Boss 200 series pedals

Using Morningstar to control Boss OD/MD/DD/EQ-200 pedals.

I have an MC8 controlling OD-200, MD-200, and DD-200 pedals. I’m new to the Boss 200 series and to Midi. As I figure out how this works, I’ll post info to this thread.


My first lesson was toggling on and off the 200-series pedals. The On/Off stomp switch for all three pedals is controlled by CC#28. But you have to send it both a 0 CC message AND a 127 CC message to toggle it from one state to the other.

Also, sending the pedal a PC message will automatically turn the pedal On.

When I power up my pedalboard, all three pedals turn on automatically. I programmed a switch on the MC8 to turn them all off. That required six CC messages, two to each pedal.

Next, I wanted to turn them all off but have them shift to the Manual mode before doing so. That way, if I hit the On/Off switch on the DD200, it would turn on in the Manual mode (i.e., PC#0).

To do that with a single press on the MC8, I had to first send the three pedals a PC-0 message on the “Press” action, and then two CC messages (0 and 127) to each pedal of the three pedals on the “Release” action. It works!

Sending both PC and CC messages to the pedal left it in the “On” state. It seems PC messages override CC messages on my Boss pedals.


Here are the default CC#s for the DD200.

  • Time knob: 17
  • Feedback knob: 18
  • E.Level knob: 19
  • Param knob: 22
  • Tone knob: 20
  • Mod knob: 21
  • On/Off switch: 28
  • Memory switch: 82
  • Ctl 1: 80 (I’m not sure what this is yet!)
  • Ctl 2: 81
  • Expression: 16
  • Effect On/Off: 27 (I’m not sure what this does yet).

I hope this is useful! ~Bud.

This info applies to BOSS DD/MD/OD-200 pedals. It may also apply to other BOSS pedals.

SAVING NEW SOUNDS. When saving new settings to a Program Channel (1 thru 127), consider starting at PC-5 to avoid overwriting the original factory settings in PC 1 thru 4. If you overwrite the factory settings in PC-1 thru 4 and later want to recover that sound, you will need to do a Factory Reset. (Ask me how I know this!)

BOSS DD/MD/OD-200 FACTORY RESET. This will recover the originally programmed settings for Program Memory slots 1 thru 4. Fortunately, it will not overwrite any firmware updates you’ve made. However, it will restore your MIDI parameters to their default settings (e.g., the pedal will default to MIDI Channel 1, Memory extended only to 4, etc.).

Here’s how to return the DD-200 to its factory-set state. (You can do this on your pedalboard.)

  • While holding down the [ON/OFF] switch and [MEMORY/TAP] switch, turn on the power (insert a plug into the INPUT-A jack). The display indicates “FCt.”
  • Press the [MEMORY/TAP] switch. The display indicates “Sur.” If you decide to cancel, press the [MEMORY] button.
  • Press the [MEMORY/TAP] switch. The factory reset is executed.
  • When the display indicates “Fin,” turn the power off and on again.

HOW TO FIND THE PEDAL’S FIRMWARE VERSION. Before you start a firmware update, check the system program version of your DD/MD/OD-200. (You can do this on your pedalboard.)

  • Hold down the [MEMORY] button and insert a plug into the INPUT-A jack. The power comes on and the version is displayed on the Display.
  • If this shows the latest version (check the Boss website), there’s no need to update your DD/MD/OD-200 pedal.
  • After verifying the displayed version, switch off the power.

SOME KEY MIDI PARAMETERS & SETTINGS. To check your pedal’s MIDI settings, with the pedal on:

  • Simultaneously press the two black buttons on your pedal (Tap Division and Memory, or Param and Memory) to enter the MIDI menu mode.
  • Turn the large knob on the top row next to the display (Time, Rate, or Param) to select a MIDI parameter.
  • Press the (Time, Rate, or Param) knob to view the parameter’s setting.
  • Twist the (Time, Rate, or Param) knob to change the parameter’s setting.
  • Press the (Time, Rate, or Param) knob again to return to the parameter-view mode.
  • Continue selecting parameters and adjusting settings as desired.
  • When finished, simultaneously press Tap Division and Memory (or Param and Memory) to exit the MIDI menu mode.

