FM synthesis has traditionally ignored knobs and hands-on controls for a good solid menu system that handles the many many parameters. This often makes it an unloved form of synthesis – great sounds but a pain to program. The Yamaha Reface DX manages to capture both the FM sound that we love and the menu driven programming that we don’t. Dtronics have an answer. It’s called the DT-RDX and it makes the Reface DX as knobby as any other synth.



It’s a hardware controller designed for the Yamaha Reface DX. You sit the Reface in front and the DT-RDX looms over the top. With its 41 knobs and 9 switches, it’s pulled out 50 parameters to give you direct access to.

The controls are split into two halves. On the left side are common controls that affect the sound/patch/program as a whole. On the right are the operator controls. The Reface DX uses 4 operators and you can either apply the controls to one operator at a time or select as many as you want to control at once. For operator control you have parameters like envelope rate and level, tuning, curve, pitch envelope, frequency mode, pitch and amplitude LFO and feedback. In the common section there’s control over pitch and amplitude envelopes, LFO modulation and algorithm select.

The DT-RDX is a fabulously elaborate way of opening up the programming of the Yamaha Reface DX. It will cost you about the same as what you spent on the Reface but if you want to get under the skin of FM then this is going to make your life so much easier.
