drift box RM - Analogue Synthesizer

The REON drift box range is a collection of beautifully crafted boutique table-top synthesizers. The designs originate back to the prototype created by founder Shin Arawaka, for his own performances on the underground synth scene in Osaka. Hand-assembled in Japan, REON drift boxes are made using traditional through-hole components, the same technology found in many of the much-revered vintage synths of past decades.

Despite its familiar layout, the drift box RM is like nothing else on the market and is capable of producing a huge palette of sounds comparable to larger modular systems. Ranging from simple leads and basses to powerful cross-modulation, FM and complex sounds, the drift box RM will surprise even the most seasoned creatives. With an abundance of connections and MIDI support, the drift box RM provides an unrivaled stepping stone between modular and conventional subtractive synthesizers




Oscillator and FM sync is provided with variable modulation depth controls per VCO, the versatile EG has switchable AD/ASR and INV/NOR modes, to sculpt filter, pitch, and amp envelope.

Connectivity and Interfacing

Equipped with numerous input and output terminals, the drift box R can be triggered via MIDI or CV GATE. A CV link switch allows each VCO to be either triggered from a single, or two independent CV sources. CV inputs included for external control of the VCA and filter, all with a working range of 0 -10 VDC.

Made in Japan

REON drift boxes are handcrafted in Osaka Japan using traditional thru-hole components, resulting in products that deliver a truly authentic analogue experience. Presented in a semi-modular format, drift boxes bridge both conventional and modular worlds, delivering a product that can be used independently or integrated into almost any synth setup.