Here are a few MIDI settings to check or make on your BOSS DD/MD/OD-200 pedals.

Parameter Full Name Remarks/Setting
Ett Memory Extended To Specifies the memory switching upper range. The default is 4; so after pressing the Memory/Tap switch four times, the fifth press cycles the pedal back to the Manual mode (green light on the pedal). Setting this to something higher will require extra pushes on the Memory/Tap switch before the pedal cycles back to Manual (PC-0).

Important: all 127 Program Channels are available regardless of the Ett setting. “Ett” only affects the Manual/Tap switch. Thus, you could put your four frequently used settings in PC-1 thru 4 and use your MIDI to access less frequently used settings stored in the higher PCs (5 thru 127).|

|rCh | MIDI Receive Channel | Give each pedal its own channel # (1-16). |
|CCi | Control Change in | Set to ON to receive CCs. |


Could you help me by a Problem concerning boost function on a od-200?

Thanks you very much

Sure. What seems to be the issue? What is happening, and how is that different from what you think should be happening?

I try to configurate the mc-6 in the following way.

Button A: engage/disengage the od 200 with CC#28 (it works)

Button B: od 200 Chanel 1 On (it works)
Button C: od 200 Chanel 2 On (it works)
Button D: od 200 Chanel 3 On (it works)
Button E: od 200 Chanel 4 On (it works)
(with PC# 1 to 4)

Button F: source audio ventris ON/Off (it works)

The Problem is the boost function with CC#83.

I tried several Times to makr the following
It had to let the boost “Off” when i change the Chanel.
the result is ever “sometimes boost is on, sometimes off”

In other words…for example:
switch Chanel 1, boost OFF.
Switch Chanel 2, boost is OFF.
re-switch Chanel 1, boost is ON.
re-switch Chanel 2, boost is ON.

In short, on on, off, off on, on, off, off etc…

I have posted à video on my you tube Chanel.

Here’s à link to my Problem.

Excuse my englisch, i live in europe. I hope you understand what i mean?

Hey Miguelito! your English is perfect! Thank you for reaching out to me ;).

I see you are toggling the Boost on and off each time you press each switch (for example, each time you press MC-6 button B). The same happens each time you press MC-6 button C.
Also, you have “Toggle Mode On” in your editor. That is why each MC-6 button toggles with every other push.

I can help you work through this. First, I need to understand the bigger picture. What are you trying to do with MC-6 buttons B and C? If you are trying to do something that does not include activating the boost, I would make MC-6 button A the Boost toggle button, and program other actions for buttons B and C.

There is more, but let’s see where this takes us!


Button B is for od-200 Chanel 1,
C for 2, D for 3 and E for 4.

You know the OD 200…so you know the boost is a second overdrive as… A boost.

That’s what i want. I have Programmed every Chanel of the of 200 with a boost function that i wich to select with a second pressure on the mc-6 Button.

Button B to select chanel 1 (PC#) and another pressure on the same Button B to select the boost (CC#28)… And Button B to deselect the boost.

But what i want is: no matter wich Sound i 've just played, by selecting a od200 chanel it should must be with boost off.

Thanks for your help

If you programm the PC message with ‘on first engage’ and activate ‘clear preset toggle’ in bank settings you should be fine. Every time you press another switch the position of all other presets will flip back to position 1.
If you don’t want the preset to be always in position 1 after you engaged another preset, because for example you want to be able to toggle a reverb on/off without changing the position of the OD preset, there is a way to do this, too.
But this will take a lot more programming.

Hello Guitar Wolf.

i have programmed the mc-6 like you suggest.
It works; but i don’t needed to activate “on first engage” because simply activate “clear preset toggles” was enough.

you can see how it works here:

As someone who has spent the last couple of weeks wrangling a MC-8 with a:

  • OD-200
  • MD-200
  • IR-200
  • DD-500
  • MD-500
  • RV-500

I’ve spent a lot of time working through various midi related things and I used this thread as my starting point.

