The connection module has a midi output available (3.5 mm stereo midi standard) which outputs the midi data of the keyboard (midi channel 1, lowest note number 36, note on/off and aftertouch).
A polyphonic (A-190-5) or monophonic CV/Gate interface (e.g. A-190-3, A-190-4) can be connected to the midi output of the connection module. By means of two jumpers one can choose between the two midi standards for 3.5 mm midi connectors. A 3.5mm-to-DIN5 adapter cable is included with the A-100PBK.
