MPG-70 for Super JX & MKS-70  Pre-order

MPG-70 for Super JX & MKS-70 Pre-order

Regular price $850.00 Sale

We are taking pre-orders for the MPG-70 7U rackmountable controller for the Roland Super JX and MKS-70 synthesizers.  This controller was specifically designed for units that have Vecoven 4.12 firmware and PWM boards installed.  The MPG-70 gives access to all of the extra voice features added by the expanded Vecoven mods. 

Update 10-10-18: Shipping will be delayed by a few weeks due to a delay in manufacturing.   We're working as hard as possible to get these tested and shipped quickly.  Thanks for your patience.


Pre-order period will end when units begin shipping.  Due to newly implemented tariffs, the retail price of the unit will be increased.  Pre-order price of $850 will be offered until the date of shipment, at which point the price of the assembled units and kits will be increased to reflect the new cost of production.  

The module is available in 2 configurations.  A fully assembled unit can be purchased for $850 + shipping. This includes one 3' 6 pin DIN cable.  8' DIN cables can be added to your order for and extra $10.

A full DIY kit (all parts included) is available for $650. 

The module features 96 controls and several buttons, a front faceplate, and a rear sheet metal enclosure.  The enclosure allows the unit to be angled forward and set on a tabletop like a mixing board, as well as be rackmounted.  The controller uses the 6 pin DIN cable to receive power from the JX.  


96 controls parameter controls, including all Vecoven 4.x PWM parameters

Full MIDI implementation.  Sends MIDI data via sysex, MIDI CC, or PG-800 protocol.   Midi input merges incoming data to be sent to the JX, so no need to merge the MPG and your MIDI controller to play the JX while editing.

Can be used with stock JX8P, Super JX, and MKS-70 while simultaneously controlling a Vecoven modded JX.  (Control and many JX synths as you wish)

UPPER/LOWER/BOTH/AUX feature allows editing of upper and lower tones simultaneously or separately, and a separate "aux" channel allows for more JX synths to be added and adited separately.

Patch menu gives user direct and quick access to deep patch parameters including assign mode, glide, key mode, patch detune, chromatic detune, tone select, and more.  

Full featured random tone generator allow tones to be generated randomly, or by selecting a random category such as pad, poly, bells, bass, etc.  Each section of the synth can be masked (not changed) when a random tone is generated.  The amount of randomness can be selected by the user.

ASSIGN A/ASSIGN B/ASSIGN PEDAL - Three assignable controllers allow up to 5 parameters to be controlled simultaneously with one knob/pedal.  User can set the parameter, the max and mix, and whether to invert each layer, allowing for one to do something like turn the filter cutoff up while turning the resonance down and increasing the LFO rate with one control. CTRL A default function on boot-up is a crossfade between mixer channel 1 and 2.  (The assignable controls can be set to anything the user wants)

Intuitive menu browsing and data entry makes creating a patch quick and intuitive.

Scratch tone generator allows user to select one of several basic starting places for creating new tones.  Manual is also available to transmit the current position of all sliders.

Sliders can be set to output MIDI CC messages that can be easily recorded and played back with any DAW.  

WRITE button has a dialog that checks before the synth is sent the command to save the current tone location.
