Expression pedal in ableton through midi pedal (Boss FC 50)

  • [RESOLVED] Expression pedal in ableton through midi pedal (Boss FC 50)

Hi, i’m trying to configurate an expression pedal wich it’s connected in my midi pedalboard. I’m not having trouble with the pedalboard, i’ve already configured that part and it’s working in ableton 10, i’m sending keystrokes by pressing te pedal buttons.
But now i have this expression pedal. Bome (i’m using bome classic by the way) is recibing the signal, but i don’t know how to configure it, because in ableton i don’t recive the signal. May be it’s because a bad configuration in ableton, but i tried almost every chosie possible and recived no signal at all.
I don’t know if i expressed well my issue, but if you can help me to solve it i will be grateful.

Hi, thanks for your question!  First, open the log window and ensure you are getting MIDI-IN. If your expression pedal is plugged into the EXP1 jack you should see something like B0 07 pp (where pp is the value). If you are plugged into EXP2 jack, it should be something like B0 0F pp (again where pp is the value). You should be able to see the value change as you move the pedal. If you cannot get this far then perhaps you have the wrong type of Expression pedal plugged into the jack. They say to use a Roland EV-5 or Boss EV-10 only.

If you have gotten this far, then the good new is that you have a working expression pedal.  Now since Bome MIDI Translator Classic does not include virtual MIDI ports, you will have to find another alternative. Search the web for LoopBE or LoopMIDI and download and install.  I provided links but be careful for spyware as they may not be the official ones. Personally I like LoopMIDI better because I can name my virtual ports anything I want. I use it so much I decided to donate to the author.



Set the new virtual MIDI port installed as the output port in Bome MIDI Translator Classic, and use the same port for input in Ableton Live.  Then you should be in business.

You can set up a translator to translate to a different CC value to Ableton Live if you wish.

That really worked! You are awesome, but (always has to be a but), why i’m not getting the full range? I mean, when i set something to control with the pedal it only goes to, let’s say, a quarter of the entire knob. And also it’s not detected by external vst like guitar rig.
Again, thanks for you response, and you are very quick too, i’m honestly thankful

Does the input go the full range 0-127? If not, maybe the expression pedal is bad.

Actually i don’t know how to view that. In bome, when i assign the pedal to incoming message it goes for B0 10 pp to B0 10 19. It’s that 19 the whole range of midi input that i get? I solved the other part, the guitar rig thing, but happens the same

Mmm… i was testing my launchkey in bone and seems like it’s like i thought, It’s really a pitty, I was so close! Thank for all of your answers, you really helped me out, i have learned a lot. I will try to get one of the pedals that you mentionated before.
Thank you!

You have either a bad or a wrong type of expression pedal or a bad FC50 controller.

New update, the pedal is bad. I will have to change the potentiometer, I made some tests by moving the whole knob by hand and it worked, so i have to repair that. Again, thanks for everything, very helpful and complete.

You bet, probably a 100K pot for those. The old ones used to go bad a lot.
