GrooveBox Editor for Roland MC-505, MC-307, JX-305 and D2

GrooveBox Editor Beta– Standalone and VST Editor for Roland MC-505, Roland MC-307, Roland JX-305 and Roland D2 series synthesizers

Multitimbral Midi Editor for Roland MC-505, MC-307, JX-305 and D2 Groove synthesizers. Complete control of all your synthesizer (8 Patch parts, Rhythm part, Effects, Part Common and System settings) from a single instance.

Beta release, any feedback will be welcome.



Load and save patches and rhythms from the synth's banks and from files in .syx format, and create new soundbanks with drag&drop of patches between banks.

Data Storage

Save the synth status (all Patch, Part Settings, Part Common and System Settings) in a single .syx file. Backup Pattern and Patch data performing a Bulk Dump.

DAW Automation

Every parameter of the sound engine of every part is ready to be automated using the hosted version.

Total Recall

GrooveBox Editor lets you edit all the Patch, Rhythm, Part Common, Part and System parameters (up to 8848 parameters!) and save the latest edit status within the application. This means that you can easily recall the latest status of the previous edit simply by opening GrooveBox Editor.

Parameter Locking

Lock any section of the synthesizer sound engine. For instance, lock Tone 1 Wave section and Amplitude Envelope. When loading or receiving a new patch, the locked sections will not change. Do you like the effect settings of a Part, or the filter section? Lock them and test any patch with those settings.

Patch Randomizer

GrooveBox Editor provides a Patch Randomizer with several functions to control the process. It can be used together with Parameter Locking section to select which groups of parameters will be randomized.

…and many more features like the Joystick Modulator (choose up to four parameters from any part and modulate them in a vectorial style), copy & paste Tones and Patches, multi-tone editing, scalable GUI, 11 skins to choose…


The zip file contains both stand-alone and VST plugin version for 32 and 64 bit Windows systems, as well as a short manual.

Fixes v.02 (16/12/2017):

  • Parameter EFX Delay Send Level was missing.
  • Parameter EFX Reverb Send Level was missing.
  • Parameter FMX Color didn’t send it’s value.
  • Parameter FMX Depth didn’t send it’s value.
  • Parameter Tone 3 Pitch Envelope Depth didn’t send it’s value.
  • Skin Saturn fixed (was missing a color, resulting in broken GUI or crashes when this skin was selected at startup).
  • Modulation destinations are now correctly displaying their names.
  • Sending Part Info Data (pressing Send Data button) as a whole was causing problems (initializing patches), so now this data is sent in a different way.
  • Added missing CC tab to Drum part.

  1. Hi, was looking for a way to back up my 307, after i had a memory corruption and lost 10 years of patterns and patches … ggrrrr.

    Found this and it looks amazing – what a public service by Dasfaker!

    I can get it set up and ‘online’, all seems to be connected, but I tried to backup with a bulk dump by pressing “get” under “bulk dump”, it said “waiting”, and i set the 307 to transmit bulk dump (pattern & patch). somehow it didn’t work, and i wanted to try again but the buttons which said “get” now says “done”, and no matter what I do I cannot get it back to saying “get”!.

    I’ve tried closing and reopening the application, i’ve tried unplugging midi channels, turning the 307 off and back on etc.

    Any thoughts appreciated! 🙂

    Thanks again.

  2. …just to add to the above, as I understand that there is no other way to get sequence data (patterns) out of the 307 and into the computer beyond the bulk dump approach? thx

  3. Hi danhaglund

    When you press “get” the button label change to “waiting”. Then you must perform the dump operation on the 307. When it’s done (there is no progress bar to indicate the dump status so you must look at your 307), you must press again the button labeled “waiting” to save the file to disk.

    I can’t reproduce your issue here. Sometimes the button “waiting” is pressed when I open the editor, but pressing again and reopening the editor fix the button.
    Try deleting folder GrooveBoxEd located in C:\Users\User\AppData\Roaming and reopening the editor.

  4. Hi! I’m having some trouble getting the stand-alone program (.exe) program to recognize my MC505 as a MIDI device. Looking at my device manager, I think it might be an issue with having the right driver – showing up as a “USB Composite Device”.

    I took a look at Roland’s MC505 USB< ->MIDI drivers but there seems to be minimal support. Looks like they only have drivers for OS X Yosemite. I also contacted Roland tech support and they don’t seem have any windows drivers.(

    Does anyone have any experience with MC505 drivers for Windows 8/10? Do y’all just plug your MC505 into your computer via USB and it works or what!?

  5. Hi dgarges

    The Roland MC505 doesn’t need a midi driver. What probably need a driver is your MIDI interface, where you connect the MC.
    What MIDI interface are you using?

  6. Thank you so much for this amazing editor. I have used every Groovebox editor and this is the best one by far.

    I am having an issue with the scale tune section. The scale presets and the individual cent tune boxes do not have any effect on the MC-505’s tuning. It does work with a different editor (“MC-505 editor”) . I also noticed that when I change the tuning manually inside your Groovebox editor and then save a patch, the cells for the cent tune default back to zero.

    For now I am running both editors simultaneously and using the other for scale editing, but would love it if I could do everything in your editor since it allows manual cent tuning.

    Thanks again for your great work and thanks for your time.

  7. Hi Apheleon.
    Thanks for your words and for your report.

    I can’t reproduce your issue here. Be aware that the scale tune boxes and presets works per Part, that means that any change you make is applied only to the current part selected, not all parts. If you want to assign the same values on all parts, click the menu button and select “assign current to all parts”.
    Also, don’t forget to activate Scale Tune button (click System button in the upper side of the editor to show System menu)

    About the second issue, I doesn’t happen here. It could be that you loaded the patch on a part that has no scale tune? Scale tune data is not part of the Patch data, it belongs to System data, so when you save or load a patch it does not contain any scale tune data.

  8. Hi Dasfaker,

    I’m using Bitwig 2.2.2 and it is trowing this error:
    “com.bitwig.flt.library.metadata.reader.exception.CouldNotReadMetadataException: could not read metadata: Could not read VST plug-in metadata
    64 bit plugin host reported errors: Pluginhost returned non zero exit code -1

    32 bit plugin host reported errors: Pluginhost returned non zero exit code -1”

    Previously in Bitwig 1.3 I was using the older version of the editor with no problem (it is not working in 2.2.2).

    Same goes for Studio One. Reaper is howerver reading it no problem as well as Cubase 5.
