Hi @zynthianers!
I just committed a new feature that simplify the task of splitting the keyboard. It allow to specify a “Note Range + Octave Transpose” for every layer (channel). Combined with “Clone”, it’s a beast of splitting + layering 
Simply update your zynthian and bold-click a layer for accessing the layer options …
You can adjust the range using 2 encoders and also with your keyboard.
Enjoy!
Could the other encoder be an overall transpose ( +/- 12 semitones)?
Good idea but maybe call it “note transpose” or similar to align with the “octave transpose” title of the other encoder.
I would also like to draw the honourable gentlemen’s attention to the rather excellent arrangement of a keyboard along the lower edge of the display . . . . 
Horses for courses 
You read my mind, @wyleu!
I removed the old “transpose” stuff and add it to the new Note Range modal.
Enjoy!
Halftone? May I suggest changing it to semitone?
Canaries & Parrots . ???. … It all canaries and parrots in there . . . .
no wonder we have problems !!!
Done!
thank you very much for satisfied my request !
Zynthian now can substitute an expander rack on live gig!!!
I love it, @jofemodo! It looks very clean and professional.
Tell me when you test it
It’s pretty neat that you can set the keyrange by pressing the actual keys.
It’s also a bit annoying when you are trying to find the right octave for your bass.
But the keypress feature should stay.
Go Zynthian! 
You cant set the range from the GUI screen. Probably not too relevant from a touchscreen, maybe more so for a mouse user …
If mouse on enable keyboard range selection…? might get a bit contrived and touch screen might not be a good place to enable that …
Thoughts?
Thats feature is so great. I was in a battle with midi filters, this saves me a lot of time, thanks so much.
I’m not very good plaiyng keyboards, I make the insolence of start practicing Tarkus. I make a lot of mistakes but I think I will be able of play the full song without mistakes before die 
Tarkus.zss (26.0 KB)
I used two keyboards in Channel 1 and 2. The only problem that I have now is not with zynthian but in my Keyboards is very difficult to change the MIDI Chanels.
thats really nice!
Zarkus is absolutely zynthianic, man!!! Thanks!!
