The Retroaktiv PG-800 Mini is a compact controller for the Roland JX-8P, Super JX and MKS-70 Synthesizers. This kit comes in two configurations:

  • Kit 1: An Internal Controller Kit for mounting the PG-800 Mini inside of a Super JX or JX-8P Synthesizer
  • Kit 2: A Desktop Controller Kit for building a standalone unit

The kit includes:

  • PG-800 Mini bare PCB
  • PG-800 Mini Graphic Overlay
  • Programmed microprocessor
  • Bill of Materials
  • Drilling Template (Kit 1)
  • Mounting hardware
  • 44 tall trim pots
  • Case Hardware & 5′ DIN cable (Kit 2)


The PG-800 Mini has all of the functions of the original PG-800, plus some new features. New functions include:

“Scratch patch” generator – Tapping a button will generate a basic scratch program, which serves as a useful starting point when creating a new tone.

Random patch generator – Holding a button down will generate a random tone. This is a fun way to discover new sounds from the JX.

Copy & paste – Copy the current state of the knobs on the PG-800 Mini to save your ideas or easily transfer a tone to another program.

The controller is also compatible with Super JX synths which have the Vecoven upgrades. The Mini can now also operate in “Vecoven 4.x mode”, which adds a Page 2 button, giving hands on control over all of the 40 extra tone parameters in Vecoven 4.x firmware, plus UPPER/LOWER BAL, and aftertouch parameters for VCF, VCA, and vibrato. PG-800 Mini controls 92 parameters on a Vecoven upgraded Super JX.

This kit requires SMD soldering.  The smallest part used is  0603 caps and resistors.  Board connects to the JX via 5 wires.  This should be installed by people with electronics experience.  Drilling into your synth is permanent.  Be sure to do a good job and follow the instructions closely.

The installation manual includes a link to a full Mouser cart, so you do not need to spend time searching for the electronic components, it can be done with a couple of clicks. Schematic link is provided to all who purchase kits.
