Bi directional communication with your Roland Boutique JP-08 using Sysex (Important! please see below for setting it up)
Precision editing of all parameters. Use the sliders of your JP-08, the sliders on the web page or enter the exact value for a parameter manually (you will notice that the sliders on the JP08 in itself are quite inexact so an editor like this is necessary for serious patch making)
When you change patch or press Manual on your JP-08 the patch is automatically uploaded to the editor
See parameters and learn from your favorite factory presets
Easy access of important features like the Delay, Portamento and Bend Range
You can save your patches if you log in using a Google Account
A public patch browser utility is planned once we have gathered a number of patches that users are willing to share
Instructions/how to make it work:
Web MIDI is not widely supported yet. The editor will probably only work in Chrome and on a computer (no mobile units).
You must allow sysex access for the web page
The editor will NOT work with the USB connection to the JP-08. (Because no sysex is transmitted over USB with the current JP08-firmware) You must use a separate MIDI interface (5 pole DIN) for both input and output.
You must set up your JP-08 in chain mode if you want it to transmit patches and slider movements. ([Manual] +  and then  - please see the JP-08 manual)
Consider the current version of the editor as a beta version (only tested on Chrome in Windows 8.1 and Mac OS X 10.9.5 so far). Please e-mail email@example.com for bug reports and suggestions
