Here is some information about some useful MIDI Sysex codes for the Roland Verselab MV-1. It's an ongoing work and I'll add more codes when I decode them. The MV-1 stands out with its distinctive feature of being tweakable via SYSEX codes, setting it apart from the MC-101 and 707 models.

You'll find this information useful if you're using your Verselab for Live performances, as Sysex MIDI will allow you to control more things on the MV-1. Combined with this Raspberry PI Midi hat I can convert Midi CC messages to MV-1 SYSEX messages.

While the MC-101 and 707 offer impressive functionality, they lack this advanced capability, making the MV-1 a preferred choice for those seeking deeper customization options and precise control over their soundscapes. With the ability to manipulate parameters via SYSEX codes, users can delve into intricate adjustments, unlocking a world of creative possibilities and allowing for seamless integration into diverse production setups. Whether shaping complex sequences or refining sonic textures, the MV-1's SYSEX tweakability empowers musicians to sculpt their musical visions.

All Roland Verselab MV-1 SYSex begin with: F0 41 10 00 00 00 6F 12 aa aa aa aa.

aa aa aa aa, are four hex numbers that are the 'address' of the parameter to change. After that you have more data, a checksum byte, and F7 to end the MIDI sysex.

Conventions used, for number with a border xx:

• tr = 07 + track number in hexadecimal (08 for Kick, 09 for Hats, etc)
• mu = 00 for mute (or Off), 01 for unmute (or On)
• cs = Roland data checksum, seems to be ignored in current firmware, can be 00
• v1 v2 = value from 00 00 (0) to 0f 0f (255), 8 bits are split over 2 bytes, the 1st nibble is always 0
• v1 v2 v3 = value from 00 00 00 00 (0) to 0f 0f 0f (4095), 12 bits are split over 3 bytes, the 1st nibble is always 0

Below I won't repeat the first 8 bytes sequence!

Tracks: mute/pan/volume/etc

• Mute/Unmute Track tr: 10 00 tr 0D mu cs F7
• Volume of Track tr: 10 00 tr 31 v1 cs F7
• Pan of Track tr: 10 00 tr 32 v1 v2 cs F7
• Reverb of Track tr: 10 00 tr 34 v1 v2 cs F7
• Delay of Track tr: 10 00 tr 36 v1 v2 cs F7

Example:

• Mute Track 1 full message: F0 41 10 00 00 00 6F 12 10 00 08 0D 00 5B F7
• Unmute Track 1 full message: F0 41 10 00 00 00 6F 12 10 00 08 0D 01 5A F7

Global MFX

• MFX ON: 10 00 18 01 01 56 F7
• MFX OFF: 10 00 18 01 00 57 F7

Multi-mode filter tone

All MFX parameters will start with 10 00 18 addr 08 00, where addr is the hex address of a parameter. For example if the multi-mode filter is enabled in your MFX, address 14 is where the tone parameter can be changed:

• 10 00 18 14 08 00 v1 v2 cs F7

Value from 0 to 255 in 2 bytes (see above).

Mid/Side Delay mix

• Mid: 10 00 18 10 08 00 v1 v2 cs F7
• Side: 10 00 18 3C 08 00 v1 v2 cs F7

Filter value from 00 00 (0) to 07 0f (127)

Note: my MVAVE MS1 seems to be limited to 16 bytes for Sysex over Bluetooth!! So these long 17 bytes sysex will fail to be transmitted properly.

• mode 2: 10 00 18 10 08 00 00 02 cs F7

Change the MFX type to X

MFX is hard to change live, as you have to scroll through a nice list of effects! So this SYSEX is a game changer 😁 The X value can be found in the following table below. The values were found in the Jupiter X documentation.

Dawless sysex send

If you don't have a DAW and/or PC, you can use the following solutions:

• An Android device, with MIDI commander from Bordero, plus a USB MIDI cable, or a 'MVAVE MS1' adapter to send the codes via Bluetooth MIDI.
• For iOS devices, Mozaic is a great tool to send anything to MIDI devices
• Custom Arduino or Raspberry PI code
