MIDI "Chocolate" šŸ« controller with the Mod Dwarf, an introduction

Sounds to me like a lever to increase chances to break usb port heavily, when you pull usb cable accidentally. (And that’s inevitable at some point, imho). We have only one port on the quite expensive device to risk like that.

One thing is to just connect the dongle, but when you also have a cable on the floor between chocolate and dongle waiting for you to hit it by a foot when moving around and being focused on the guitar, it is somewhat another story without a happy end quite probably. I would suggest using USB hub instead to reduce levering almost three times. Using some velcro to mount usb hub to the side of MOD should be even better, if you can find a hub that fits.

Just tested the M-VAVE MIDI bluetooth USB dongle and seems that exp1 signals are not sent via bluetooth, isn’t it?

If you are asking about expression pedal connected to the chocolate, it’s CC values are sent via bluetooth towards MDX just fine for me. Had to invert signals in advanced custom mode though.

If I connect the chocolate to dwarf via USB cable, exp1 works. It doesn’t when connected via bluetooth MIDI USB dongle.

I do not have a lot of ideas, unfortunately.

TRS port in chocolate is multifunctional, and can be switched between TRS MIDI output and expression pedal input. Would try checking this setting just in case (However how it works with usb then?)

Also I recall that there is a firmware upgrade possibility, maybe you have outdated firmware?

(Only mobile app had a button for upgrade for me)

Thanks, I wasn’t aware of new firmware availability via cubesuite app. Unfortunately, midi signals for exp1 are not sent via midi dongle still.

@redcloud, try to update the bluetooth adapter dongle too. Maybe works.

Note: I don’t tested an expression pedal with Chocolate.

That’s what I did but with no luck.

just switch the expression pedal values in the settings :wink:

Hi @SrMouraSilva,

Thank you for creating the useful manual that the M-VAVE company doesn’t provide. It looks like most of the images now have dead links, which is a shame for such a complete and helpful post.

It’s true. A sad moment here :confused:

I will try to find them, but I’m not sure if I yet have them

So nice to read about the chocolate controller here. Using many of them for loopy pro :-). This reads as if this is the right controller for my freshly received Dwarf :-).

B.t.w. in loopy pro I am able to use single & double triggers & hold to have 3 Midi funtions on ONE Midi button. I’m completely new to the dwarf… is it possible to use a hold on the footswitch to lets say delete a Looper Track? But hitting it once shortly records the track? And maybe doubleclick would jump to next track…

Hi @MCCY,

In the advanced custom mode, you can set different MIDI messages for a short and a long pressure. The big problem with this mode is that the message is sent only when you release the switch, which makes it almost unusable for a looper as you want it to react when you hit the switch for precision.

In the custom control mode, you can solve this last problem by activating ā€œvisual behaviorā€. But this mode doesn’t allow to send different MIDI messages with a short and a long pressure.

So you have to choose between precision or having two functions per switch. I don’t know about the double trigger possibility. It might depend on the plugin. I know the Looperlative LP3 allows it with the Dwarf switches but I have to try with the Chocolate.

I wouldn’t say this device is ideal with the Dwarf for two reasons :

  • the one I mentioned above
  • the lack of visual feedback

But I don’t think you can find anything cheaper to have 4 additional switches and the possibility to connect a basic TRS expression pedal. I also like the size and apparent sturdiness. As you already own one, it would be a shame not to use it because it sure enhances the possibilities of you Dwarf.

Oh, wow, that would be perfect. Didn’t get that so far… Will have to try it out, how that works… I assume, I should go slowly as I find that there is so much more to discover… and that maybe wont have an end :wink:

This is a big problem to me. Sometimes I don’t know what is the current state an I prefer turn off and re turn on the Dwarf to try to avoid play something with the wrong effect LOL
(in my case I’m using it with Looper)

But in 1.12 the mod API allows display shows a custom information temporarily. So I thought develop a Gossiper plugin, to shows if a specific Midi message was received or something like this. But now I don’t know how can I use text atom. @falkTX, do you have some material or a simple plugin that I can look for inspiration?

Good news. The minimized looper controls on the LP3 have long press and double tap functions that work with the Chocolate if you disable ā€œvisual behaviorā€. Be careful, there’s a bug in the CubeSuite app that makes ā€œvisual behaviorā€ appear ā€œoffā€ when you start the app, even when it’s actually ā€œonā€. In this case, you have to turn it on and off.

@SrMouraSilva
You’re right, it’s something I hadn’t well anticipated before buying the Chocolate. Good luck with your plugin. Otherwise, maybe someday, the MOD OS will allow us to assign 2 different controls to the same parameter and the action of an external control will activate the Dwarf controls feedback. That could be a feature request.

Hello !
Who has already disassembled the m-vave chocolate ? I would like to know what is inside, in particular if the main component is an arduino (like uno or Leonardo for example as they are MIDI class compliant), the idea is to try to hack the m-vave ro add functionalities such as a second expression pedal input jack.
I also wonder how I will continue to configure it if one day the app CubeSuite is removed from the AppStore

I recently got one of these, my plan was to try it out and if it did not do what I wanted to strip the innards and replace with a self-build microcontroller system (which I have done in the past) … the Chocolate was quite cheap and less than getting the separate elements individually … however as it seems sufficient at present I’ve not done this nor opened it up.

Fair point about the app tho … might have to do some snooping on the bluetooth connection to see if I can figure out the protocol.

Hello,
Thanks for the feedback.
Do you know if it can be configured with the app 's version Pc or Mac with usb wired connection instead of Bluetooth ?
