Device Overview

Name/Version: Roland Super JD-990 Patch Editor 1.03
Author: adamneddo  
Description: This is a synth patch editor for the Roland Super JD990 synthesizer.

It includes controls for editing every parameter of a single synth patch. It does not support editing rhythm sets or performances. It is a MIDI “effect” designed to be used in conjunction with Live's "External Instrument" device.

This editor offers native support for the SR-JV80-04 "Vintage Synth" expansion board.


Save patches you create on the JD-990 hardware itself. Parameters in the editor will not be saved with your Live set.


To get started, bring the Max for Live device and the hardware in sync using the buttons in the lower left hand corner of the device.

"Get Patch" will pull all the parameter values of the patch currently selected on the JD-990 hardware into the Max for Live device. Set the track Monitor to “In” before executing this function. The button will light up while it’s receiving data and go dim after it’s finished working. You can set the track monitor to “Auto” again once this process is complete.

The "Initialize" button initializes all the values of the Max for Live device and the Super JD. The track Monitor can stay on “Auto” while initialization is in progress. The button will light up while it’s working and go dim again after it’s finished.


This patch editor supports the 990's unique "Tone Select" feature for easily editing multiple Tones at once, but does so in a slightly different way from the hardware.

The Tone you select using the tabs at the left of the device will always be edited when you make a change to one of its parameters. To edit additional Tones at the same time, click the pencil icon on the tab of one of the inactive Tones. Parameter changes you make will be sent to all active Tones.


This is the first Max patch I've shared for public consumption so it's probably not perfectly optimized. I've made an effort to make it as clean and readable as possible, but I'm still learning so cut me some slack. Feedback from more seasoned developers is welcome and appreciated!
