MPG-8 is an affordable, compact controller for Roland JX-8P, MKS-70, and Super JX synthesizers.    The MPG-8 does everything the original PG-800 did, and more.  The case is constructed using heavy-duty powder coated metal, and it sits atop any desktop surface or the synth itself using 4 non-slip rubber feet.  The 6 pin DIN port is recessed to reduce the length of protruding 6P cable when unit is plugged in.  Supports all stock, Vecoven 3.x and Vecoven 4.x units.

MPG-8 uses the included 6-pin DIN cable included with the unit to communicate to the JX, and to receive power from the synth.  

MPG-8 has all of the features of the original PG-800, plus more.  MPG-8 can be configured to boot in "Vecoven mode" which will allow users to control the extra parameters added by the Vecoven 4.x/PWM modification.  Features include:

Manual mode - transmits current position of all knobs to the synth

Scratch Patch Generator - sets up a generic starter tone.  Has 3 scratch tone types: basic dual DCO, oscillator sync, and dual pulse width modulation.

Vecoven/Page 2 mode - allows users to access all Vecoven parameters

Randomizer - Creates musically useful "randomized" tones at the press of a button. 

Power up with both buttons held to toggle between booting in stock or Vecoven mode.  This only needs to be done once, then the MPG-8 remembers it.












 June 2020 - Prices have been raised on these because we have been forced to pay a 25% tariff on our pots, sliders, slider caps and knobs.  These are only available from one place in the world, and if we buy from there, an excessive 25% tariff is assessed.  We are forced to pass this cost on to our customers.  China doesn't pay for these tariffs, Retroaktiv does.  Tariffs are bad for US based businesses and force us to hire less, pay more to make our goods, and charge more to the consumer.
