Keyboard Split for B3 Upper/Lower Manual and Basspedal in Cubase

Dear folks, I have a Launchkey MK3 61, a Hammond XPK100 Basspedal the Steinweg UR22 MK3 and the B3 V2 VST installed via Cubase. What I’am trying to do, is to direct the right part of the keyboard to the upper manual, the left part to the lower manual and the Basspedal to the Pedals of the B3 VST.
The Launchkey keyboard has no keyboard split. So I can’t adress different midi channels. The keys send on Channel 1 the basspedal on Channel 3. Does anybody have an idea how to set this up in Cubase 13 LE Edition?
Or asked the other way round would this work with Cubase 13 Pro or Artist with the input midi transformer or with the Keylab Mk3 61, which seems to have the possibility to split the keys. Love to hear from you. Many thanks in advance. Best regards Martin

Hi @SriVischnu. Welcome to the community.

If i understand the Keylab 3 correctly, then it does’nt have midi Split unless you use Analog Labs Split functionality. In this case you actually use two different B3 V2 presets - one for each part in Analog Lab. So as i see it, then this is not what you are looking for in this case.


The B3 V2 have a Split mode. You can access that in the right panel.
Since you don’t have 61 + 61 + 25 keys and there even only are 127 midi notes, then this has limitations, but you will be able to do a lot using the B3 V2 Split mode.
You could for example have 31 notes on a 61 key controller to play the upper manual and the other 30 keys to play the lower manual and then use another controller to play the 25 pedals. You could even set split points so a single controller play all 3 manuals.

B3 V2 also have a Multimode that use midi channels.
To play all notes on the 3 manuals of an instance of the B3 V2 independently at the same time you will need to send midi notes on 3 different midi channels to it. One midi channel for each manual.
The B3 preset you use also need to be set to work with multiple incoming midi channels in B3’s right panel. By default B3 split presets are using midi channel 1,2 and 3.

Please consult the B3 manual section “3.2.15. The Keyboard Preferences window” for informations about the bove mentioned Split and Multi modes.

The rest is about your DAW’s functionality. In my DAW i or example can place the same B3 instance on 3 different tracks, and then send midi notes on the 3 different midi channels to them.

I know nothing about Cubase, so i don’t know, if it has a functionality to do this a different way.

I can only suggest you try things out, and find the solution that’s best for you.
I hope this helps.

hi lbh, thank you for your answer. I don,t have the Analog Lab, only the V Collection. I created 3 instances in cubase. But the Problem is the keyboard split into two midi channels. my novation launchkey mk3 does not support that and my version of cubase does not have the midi input transformer, seems that i have to upgrade the one or the other. Does the arturia keylab mk keyboard support spltting the keys?

Hi again @SriVischnu ,

No - As i wrote then Keylab MK3 does afaik unfortunately not support keyboard midi Split the way you ask it to work. FYI an Analog Lab is part of the keyboard package. But that will not help you in this case anyway.
BTW: I don’t think a midi input transformer create midi splits anyway either.

You shall in the case you can this option use the same instance of B3 on the 3 tracks like i wrote - not use 3 different instances.

Did you try out the Split mode in B3 like i wrote about? That option only require one midi channel and one track.
