The XK33c has been the portable alternative when I can’t bring the B3.
After a while I got tired of assembling and disassemling it on each gig (the upper and lower manual are separate). I contacted carptenter Magnus Caris in Orsa, Sweden and we custom designed a case so it always can be transported with the two manuals assembled. It has fold out legs, a special pocket för the half moon switch.
It really improved the usability if you always play with two manuals!
