1 Setup
Intended use
The DT-RDX is intended to create new sounds for your synthesizer.
The second edition DT-RDX has a new hardware controlled MIDI merger.
This makes it possible to play your connected Synth over MIDI when the
DT-RDX is attached in a reliable way.
What is included
Please ensure that your DT-RTX includes the following:
• DT-RTX v2 Programmer (in the main box)
• Mini Din Male-Male MIDI Cable (in the second box)
• Dual Male to Female Y Power Cable (in the second box)
Installation
Installation of the programmer onto the REFACE is simple and requires no
tools.
Carefully align the 4 little pins of the DT-RTX with the holes under the
reface body and slot them together with gentle pressure.
Be advised: the programmer and controller are loosely connected and
can easily come apart.

Connection
Connect one end of the small MIDI cable to the REFACE port of the DTRTX. Connect the other end to the MIDI port of the REFACE.
Connect the midi-splitter cable that came with your reface to the MIDI port
of the DT-RDX
Now connect one male end of the Y POWER CABLE to the
REFACE power port and the other end to the DT-RDX power port.
