"The PG-800 Mini is a compact controller for the Roland JX-8P, Super JX, and MKS-70 synthesizers. This unit comes fully assembled, tested, and ready to be plugged into a JX. Units are available in black gloss and matte black cases.

It has all of the functions of the original PG-800, plus some new features. The PG-800 Mini fits perfectly atop the JX-8P and Super JX synthesizers, measuring just 7.75" x 4.25" x 1.25". 5' DIN cable is included with all orders. All units are equipped with non-slip feet to keep the unit firmly seated on any surface. The PG-800 mini will work with all JX8P, Super JX and MKS-70 synthesizers. 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.

The PG-800 Mini features some useful functions that the original PG-800 did not have. 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.

Page 2 - Booting up in "Vecoven 4.x" mode will turn the WRITE button into a Page 2 function. All 40 extra tone parameters can be controlled using this function. Parameters include all PWM, LFO2, ENV1-4, LFO sync, upper/lower balance, aftertouch vibrato amount, aftertouch VCF amount, and aftertouch volume amount. A total of 92 parameters can be controlled with the PG-800 Mini and a Vecoven upgraded JX.

These have been discontinued at Retroaktiv. Probably hard to find. And a lot cheaper than a vintage PG-800!"
