ROLAND JX-3P - A Creative Instrument from the Past to the Present

The Roland JX-3P is a six-voice polyphonic synthesizer, introduced in 1983. It was one of the first synthesizers to combine analog synthesis with digital control, allowing for stable tuning and easy sound programming.

The JX-3P was designed as an accessible instrument for musicians who wanted high-quality sound and also straightforward operation. Thanks to its built-in sequencer and the ability to expand its controls with the PG-200 programmer, it became a popular tool for electronic music, pop, and film production.

Sound Architecture and Flexibility

The JX-3P features two DCOs (digitally controlled oscillators) per voice, giving it stable tuning and rich harmonic possibilities.

Key Components of the Sound Architecture:

•  6-voice polyphony – Allows for complex sound layering.
•  Oscillator Sync, Frequency Modulation, and Cross Modulation – Provide expressive
   sound design capabilities.
•  Multi-mode resonant filter (IR3109) – Offers low-pass and high-pass modes.
•  One LFO per voice – Enables frequency, filter, and amplitude modulation.
•  One ADSR envelope generator – Shapes amplitude and filter.
•  Built-in stereo chorus – Adds depth and spatial character to the sound.

Built-in Sequencer – 128 Steps for Creative Composition

The JX-3P includes a built-in 128-step sequencer, which allows up to six notes per step to be recorded.

Main Features of the Sequencer:

•  Synchronization with external devices – Connect to a drum machine or other synthesizers.
•  Easy-to-use interface – Sequence programming via panel buttons.
•  Polyphonic sequencing – Allows for multiple-note layering within each step.

The built-in sequencer makes the JX-3P an excellent tool for live performance, enabling quick creation of rhythmic and melodic sequences without requiring an external sequencer.

Roland PG-200 – A Programmer for JX-3P, MKS-30, and GR-700

The Roland PG-200 is an external programmer, designed specifically for Roland JX-3P, MKS-30, and GR-700. This hardware controller provides direct access to all parameters of these synthesizers, making sound programming significantly easier compared to using the standard menu controls of the JX-3P.

Thanks to its extensive interface with rotary knobs and slider controls, the PG-200 enables intuitive sound parameter editing, making it ideal for musicians who prefer hands-on control instead of navigating digital menus.

Key Features of Roland PG-200:

•  Complete control over JX-3P, MKS-30, and GR-700 parameters – Allows fast editing of
   oscillators, filters, envelopes, and modulation.
•  Connection via 6-pin DIN socket – Special cable for connecting to compatible synthesizers.
•  Physical control over parameters – Provides instant access to all JX-3P functions.
•  Dedicated controllers for oscillators, filter, envelopes, and LFO – Simplifies sound programming.
•  Manual mode button – Instantly switches the synthesizer to direct editing mode.

Benefits of Using PG-200:

Using the PG-200 significantly speeds up the sound design process, eliminating the need to navigate menu screens on the JX-3P.

Main benefits include:

•  Immediate parameter adjustments – Instantly control filter, envelopes, LFO, and other elements.
•  Greater creative flexibility – Enables real-time experimentation with sounds.
•  Ideal for live performance – Quick access to parameters makes PG-200 perfect for concert use.

Dtronics DT-200 – A Modern Alternative to Roland PG-200

The Dtronics DT-200 is a modern hardware programmer, designed as a replacement for Roland PG-200, originally made for Roland JX-3P, MKS-30, and GR-700. This hardware controller offers full parameter control, making sound programming much easier compared to the menu-driven interface of the JX-3P.

DT-200 is designed to faithfully replicate the functionality of PG-200, but with improved durability and modern technology, ensuring reliable operation and better ergonomics.

Key Features of Dtronics DT-200:

•  Full compatibility with Roland JX-3P, MKS-30, and GR-700 – Works as a dedicated sound
   editor for these synthesizers.
•  Complete control over parameters – Allows fast editing of oscillators, filters, envelopes, and
   modulation.
•  Connection via 6-pin DIN socket – Special cable for connecting to compatible synthesizers.
•  Powered by the synthesizer itself – Does not require an external adapter, making setup simpler.
•  Durable metal construction – Robust design for long-term professional use.
•  LED indicators – Improve visibility of parameter settings.

Why Is DT-200 So Valuable?

Since the JX-3P uses deep sound layering, programming sounds solely via the synthesizer’s panel can be time-consuming. DT-200 significantly accelerates this process, allowing for instant access to complex sounds, which are essential for expressive sound design.

Connectivity and MIDI Features

The JX-3P is equipped with MIDI In/Out 5-pin DIN connectors, enabling integration with external sequencers, DAWs, and other synthesizers.

MIDI Capabilities:

•  Basic MIDI message support – Note On/Off, Pitch Bend, Hold, Modulation, and Program Change.
•  Connection with external MIDI devices – Synchronization with other synthesizers and sequencers.
•  Limited MIDI implementation – Does not support System Exclusive or Continuous
•  Controllers, meaning real-time parameter editing via MIDI is not possible.

The JX-3P was one of the first Roland synthesizers with MIDI, making it a historically significant instrument in the digital revolution of music technology.

Artists Who Used Roland JX-3P

The Roland JX-3P was a favorite instrument among musicians who appreciated its unique sound combined with digital control.

Notable artists who used the JX-3P include:

•  Toro Y Moi – Experimented with JX-3P on his early albums.
•  Venetian Snares – Used JX-3P for complex electronic textures.
•  The Future Sound of London – Featured JX-3P in ambient and experimental music.
•  Mac DeMarco – Incorporated JX-3P into his lo-fi productions.
