Help requested sequencing Korg Microkorg with Arturia Beatstep

Hello. I’ve hooked up my BS to MK, set midi channel on both, set Global position to pre on MK, reversed the polarity on my 3.5 to 5 pin adapter (both ways, to be safe as I don’t have original arturia adapter). Still getting nothing. I’ve sequenced the MK with an mpc1000 with general ease. The BS plays nicely with Ableton via usb. Can anybody offer any advice? Thanks in advance!