Now I feel like I’ve got most of my setup complete, I thought I would share a couple of points that related to the OD-200 and the MD-200.

The first is use of CC #28 as the On/Off switch vs CC #27as Effect on/off.

As has been pointed out, CC #28 requires two CC messages to simulate a foot press on the pedal. But for me this never helped as all this did was toggle the state of the pedal. It never guaranteed it was either on or off. It was just the opposite of what it was before I sent the two CC values.

Yes, if I sent a patch change I could guarantee the pedal was on, and then I could use CC #28 to turn it off, but when things got more complicated, it could end up toggled the wrong way.

What I found was it was much better to use CC #27 as this is an actual on/off setting, where sending 0 will turn it off and sending 127 will turn it on. You only need to send one CC message!

You can set your Toggle buttons on your MC-8 to say the correct thing in terms of On/Off because you know sending a 0 will turn it off and sending a 127 will turn it on.

Also if you want to start with a certain patch but have it off, you send the PC to the patch you want, then CC #27 => 0, and it’s off.

This was a game changer for me with more complicated setups and much easier for using Toggle and Long Press settings.

The second point relates to using the Boost in the OD-200.

It’s been pointed out that you use CC #83 for this, and 127 is on and 0 is off, but the thing for me is I wanted to see the light for the boost on/off on the pedal and by default the pedal was in memory mode and I had to hold down the Memory/Boost button to get it into Boost mode where it would then flash until the boost was engaged.

What I found out is if you are not going to use the Memory/Boost button on the actual unit to change memory settings (and I don’t) you can set that switch to Boost mode.

You have to consult the manual for this one, you change the Memory Switch Function to BST.

When you do this, that button will only turn the Boost on and off, and won’t change the memory. But it means that the Boost light will come on every time you turn it on via MIDI and you don’t have to put it in flashing mode by holding the button down.

For my use, this was exactly what I wanted. But I spent a lot of time trying to simulate the long hold on the button to get it into flashing Boost mode when I first tried to do this, so hopefully this will save someone some time!

Also the treble boost on that unit is fantastic. I never thought I wanted a treble boost until I tried it.


@Pearlgiver - could I bother you for a bit more information here please?
I’m so frustrated with these devices at this point that I’d even be happy to pay you for the time if you can help me figure some of this stuff out with a bit more clarity.
I am somewhat of a newbie regarding MIDI, but the Boss 200 series are beyond any difficultly level I’ve come across so far.

Here are the things I would like to figure out with my Morningstar MC6…in order of importance.

  • DD-200 - turn it on and off

  • DD-200 - tap tempo

  • DD-200 - increase/decrease effect level

  • DD-200 - increase/decrease feedback

  • EQ-200 - turn it on and off

  • EQ-200 - cycle through presets (up/down)

I would love any insight you can offer on these to make it a bit clearer on how to set it up in the Morningstar software. I really think I need specific instructions, as I am not entirely clear on all the MIDI lingo that is being used.

As I said, I’d even be happy to pay for your time…if you can write out some sort of instructions or spend 15-20 minutes with me on a ZOOM call or whatever.


Hey Joseph,

It’s hard for me to say without knowing where you are at midi-wise.

Which channel do you have assigned on your EQ-200, and which one is assigned on your DD-200? These are selected on the pedals themselves.

Next, remember Boss requires both a CC#0 and a CC#127 to toggle off and on. Here is a good video tutorial to get started:

Lastly, I recently picked up an EQ-200 but haven’t done anything with it yet.

Hope this helps!

Also, the first half of this video is excellent to help you get your Boss pedals set up for Midi control:


WockBuz, excellent info! Thanks for sharing! ~Bud.

hello and thanks for help.

All the time i switched on and off with CC#28.
Just now I wanted to try with CC#27 as you do, to have a more stable configuration as you suggest, and to save a Cc message.
Except that I realize that I cannot put 2 values (min and max) but only one…
do you have an explanation?
