PG-800 MINI Desktop Controller DIY Kit for Roland JX-8P, Super JX, GR-77 and MKS-70

Regular price $265.00 Sale

The PG-800 Mini is a compact controller for the Roland JX-8P, Super JX, GR-77 and MKS-70 synthesizers.   The desktop controller kit is available in 2 configurations: 

Full kit - This includes everything needed to build the Pg-800 Mini Desktop.  Kit contains parts to build cable.  SMD soldering experience required.  ($299)

Partial kit - This includes a PCB, programmed processor, the external enclosure + front panel, 44 Song Huei Tall Trimmer type pots, parts to build cable, mounting hardware, 4 rubber feet.  SMD soldering experience required.  ($265)

 

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.   Page 2 parameters are shown below:

 

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 88 parameters can be controlled with the PG-800 Mini and a Vecoven upgraded JX.  

 

Firmware updates will be made available if and when new features are added to the software.
