Earlier this week we brought you news of Syntedon's Web MIDI Editors for the NORD 2X and Roland TR-8, now another company, Breadandbuttersounds, has released a free online Roland Boutique JP-08 Editor/Patch librarian. This is the information from their web page...


  • 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] + [9] and then [2] - 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 info@breadandbuttersounds.com for bug reports and suggestions


Breadandbuttersounds say that they are not responsible for lost presets, other effects or damage on your JP-08 or other equipment by using the editor.

Pricing and Availability:
Free. You can run the editor here.
